Add small ports for config, secrets, storage, and logging, a runtime that holds them, and an Emitter that can stand in for vscode.EventEmitter later. The default runtime uses the package.json setting defaults, no secrets, in-memory storage, and stderr, so unit tests need no setup. The extension installs VS Code adapters first thing in activate. Logger and HttpClient now read settings through the config port, and Logger writes through the log sink. The logLevel watcher and the dev mode check move to the VS Code logger adapter. Logger.time/timeEnd used console.time on stdout, which the MCP server needs for protocol messages, so they now log at DEBUG through the sink.

Add small ports for config, secrets, storage, and logging, a runtime that holds them, and an Emitter that can stand in for vscode.EventEmitter later. The default runtime uses the package.json setting defaults, no secrets, in-memory storage, and stderr, so unit tests need no setup. The extension installs VS Code adapters first thing in activate. Logger and HttpClient now read settings through the config port, and Logger writes through the log sink. The logLevel watcher and the dev mode check move to the VS Code logger adapter. Logger.time/timeEnd used console.time on stdout, which the MCP server needs for protocol messages, so they now log at DEBUG through the sink. * refactor(core): read the remaining core settings through the config port The cache manager, component fetcher, discovery config, CI file matcher, and reference resolver still read settings straight from vscode.workspace. Route those reads through the runtime config port so the MCP server can supply its own settings. Same keys, same defaults. Move the componentSources watcher out of ComponentCacheManager into activate. It calls the same forceRefresh and logs the same lines, but the cache manager no longer has to subscribe to VS Code config events. discoveryConfig no longer needs its lazy vscode require, and gitlabCiFileMatcher only uses vscode for types now, so both load under plain Node. --------- Co-authored-by: eFAILution --- src/extension.ts | 12 +++++++ src/providers/componentDetector.ts | 4 +-- src/services/cache/componentCacheManager.ts | 39 +++++---------------- src/services/component/componentFetcher.ts | 5 +-- src/services/component/discoveryConfig.ts | 21 ++++------- src/utils/gitlabCiFileMatcher.ts | 7 ++-- tests/unit/discovery-config.test.ts | 24 +++++++++++-- tests/unit/gitlabCiFileMatcher.test.ts | 30 ++++++++++++++++ 8 files changed, 86 insertions(+), 56 deletions(-) create mode 100644 tests/unit/gitlabCiFileMatcher.test.ts diff --git a/src/extension.ts b/src/extension.ts index 5e7f5f57..5f754292 100755 --- a/src/extension.ts +++ b/src/extension.ts @@ -74,6 +74,18 @@ export function activate(context: vscode.ExtensionContext) { throw cacheError; } + // Refetch every source when the configured sources change + context.subscriptions.push( + vscode.workspace.onDidChangeConfiguration(e => { + if (e.affectsConfiguration('gitlabComponentHelper.componentSources')) { + logger.debug('[ComponentCache] Configuration changed, forcing refresh...', 'ComponentCache'); + cacheManager.forceRefresh().catch(error => { + logger.debug(`[ComponentCache] Error during config refresh: ${error}`, 'ComponentCache'); + }); + } + }) + ); + // Listen for configuration changes context.subscriptions.push( vscode.workspace.onDidChangeConfiguration(e => { diff --git a/src/providers/componentDetector.ts b/src/providers/componentDetector.ts index e8523c38..7266dc8a 100755 --- a/src/providers/componentDetector.ts +++ b/src/providers/componentDetector.ts @@ -13,6 +13,7 @@ import type { GitApi, GitRepository } from '../types/vscode-git'; import type { CachedComponent, RefType } from '../types/cache'; import { DEFAULT_BRANCH_CACHE_TIME_SECONDS } from '../constants/timing'; import { resolveBranchFreshness, type BranchFreshnessResult } from '../utils/branchFreshness'; +import { getRuntime } from '../core/runtime'; // Re-export so existing consumers (e.g. localComponentResolver, validationProvider) keep their import path. export type { ComponentParameter }; @@ -781,8 +782,7 @@ async function lookupExpansionContext(forUri: vscode.Uri): Promise>('componentSources', []); if (!source) { return { kind: 'no-context' }; diff --git a/src/services/cache/componentCacheManager.ts b/src/services/cache/componentCacheManager.ts index 7264cc42..e04a98e1 100644 --- a/src/services/cache/componentCacheManager.ts +++ b/src/services/cache/componentCacheManager.ts @@ -14,6 +14,8 @@ import { CACHE_LOCATION_MEMORY_ONLY, DEFAULT_COMPONENT_TYPE_PROJECT, } from '../../constants/cache'; +import { CONFIG_DEFAULTS } from '../../core/config/defaults'; +import { getRuntime } from '../../core/runtime'; // Bump when the on-disk CachedComponent shape changes.

TokenManager now reads and stores tokens through the runtime secrets port and fires changes through the core Emitter. When the port can't store, setTokenForProject throws the same "SecretStorage not available" error as before. It also keeps a gitlab-token-instances list in storage, because secret stores can't be listed and the MCP launcher will need to know which instances have tokens. The token prompt moves to the VS Code auth prompt adapter behind a new AuthPromptPort. Hosts without a UI return undefined, which means public access. The unused ExtensionContext params and setSecretStorage are gone.

