npx -y @sylphx/lockdocs setup
Exact-version library docs from your lockfile — local, offline, no rate limits.
Docs · Quickstart · Tools · Benchmarks · Compare · How it works
A real terminal: one question, two installs. pydantic 1.10.18 answers BaseModel.dict() (pydantic/main.py:427), pydantic 2.9.2 answers model_dump() (pydantic/main.py:352). It opens with Next.js 14 vs 15 cookies().
Ask for the exact signature of BaseModel.model_dump in a project that pins pydantic 2.9.2 (the run in the demo above):
$ lockdocs api BaseModel.model_dump --tokens 300
[email protected] · pypi · .venv/lib/python3.12/site-packages · pinned in uv.lock
### pydantic.main.BaseModel.model_dump (method) — [email protected] pydantic/main.py:352
def model_dump(self, *, mode: Literal['json', 'python'] | str = 'python', include: IncEx | None = None, …) -> dict[str, Any]
Usage docs: https://docs.pydantic.dev/2.9/concepts/serialization/#modelmodel_dump
Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.
The same call in a pydantic 1 project answers that pydantic 1.10.18 has no model_dump, and shows the closest documentation instead.
npx -y @sylphx/lockdocs setup # add lockdocs to Claude Code, Codex, Cursor, VS Code, Claude Desktop, Windsurf, Gemini CLI
That's it. Using Claude Code only? claude mcp add lockdocs -- npx -y @sylphx/lockdocs mcp. setup detects the clients you have, writes their MCP config, and prints every change. Run it again and nothing changes. Then ask your agent something like "Use lockdocs: how do I reject unknown keys with the zod we use?"
From a terminal, inside any project:
npx -y @sylphx/lockdocs zod "reject unknown keys" # docs for the zod version in your lockfile
npx -y @sylphx/lockdocs api axum::Router::route # exact signature + doc comment
npx -y @sylphx/lockdocs resolve # every pinned version, and whether its docs are here
npx -y @sylphx/lockdocs fetch # once: add upstream docs at each version's git tag
Requires Node 18+. Confirm the install in your editor, open your project, and enable the server. Both links run npx -y @sylphx/lockdocs mcp locally; no API key is needed.
For VS Code from a terminal:
code --add-mcp '{"name":"lockdocs","command":"npx","args":["-y","@sylphx/lockdocs","mcp"]}'
Or add the server to .cursor/mcp.json:
{
"mcpServers": {
"lockdocs": {
"command": "npx",
"args": [
"-y",
"@sylphx/lockdocs",
"mcp"
]
}
}
}
For .vscode/mcp.json, use the VS Code servers format:
{
"servers": {
"lockdocs": {
"type": "stdio",
"command": "npx",
"args": [
"-y",
"@sylphx/lockdocs",
"mcp"
]
}
}
}
{
"mcpServers": {
"lockdocs": { "command": "npx", "args": ["-y", "@sylphx/lockdocs", "mcp"] }
}
}
Claude Code: claude mcp add lockdocs -- npx -y @sylphx/lockdocs mcp
Claude Code plugin: /plugin marketplace add SylphxAI/lockdocs, then /plugin install lockdocs@lockdocs
Codex (~/.codex/config.toml):
[mcp_servers.lockdocs]
command = "npx"
args = ["-y", "@sylphx/lockdocs", "mcp"]
The server answers for the client's workspace root (or its working directory, or LOCKDOCS_ROOT). Every tool also takes root.
Your agent writes code against the library version it remembers, not the one you installed. So it calls .dict() on a pydantic 2 model, cookies() without await on Next.js 15, and /:id routes on axum 0.8. Hosted doc servers help, but they guess the version from the prompt, cap free usage, and cannot see your private packages.
lockdocs takes the version question off the table:
package-lock.json, pnpm-lock.yaml, yarn.lock, bun.lock, Cargo.lock, uv.lock, poetry.lock, Pipfile.lock, requirements*.txt and go.mod. No library IDs, no "use v14" in the prompt.docs/ folders, plus the API reference in the package itself: .d.ts declarations with JSDoc, Python docstrings and stubs, rustdoc comments, Go doc comments. If it is installed, it is documented, including your private and internal packages.node_modules, your virtualenv, ~/.cargo/registry and the Go module cache. The optional model downloads once (129 MB, kept as 32 MB). Use --offline (or LOCKDOCS_OFFLINE=1) to prohibit all downloads; LOCKDOCS_EMBED=0 disables only the model. No account or hosted query quota. First-use upstream requests reveal the public repository and version being fetched, not your question or project files.--no-fetch or LOCKDOCS_FETCH=0 opts out; cached docs still work offline. Failures are reported alongside local answers, never replaced with latest-version docs.model_validate instead").package@version path:line.Three tools, cheap enough to call before every unfamiliar API:
Legacy copies bundled inside a package (zod/v3 inside zod 4, pydantic/v1 inside pydantic 2) rank below the current API.