Both now go through the runtime storage port, and the cache manager fires through the core Emitter. The ExtensionContext params and setContext are gone. A new persistent flag on the storage port drives the cache status location text, which used to key off whether a context was set. Add an eagerRefresh option (default true, as today). A host that passes false still loads the stored cache but skips the startup fetch of every source, so the MCP server makes no network calls until a tool needs components. Drop the commands re-export from the component services barrel so the cache modules that import the barrel stay free of vscode. Everything under src/services except commands.ts now loads under plain Node. * fix(core): harden events, token index, and cache logs found in review - Emitter logs and skips a throwing listener, like vscode.EventEmitter, so one bad listener can't fail a token save or a cache update. - The token instance list is best effort. A failed write is logged and the token still counts as saved. A malformed list is logged, and an instance string that embeds credentials is never recorded. - Request dedup keys hash the auth token so the raw token never sits in getDeduplicationStats(). - Cache logs report the real storage location and warn when storage isn't persistent. - A failed refresh after a componentSources change logs at warn. --------- Co-authored-by: eFAILution --- src/adapters/vscode/storage.ts | 1 + src/core/emitter.ts | 15 ++- src/core/ports.ts | 2 + src/extension.ts | 9 +- src/services/cache/componentCacheManager.ts | 127 +++++++++----------- src/services/cache/unifiedCache.ts | 29 ++--- src/services/component/index.ts | 3 - src/services/component/tokenManager.ts | 31 ++++- src/utils/httpClient.ts | 7 +- tests/unit/componentCacheManager.test.ts | 125 +++++++++++++++++++ tests/unit/httpClient.test.ts | 12 ++ tests/unit/runtime.test.ts | 19 +++ tests/unit/tokenManager.test.ts | 50 +++++++- 13 files changed, 329 insertions(+), 101 deletions(-) create mode 100644 tests/unit/componentCacheManager.test.ts diff --git a/src/adapters/vscode/storage.ts b/src/adapters/vscode/storage.ts index 4919f3a5..6e02b098 100644 --- a/src/adapters/vscode/storage.ts +++ b/src/adapters/vscode/storage.ts @@ -3,6 +3,7 @@ import type { StoragePort } from '../../core/ports'; export function createVscodeStorage(memento: vscode.Memento): StoragePort { return { + persistent: true, get: async (key: string) => memento.get(key), update: async (key, value) => memento.update(key, value), }; diff --git a/src/core/emitter.ts b/src/core/emitter.ts index 966df046..aaa32c70 100644 --- a/src/core/emitter.ts +++ b/src/core/emitter.ts @@ -5,7 +5,12 @@ export interface Disposable { export type Event = (listener: (value: T) => void) => Disposable; -/** A minimal stand-in for `vscode.EventEmitter` that works without VS Code. */ +import { Logger } from '../utils/logger'; + +/** + * A minimal stand-in for `vscode.EventEmitter` that works without VS Code.

Add src/core/validation with validateIncludes, which returns plain findings (code, severity, message, file, 0-based range, metadata) for component and local includes. Callers supply the reference resolver, the component lookup, and the local include reader, so nothing in core touches vscode. Messages, codes, ranges, and metadata are the ones the provider publishes today. The provider switches over in the next change. The local include text parser moves to src/core/localInclude.ts, and the reference result types move to src/core/references.ts. The provider modules re-export both, so callers are unchanged. New unit tests pin the findings for the extension-host fixtures (local-include, duplicate-include, flow-inputs, merge-key, revalidate-on-edit, enum-options) and for component includes with a fake lookup. --- src/core/localInclude.ts | 138 ++++++++ src/core/references.ts | 15 + src/core/validation/findings.ts | 54 ++++ src/core/validation/includeLines.ts | 121 +++++++ src/core/validation/validateIncludes.ts | 295 ++++++++++++++++++ src/core/validation/validateLocalInclude.ts | 141 +++++++++ src/providers/componentDetector.ts | 14 +- src/providers/localComponentResolver.ts | 106 +------ tests/unit/support/fakeResolver.ts | 7 + tests/unit/support/fixtureIncludes.ts | 32 ++ tests/unit/validateIncludesComponents.test.ts | 155 +++++++++ tests/unit/validateIncludesLocal.test.ts | 178 +++++++++++ 12 files changed, 1143 insertions(+), 113 deletions(-) create mode 100644 src/core/localInclude.ts create mode 100644 src/core/references.ts create mode 100644 src/core/validation/findings.ts create mode 100644 src/core/validation/includeLines.ts create mode 100644 src/core/validation/validateIncludes.ts create mode 100644 src/core/validation/validateLocalInclude.ts create mode 100644 tests/unit/support/fakeResolver.ts create mode 100644 tests/unit/support/fixtureIncludes.ts create mode 100644 tests/unit/validateIncludesComponents.test.ts create mode 100644 tests/unit/validateIncludesLocal.test.ts diff --git a/src/core/localInclude.ts b/src/core/localInclude.ts new file mode 100644 index 00000000..4cdca2d9 --- /dev/null +++ b/src/core/localInclude.ts @@ -0,0 +1,138 @@ +/** + * Turn the text of an `include: - local:` target into the synthetic component the providers and validator use. + * Reading the file is the host's job; this module only parses. + */ + +import * as path from 'path'; +import * as yaml from 'js-yaml'; +import { Logger } from '../utils/logger'; +import { isYamlNode, GITLAB_CI_SCHEMA } from '../utils/yamlParser'; +import { isParameterDefault } from '../parsers/parameterDefaultShape'; +import { buildLocalComponentUrl } from '../providers/localIncludeParser'; +import type { ComponentParameter } from '../types/git-component'; + +const logger = Logger.getInstance(); + +/** The component a local include with a `spec:` block resolves to. */ +export interface LocalIncludeComponent { + name: string; + description: string; + parameters: ComponentParameter[]; + source: string; + url: string; + originalUrl: string; + sourcePath: string; +} + +/** + * The outcome of resolving a `local:` include, discriminating the reasons resolution can fail to yield a component. + * + * `unreadable` and `no-spec` look identical to callers that only want the component, but they are opposites to the + * validator: `unreadable` is a real problem (the included file is missing or can't be read) worth a diagnostic, + * whereas `no-spec` is a legitimate plain include (hidden jobs, `.pre`/`.post`, cache config) with nothing to + * validate and must stay silent.

Add src/core/validation/versionFindings.ts. It computes outdated refs from text plus a reference resolver and a version fetcher, reads versionCheck.enabled and severity through the config port, and turns each ref into a finding. Each finding also carries a suggested edit that bumps the pinned ref, which is the edit the extension's quick fix makes today. Add src/core/validation/componentLookup.ts with the pure parts of findComponentInCache, parseComponentIdentity, and the version lookup entry, taking the cache contents as input. --- src/core/validation/componentLookup.ts | 90 ++++++++++++++++++++++ src/core/validation/versionFindings.ts | 101 +++++++++++++++++++++++++ tests/unit/componentLookup.test.ts | 72 ++++++++++++++++++ tests/unit/versionFindings.test.ts | 56 ++++++++++++++ 4 files changed, 319 insertions(+) create mode 100644 src/core/validation/componentLookup.ts create mode 100644 src/core/validation/versionFindings.ts create mode 100644 tests/unit/componentLookup.test.ts create mode 100644 tests/unit/versionFindings.test.ts diff --git a/src/core/validation/componentLookup.ts b/src/core/validation/componentLookup.ts new file mode 100644 index 00000000..767ef7fa --- /dev/null +++ b/src/core/validation/componentLookup.ts @@ -0,0 +1,90 @@ +/** + * Pure lookups over the cached component list, shared by every host that validates against the component cache. + */ + +import { Logger } from '../../utils/logger'; +import { + findAnyCachedComponentVersion, + findCachedComponentVersion, + parseComponentIdentity, + type ComponentIdentity, +} from '../../utils/cachedComponentLookup'; +import type { CachedComponent } from '../../types/cache'; +import type { Component } from '../../types/git-component'; + +const logger = Logger.getInstance(); + +/** + * Parse a component URL into its cache identity, treating a reference with no `@ref` as `main`. + */ +export function parseComponentRef(url: string): Required | null { + const identity = parseComponentIdentity(url); + if (!identity) { + logger.debug(`[ValidationProvider] Not a component URL: ${url}`, 'ValidationProvider'); + return null; + } + return { ...identity, version: identity.version ??

What stays in the provider is the VS Code part: document events, diagnostic collections, code actions, the input quick pick, and the cache-backed component lookup it hands to the core. The gitlab.example.com mock component stays in the provider's lookup, so the core never sees it. The metadata types move to src/core/validation/metadata.ts. validationMetadata.ts keeps the attach and read helpers and re-exports the types. The provider drops from 1504 to 940 lines. Diagnostic messages, codes, ranges, severities, and metadata are unchanged; the unit tests added with the core validator pin them. --- src/core/validation/findings.ts | 2 +- src/core/validation/metadata.ts | 86 +++ src/core/validation/validateIncludes.ts | 2 +- src/providers/findingToDiagnostic.ts | 29 + src/providers/validationMetadata.ts | 102 +--- src/providers/validationProvider.ts | 712 +++--------------------- 6 files changed, 207 insertions(+), 726 deletions(-) create mode 100644 src/core/validation/metadata.ts create mode 100644 src/providers/findingToDiagnostic.ts diff --git a/src/core/validation/findings.ts b/src/core/validation/findings.ts index 5041ef01..4cf24a85 100644 --- a/src/core/validation/findings.ts +++ b/src/core/validation/findings.ts @@ -3,7 +3,7 @@ * returns them as JSON.