The first docs or api query adds the selected dependencies' public release-tag docs once: it finds the GitHub repository in the package's own metadata and the git tag of your pinned version, resolves that tag to an immutable commit, and downloads only its docs folders (Markdown, MDX, reStructuredText, docs examples). It does not use ambient GitHub credentials or download major-version website docs by default. Previously opted-in docs-site caches are preserved and their provenance stays visible. lockdocs fetch remains available to prewarm docs and explicitly add major-version docs sites. Answers then cite [email protected] upstream:docs/01-app/.../cookies.mdx:12. See Upstream docs and fetching.
Registry package downloads remain opt-in; default upstream enrichment uses installed package metadata (plus the one-time embedding model download). If a pinned package is not installed (a fresh clone, CI, a lockfile you are reviewing), it says so and tells you how to install it. Pass --fetch (or set LOCKDOCS_FETCH=1, or lockdocs setup --fetch) to let it download exactly that version from the registry (npm tarball, PyPI wheel or sdist, crates.io .crate, Go module proxy zip) into its cache. Fetched answers say fetched from registry.npmjs.org. You can also ask for a version you do not use: lockdocs npm:[email protected] "strict object" --fetch.
105 questions whose correct answer depends on the version, over 15 libraries (zod, Next.js, React Router, pydantic, axum, tokio, Tailwind CSS, ESLint, Prisma, React, Vite, Express, SQLAlchemy, Django, FastAPI), each asked in a real project with that version installed. An answer passes when it contains the version-correct API and none of the other version's. Same questions and grader against Context7's anonymous API, on a GitHub-hosted runner (run):
lockdocs fetch (185 ms on first use), a fresh CLI process each time. Context7's hosted API took a median 2,583 ms in the earlier runs its reused answers come from.Method, questions, per-question results and scripts: benchmark page and bench/.
The same 105 questions are also asked through Sylphx Search — our platform's web search, whose technical-documentation vertical is the hosted index for docs that never ship inside a package — with bench/cloud.py. Local and cloud answer one corpus with one grader, so lockdocs and Sylphx Search are one index format and one ranking rather than two products.
Context7 knows many sites and guides that never ship inside a package, so for a question whose answer lives only on a docs website, it can do better. lockdocs is for the other case: when the version matters, when you are offline or rate-limited, and when the package is yours. They combine well.
(ecosystem, name, version) triples, marking direct dependencies..d.ts, Python, Rust and Go sources with tree-sitter into symbols with signatures, doc comments and qualified paths (z.object, tokio::task::spawn, pydantic.main.BaseModel.model_dump).Typical costs on a GitHub-hosted runner: indexing every declaration in Next.js 15 (7,700 symbols) takes about 0.4 s, zod 4 about 0.05 s, once per version; a query then takes 5-20 ms.

Prebuilt binaries for macOS (arm64, x64), Linux glibc (x64, arm64) and Windows x64 ship through npm; each GitHub release has them too. From source: cargo install --git https://github.com/SylphxAI/lockdocs lockdocs.
Everything above is free, under MIT. Pro adds two things for teams. Private sources: lockdocs reads your internal packages and docs from the private npm, PyPI, Cargo and Go registries and the GitHub Enterprise, GitLab and Bitbucket hosts you already use, with the credentials your .npmrc, uv, pip, Cargo, Go and git already hold, each sent only to its own host, inside the same resolve, docs and api tools and lockdocs fetch. And the upgrade report (lockdocs upgrade next 15.0.0, or upgrade_to in the docs tool): which APIs you call were removed, renamed or deprecated between your pinned version and the target, with your call sites. lockdocs Pro is US$120 per seat per year. The licence is checked offline: run lockdocs licence activate <token> (check it with lockdocs licence status, which warns during the last 30 days), or set LOCKDOCS_LICENCE_TOKEN in CI. Details: lockdocs Pro.
lockdocs reads files on your machine and answers over stdio. Network use: the embedding model once from huggingface.co (pinned revision, SHA-256 checked; LOCKDOCS_EMBED=0 or --offline skips it), and anonymous GitHub requests (git tag lookup and one codeload.github.com tarball, not the rate-limited REST API; a repository whose archive is too large or whose download fails is read file by file through the REST API instead) for public docs at the resolved release commit on first query. --fetch / lockdocs fetch also access public registries and major-version docs-site repositories; only these explicit fetches may use GITHUB_TOKEN / GH_TOKEN, and only on api.github.com (never on git, codeload or raw downloads; private repositories are not supported). Upstream requests disclose the repository, version and file paths, not your question, lockfile or project files. --no-fetch / LOCKDOCS_FETCH=0 disables query package/docs downloads; --offline / LOCKDOCS_OFFLINE=1 prohibits all downloads. The cache lives in your OS cache directory (LOCKDOCS_CACHE overrides it).