Add src/core/referenceResolver.ts, which expands GitLab variables over a RepoContextPort (the file's GitLab remote, and a non-GitLab remote check) and the runtime config port for the component source fallback. The remote URL parsers move to src/core/gitRemote.ts. The raw git spawn fallback moves to src/adapters/node/repoContext.ts. That file also provides a git CLI RepoContextPort for the MCP server. componentDetector keeps createReferenceResolver(uri) as a thin wrapper over a VS Code port with the same lookup order as before, so callers are unchanged. --- src/adapters/node/repoContext.ts | 115 +++++++++++ src/core/gitRemote.ts | 136 +++++++++++++ src/core/referenceResolver.ts | 94 +++++++++ src/providers/componentDetector.ts | 275 ++------------------------- tests/unit/gitCliRepoContext.test.ts | 61 ++++++ tests/unit/referenceResolver.test.ts | 102 ++++++++++ 6 files changed, 529 insertions(+), 254 deletions(-) create mode 100644 src/adapters/node/repoContext.ts create mode 100644 src/core/gitRemote.ts create mode 100644 src/core/referenceResolver.ts create mode 100644 tests/unit/gitCliRepoContext.test.ts create mode 100644 tests/unit/referenceResolver.test.ts diff --git a/src/adapters/node/repoContext.ts b/src/adapters/node/repoContext.ts new file mode 100644 index 00000000..f5200e96 --- /dev/null +++ b/src/adapters/node/repoContext.ts @@ -0,0 +1,115 @@ +/** + * Repository context from the `git` CLI, for hosts without the VS Code Git extension (the MCP server).

The VS Code side moves to src/adapters/vscode/workspace.ts. That covers the Git extension repo root, the workspace folder fallbacks, and the open-buffer fast path. localComponentResolver keeps its exports as thin wrappers, so callers are unchanged. Add a done-check unit test. It loads every src/core module under plain Node, then runs the core validator over the local-include and enum-options fixtures through a filesystem workspace port and a fake component lookup. --- src/adapters/vscode/workspace.ts | 98 ++++++++++++++++++++++ src/core/localInclude.ts | 66 ++++++++++++++- src/providers/localComponentResolver.ts | 105 ++---------------------- tests/unit/coreValidation.test.ts | 78 ++++++++++++++++++ tests/unit/support/fixtureIncludes.ts | 30 +++++-- 5 files changed, 267 insertions(+), 110 deletions(-) create mode 100644 src/adapters/vscode/workspace.ts create mode 100644 tests/unit/coreValidation.test.ts diff --git a/src/adapters/vscode/workspace.ts b/src/adapters/vscode/workspace.ts new file mode 100644 index 00000000..d12c26fa --- /dev/null +++ b/src/adapters/vscode/workspace.ts @@ -0,0 +1,98 @@ +/** + * The extension's {@link WorkspacePort}: the VS Code Git extension and workspace folders pick the resolution root, + * and reads prefer an open editor buffer over the file on disk.

The argument was built even with debug off, and a 500-byte YAML alias bomb blocked for seconds before throwing. Documents (and local include targets) with more than 100 aliases are skipped. - isUnsupportedLocalPath treats \ as a separator and rejects drive letters, UNC paths, and NUL bytes. The core resolver also checks that the joined path stays inside its root. - Local include targets read from disk must be regular files of at most 1 MB, in the Node reader and the VS Code adapter. - git runs with fixed args, no shell, stdin and stderr ignored, a 5s timeout, a 64 KB output cap, and GIT_DIR, GIT_WORK_TREE, and GIT_CONFIG* stripped with GIT_TERMINAL_PROMPT=0. It resolves on close so stdout isn't truncated. - The local: line regex no longer backtracks quadratically on long whitespace lines. - parseGitLabRemoteUrl ignores remotes whose host isn't a plain hostname, like git@gitlab.com@evil.example:g/p.git. --- src/adapters/node/readTextFile.ts | 27 ++++ src/adapters/node/repoContext.ts | 100 +++++++------ src/adapters/vscode/workspace.ts | 7 +- src/core/gitRemote.ts | 8 + src/core/localInclude.ts | 32 +++- src/core/validation/validateIncludes.ts | 12 +- src/providers/localIncludeParser.ts | 18 ++- src/utils/yamlParser.ts | 22 +++ tests/unit/securityHardening.test.ts | 190 ++++++++++++++++++++++++ tests/unit/support/fixtureIncludes.ts | 9 +- 10 files changed, 358 insertions(+), 67 deletions(-) create mode 100644 src/adapters/node/readTextFile.ts create mode 100644 tests/unit/securityHardening.test.ts diff --git a/src/adapters/node/readTextFile.ts b/src/adapters/node/readTextFile.ts new file mode 100644 index 00000000..bf686a76 --- /dev/null +++ b/src/adapters/node/readTextFile.ts @@ -0,0 +1,27 @@ +import { open } from 'node:fs/promises'; +import { MAX_LOCAL_INCLUDE_BYTES } from '../../core/localInclude'; + +/** + * Read a regular file as UTF-8, refusing anything that isn't a file or is larger than `maxBytes`. + * + * @returns The text, or `null` when the path is missing, not a regular file, too large, or unreadable. + */ +export async function readBoundedTextFile( + absolutePath: string, + maxBytes: number = MAX_LOCAL_INCLUDE_BYTES +): Promise { + try { + const handle = await open(absolutePath, 'r'); + try { + const stats = await handle.stat(); + if (!stats.isFile() || stats.size > maxBytes) { + return null; + } + return await handle.readFile({ encoding: 'utf8' }); + } finally { + await handle.close(); + } + } catch { + return null; + } +} diff --git a/src/adapters/node/repoContext.ts b/src/adapters/node/repoContext.ts index f5200e96..06225017 100644 --- a/src/adapters/node/repoContext.ts +++ b/src/adapters/node/repoContext.ts @@ -11,23 +11,66 @@ import type { RepoContextPort, RepoRemoteContext } from '../../core/referenceRes const logger = Logger.getInstance(); +const GIT_TIMEOUT_MS = 5000; +const MAX_GIT_OUTPUT_BYTES = 64 * 1024; + +export interface CommandLimits { + timeoutMs?: number; + maxOutputBytes?: number; +} + +/** + * The environment for child git processes: no variables that point git at another repository or config, and no + * credential prompts. + */ +function childEnv(): NodeJS.ProcessEnv { + const inherited = Object.entries(process.env).filter( + ([name]) => name !== 'GIT_DIR' && name !== 'GIT_WORK_TREE' && !name.startsWith('GIT_CONFIG') + ); + return { ...Object.fromEntries(inherited), GIT_TERMINAL_PROMPT: '0' }; +} + /** - * Run `git` in `cwd`. + * Run a fixed command (no shell) in `cwd` with a timeout and an output cap. * - * @returns Trimmed stdout when git exits 0, else `null` (not a repository, no such remote, git missing). + * @returns Trimmed stdout when the command exits 0 within the limits, else `null`. */ -function runGit(cwd: string, args: string[]): Promise { +export function runCommand(command: string, cwd: string, args: string[], limits: CommandLimits = {}): Promise { + const { timeoutMs = GIT_TIMEOUT_MS, maxOutputBytes = MAX_GIT_OUTPUT_BYTES } = limits; return new Promise((resolve) => { - const git = spawn('git', args, { cwd, stdio: 'pipe' }); - let output = ''; - git.stdout.on('data', (data: Buffer) => { - output += data.toString(); + const child = spawn(command, args, { + cwd, + env: childEnv(), + stdio: ['ignore', 'pipe', 'ignore'], + windowsHide: true, + timeout: timeoutMs, + killSignal: 'SIGKILL', }); - git.on('exit', (code: number | null) => resolve(code === 0 ? output.trim() : null)); - git.on('error', () => resolve(null)); + const chunks: Buffer[] = []; + let outputBytes = 0; + let overflowed = false; + child.stdout.on('data', (data: Buffer) => { + outputBytes += data.length; + if (outputBytes > maxOutputBytes) { + overflowed = true; + child.kill('SIGKILL'); + return; + } + chunks.push(data); + }); + // `close` waits for stdout to drain; `exit` can fire before the last chunk arrives. + child.on('close', (code: number | null) => { + resolve(code === 0 && !overflowed ?

The protocol is hand-rolled: newline-delimited JSON-RPC 2.0 over stdio, with initialize, ping, tools/list, and tools/call. It negotiates protocol versions 2025-11-25, 2025-06-18, 2025-03-26, and 2024-11-05, and only sends outputSchema and structuredContent when the negotiated version has them. Tool arguments are validated against each tool's schema. Results are capped in size, and unexpected errors don't leak details. The transport is the only writer to stdout. A stray console.log is redirected to stderr so it can't corrupt the stream. The first tool, get_component_spec, returns a component version's inputs, versions, and latest stable version. Spec text is cleaned of control and bidi characters and length-capped. GitLab error bodies are never passed through. esbuild builds the server to out/mcp/server.js, and a plugin fails the build on any vscode import. The bundle ships in the VSIX.

After that the runtime is locked against replacement. - Config: --config > GCH_CONFIG_JSON > GCH_LOG_LEVEL > the root's .gitlab-component-helper.json > its .vscode/settings.json (JSONC, via jsonc-parser) > defaults. Unknown or wrongly-typed keys are dropped, and gitlabToken is refused. - Tokens: GCH_TOKEN_ and GITLAB_TOKEN (for GITLAB_HOST) are read once and deleted from the environment. The variable name is lossy, so a token is only bound to a host named by the launcher's settings, GCH_TOKEN_HOSTS, or GITLAB_HOST, never by a workspace file. Two trusted hosts that share a variable name get neither token. - Storage: one JSON file per key in a 0700 cache dir, written atomically as 0600. - Files: only regular files of at most 1 MB under the realpath'd roots. Traversal, symlinks out, and missing files all get the same answer. - Network: HTTPS only, to gitlab.com, componentSources instances, and hosts with a token. Private, loopback, and link-local addresses are refused, including after DNS resolution. A refused host gets a message saying how to allow it. - git: an absolute path found on PATH, only for files under the roots, and GIT_CEILING_DIRECTORIES stops discovery above them. Child processes no longer inherit GCH_* or GITLAB_TOKEN. --- esbuild.mcp.js | 2 + package-lock.json | 8 ++ package.json | 1 + src/adapters/node/repoContext.ts | 68 ++++++++---- src/core/ports.ts | 10 ++ src/core/runtime.ts | 9 ++ src/mcp/adapters/args.ts | 46 ++++++++ src/mcp/adapters/config.ts | 128 +++++++++++++++++++++ src/mcp/adapters/gitPath.ts | 27 +++++ src/mcp/adapters/network.ts | 85 ++++++++++++++ src/mcp/adapters/secrets.ts | 82 ++++++++++++++ src/mcp/adapters/storage.ts | 61 ++++++++++ src/mcp/adapters/workspace.ts | 68 ++++++++++++ src/mcp/bootstrap.ts | 85 ++++++++++++++ src/mcp/main.ts | 9 +- src/mcp/services.ts | 12 +- src/utils/httpClient.ts | 5 +- tests/unit/gitCliRepoContext.test.ts | 19 +++- tests/unit/mcpConfigSecrets.test.ts | 125 +++++++++++++++++++++ tests/unit/mcpSpawn.test.ts | 12 +- tests/unit/mcpWorkspaceNetwork.test.ts | 147 +++++++++++++++++++++++++ tests/unit/support/mcpProcess.ts | 14 +++ 22 files changed, 998 insertions(+), 25 deletions(-) create mode 100644 src/mcp/adapters/args.ts create mode 100644 src/mcp/adapters/config.ts create mode 100644 src/mcp/adapters/gitPath.ts create mode 100644 src/mcp/adapters/network.ts create mode 100644 src/mcp/adapters/secrets.ts create mode 100644 src/mcp/adapters/storage.ts create mode 100644 src/mcp/adapters/workspace.ts create mode 100644 src/mcp/bootstrap.ts create mode 100644 tests/unit/mcpConfigSecrets.test.ts create mode 100644 tests/unit/mcpWorkspaceNetwork.test.ts diff --git a/esbuild.mcp.js b/esbuild.mcp.js index 43a214a2..cf43921e 100644 --- a/esbuild.mcp.js +++ b/esbuild.mcp.js @@ -28,6 +28,8 @@ function mcpConfig({ production = false, outfile = 'out/mcp/server.js' } = {}) { format: 'cjs', platform: 'node', target: 'node22', + // Prefer ESM builds: jsonc-parser's UMD build requires its own files at runtime, which a bundle can't satisfy. + mainFields: ['module', 'main'], outfile, minify: production, sourcemap: !production, diff --git a/package-lock.json b/package-lock.json index 7bbf5b14..c695d4ff 100644 --- a/package-lock.json +++ b/package-lock.json @@ -36,6 +36,7 @@ "husky": "^9.1.6", "is-ci": "^4.0.0", "js-yaml": "^5.5.0", + "jsonc-parser": "3.3.1", "minimatch": "^10.2.6", "mocha": "^12.0.3", "npm-run-all": "^4.1.5", @@ -6570,6 +6571,13 @@ "dev": true, "license": "MIT" }, + "node_modules/jsonc-parser": { + "version": "3.3.1", + "resolved": "https://registry.npmjs.org/jsonc-parser/-/jsonc-parser-3.3.1.tgz", + "integrity": "sha512-HUgH65KyejrUFPvHFPbqOY0rsFip3Bo5wb4ngvdi1EpCYWUQDC5V+Y7mZws+DLkr4M//zQJoanu1SP+87Dv1oQ==", + "dev": true, + "license": "MIT" + }, "node_modules/jsonfile": { "version": "6.2.1", "resolved": "https://registry.npmjs.org/jsonfile/-/jsonfile-6.2.1.tgz", diff --git a/package.json b/package.json index ad0fcaf9..062194f6 100644 --- a/package.json +++ b/package.json @@ -344,6 +344,7 @@ "husky": "^9.1.6", "is-ci": "^4.0.0", "js-yaml": "^5.5.0", + "jsonc-parser": "3.3.1", "minimatch": "^10.2.6", "mocha": "^12.0.3", "npm-run-all": "^4.1.5", diff --git a/src/adapters/node/repoContext.ts b/src/adapters/node/repoContext.ts index 06225017..579a0265 100644 --- a/src/adapters/node/repoContext.ts +++ b/src/adapters/node/repoContext.ts @@ -8,6 +8,7 @@ import * as path from 'path';

The server never writes files. Findings carry suggestedEdits for mechanical fixes (version bumps, and renaming an unknown input that is one typo away from a declared one). The initialize instructions tell agents to validate first, read the spec for the exact version before changing inputs, and apply the edits themselves. Output is built for untrusted content. Messages are fixed text. Names, descriptions, and defaults from YAML or specs go in cleaned, length-capped data fields. Provided input values never appear, since they can be alias-bomb trees. Findings are capped. Hosts the allowlist refused come back as blockedHosts with a hint on how to allow them. --- src/mcp/main.ts | 5 +- src/mcp/services.ts | 9 +- src/mcp/tools/ciFiles.ts | 73 ++++++++++ src/mcp/tools/context.ts | 15 ++ src/mcp/tools/findingOutput.ts | 117 ++++++++++++++++ src/mcp/tools/index.ts | 25 ++++ src/mcp/tools/usageTools.ts | 112 +++++++++++++++ src/mcp/tools/validateTools.ts | 110 +++++++++++++++ src/mcp/tools/validation.ts | 105 ++++++++++++++ tests/unit/mcpSpawn.test.ts | 21 ++- tests/unit/mcpValidationTools.test.ts | 190 ++++++++++++++++++++++++++ 11 files changed, 778 insertions(+), 4 deletions(-) create mode 100644 src/mcp/tools/ciFiles.ts create mode 100644 src/mcp/tools/context.ts create mode 100644 src/mcp/tools/findingOutput.ts create mode 100644 src/mcp/tools/index.ts create mode 100644 src/mcp/tools/usageTools.ts create mode 100644 src/mcp/tools/validateTools.ts create mode 100644 src/mcp/tools/validation.ts create mode 100644 tests/unit/mcpValidationTools.test.ts diff --git a/src/mcp/main.ts b/src/mcp/main.ts index 706207aa..312d3b6d 100644 --- a/src/mcp/main.ts +++ b/src/mcp/main.ts @@ -6,7 +6,7 @@ import { Writable } from 'node:stream'; import { Logger } from '../utils/logger'; import { McpServer } from './server'; import { createStreamTransport } from './transport/stdio'; -import { createGetComponentSpecTool } from './tools/getComponentSpec'; +import { createTools, SERVER_INSTRUCTIONS } from './tools'; import { createComponentServices } from './services'; import { bootstrap } from './bootstrap'; import { ArgsError, USAGE } from './adapters/args'; @@ -36,7 +36,8 @@ async function main(): Promise { const context = await bootstrap(process.argv.slice(2), process.env, process.cwd()); const server = new McpServer({ info: { name: SERVER_NAME, title: SERVER_TITLE, version: typeof GCH_VERSION === 'string' ?

The definition runs out/mcp/server.js with the editor's own Node (process.execPath with ELECTRON_RUN_AS_NODE=1) and passes: - a --root per workspace folder - the effective settings minus gitlabToken as GCH_CONFIG_JSON - a cache dir under global storage Tokens are only added in resolveMcpServerDefinition, when VS Code actually starts the server. That covers every instance in the token index, plus every componentSources instance with a stored secret, so tokens saved before the index existed still work.

That includes workspace settings, and GCH_TOKEN_ names are lossy, so a repository that set componentSources to gitlab-example.com got the gitlab.example.com token. - The extension now passes tokens as one GCH_TOKENS_JSON map of exact host to token. The server reads it and deletes it first, and binds each token only to its key. - GCH_TOKEN_ (for terminal use) binds only to a host named in GCH_TOKEN_HOSTS, which is now read before it's deleted, or in --config. - The extension picks token hosts from the token index plus the user's global componentSources, never workspace or folder values. - Only launcher-trusted hosts widen the network allowlist: --config, GCH_TRUSTED_HOSTS (the user's global sources), token hosts, and gitlab.com. A host named only by a repo file or workspace settings is blocked. The hint tells the agent to use user settings, never repo files. - Workspace config files may only set catalog and checking behavior, not network, cache, or logging settings. - Settings are parsed into null-prototype objects and looked up with own-property checks, so __proto__ can't smuggle values. - The allowlist matches url.host, with the default port normalized. --- src/adapters/vscode/mcpDefinitionProvider.ts | 12 ++- src/mcp/adapters/config.ts | 56 ++++++++++--- src/mcp/adapters/network.ts | 19 +++-- src/mcp/adapters/secrets.ts | 73 ++++++++++++----- src/mcp/bootstrap.ts | 28 +++---- src/mcp/launchConfig.ts | 34 ++++---- src/mcp/tools/validateTools.ts | 2 +- tests/unit/mcpConfigSecrets.test.ts | 51 ++++++++++-- tests/unit/mcpLaunchConfig.test.ts | 16 +++- tests/unit/mcpTokenTrust.test.ts | 82 ++++++++++++++++++++ tests/unit/mcpWorkspaceNetwork.test.ts | 9 ++- tests/unit/support/bootstrapProbe.ts | 17 ++++ 12 files changed, 321 insertions(+), 78 deletions(-) create mode 100644 tests/unit/mcpTokenTrust.test.ts create mode 100644 tests/unit/support/bootstrapProbe.ts diff --git a/src/adapters/vscode/mcpDefinitionProvider.ts b/src/adapters/vscode/mcpDefinitionProvider.ts index 399a0a85..345b92f6 100644 --- a/src/adapters/vscode/mcpDefinitionProvider.ts +++ b/src/adapters/vscode/mcpDefinitionProvider.ts @@ -14,6 +14,7 @@ import { buildTokenEnv, effectiveSettings, tokenCandidateHosts, + userSourceHosts, } from '../../mcp/launchConfig'; export const MCP_PROVIDER_ID = 'gitlabComponentHelper.mcp'; @@ -27,9 +28,14 @@ export interface TokenSource { readonly onDidChangeToken: Event; } +/** componentSources from the user's global settings (or the defaults), never from the workspace or a folder. */ +function userComponentSources(): unknown { + const inspected = vscode.workspace.getConfiguration(CONFIG_SECTION).inspect('componentSources'); + return inspected?.globalValue ?? inspected?.defaultValue ??

UNC and \\?\ paths are refused up front. - readBoundedTextFile stats first and opens with O_NONBLOCK, so a FIFO or device is never read. Repo config files are read through the workspace guard, so a symlink out of the root is ignored. - Output text also drops Unicode tag characters, zero-width and direction marks, word joiners, BOM, the Arabic letter mark, and line and paragraph separators. File paths are cleaned and capped everywhere. documentationUrl is kept only when it's https. - Addresses are parsed to bytes, so IPv4 carried in IPv6 (mapped, compatible, NAT64, 6to4) gets the same checks. 100.100.100.200 and fd00:ec2::254 (cloud metadata) are blocked. - lockRuntime freezes the ports and the network policy. HttpClient refuses to send when the runtime is locked and no policy is installed. --- src/adapters/node/readTextFile.ts | 12 ++- src/core/runtime.ts | 11 ++- src/mcp/adapters/config.ts | 10 +- src/mcp/adapters/network.ts | 69 +++++++++++--- src/mcp/adapters/workspace.ts | 12 ++- src/mcp/bootstrap.ts | 2 +- src/mcp/tools/findingOutput.ts | 8 +- src/mcp/tools/getComponentSpec.ts | 12 ++- src/mcp/tools/sanitize.ts | 11 ++- src/mcp/tools/usageTools.ts | 4 +- src/mcp/tools/validateTools.ts | 3 +- src/utils/httpClient.ts | 6 +- tests/unit/mcpGetComponentSpec.test.ts | 2 +- tests/unit/mcpHardening.test.ts | 123 +++++++++++++++++++++++++ 14 files changed, 253 insertions(+), 32 deletions(-) create mode 100644 tests/unit/mcpHardening.test.ts diff --git a/src/adapters/node/readTextFile.ts b/src/adapters/node/readTextFile.ts index bf686a76..ca61ad73 100644 --- a/src/adapters/node/readTextFile.ts +++ b/src/adapters/node/readTextFile.ts @@ -1,6 +1,10 @@ -import { open } from 'node:fs/promises'; +import { constants } from 'node:fs'; +import { open, stat } from 'node:fs/promises'; import { MAX_LOCAL_INCLUDE_BYTES } from '../../core/localInclude'; +// Opening a FIFO for reading blocks until a writer appears; O_NONBLOCK makes it return at once.

The MCP server stops a tool call after 60s with an isError result.

The MCP path asks the version cache to throw (throwOnError, off by default, so the extension is unchanged) and turns failures into tool errors. validate_ci_file lists failed bases in summary.versionLookupFailed and says so in its text. Lookups are memoized per base URL for the run, failures included. get_component_spec still returns the inputs, with an empty version list and a note, when only the versions fail. - check_component_versions runs even when versionCheck.enabled is off, since the call is explicit. validate_ci_file notes when the check is off. - The directory walk also skips .venv, venv, target, dist, build, out, .next, vendor, .terraform, and coverage. It walks in name order and caps directories visited as well as files. - validate_ci_file and check_component_versions document the suggestedEdits coordinates, and their output schemas type range and suggestedEdits fully. - Invalid tool arguments come back as isError results the model can correct. An unknown tool is still -32602. notifications/cancelled drops the response. The response chain catches its own errors. - The server logs unhandled rejections and uncaught exceptions to stderr, exits cleanly on EPIPE, and logs an oversized line before closing. - VS Code: no definition without a workspace folder, cwd is the first folder, and a token revision in the definition version makes VS Code restart the server after a token change.

A path outside the workspace now names the roots. Refs #370 * fix(mcp): look past our own error codes when classifying a fetch failure NetworkError carries its own code (NETWORK_ERROR), and the classifier stopped at it, so a TLS, DNS or connection cause was never reached and every network failure came back as unknown.

Refs #370 * fix(mcp): give expired and mismatched certificates their own hint The trust-store advice (NODE_EXTRA_CA_CERTS) only helps when Node does not know the issuer.

Now the extension rewrites the seed shortly after its cache changes, and the server re-reads it when the file's mtime changes, checking at most once a second.

The MCP server fetched a component's spec from GitLab on + every tool call. Its services went straight to the fetcher, so even a + spec it had fetched a minute earlier was fetched again. Only version + lists used a cache. + + The extension already holds most of these specs, but in VS Code's + global state, which only the extension can read.

A spec pinned to a tag (a clean X.Y.Z, or an entry + the extension classified as a tag) is reused while cached, as the + extension does. Any other ref (a branch, ~latest, a partial version) + is reused only for cacheTime. Failed fetches are never stored. Only + spec fields are kept, and at most 500 entries, newest first. + - When VS Code starts the server, the extension writes the spec fields + of its component cache to mcp-seed/components.json in its global + storage (0600 in a 0700 folder, replaced atomically) and passes the + path in GCH_CACHE_SEED (src/mcp/cacheSeed.ts). The server reads it + bounded to 16 MB and shape-checked, and uses an entry when its own + cache has nothing fresh. A branch entry without a fetch time counts + as stale. The server never writes the seed. + - While mcp.enabled is on, the extension rewrites the seed 2 seconds + after its cache changes. A running server checks the seed file's + mtime at most once a second and re-reads it when it changed. A cache + reset in the extension is written as clearedAt, and the server drops + what it fetched before that time. + rationale: + - Tag-pinned specs are the bulk of real includes, and the extension already treats them as fixed, so both give the same answer. + - Branch refs can move, so a time limit keeps a moving spec from going stale for good. + - A file is the only thing both processes can read.
