Tauri Documentation MCP server

tauri-docs-mcp

A read-only Model Context Protocol (MCP) server for resolving and querying a checked-in snapshot of official Tauri 2 documentation.

Requirements

• Node.js 20.19 or newer (supported Node LTS)
• npm 10 or newer

The committed package-lock.json is authoritative. Use npm install for local development and dependency changes; CI and reproducible installs use npm ci. Lockfile changes must be committed with dependency changes.

Install and run

Install the published package:

npm install --global tauri-docs-mcp

Or install it in a project and invoke the binary from node_modules/.bin:

npm install tauri-docs-mcp
npx tauri-docs-mcp

Build from a checkout, then run the compiled stdio server:

npm install
npm run build
node dist/src/index.js

Configure an MCP client to launch the installed binary over stdio:

{
  "mcpServers": {
    "tauri-docs": {
      "command": "tauri-docs-mcp"
    }
  }
}

Portable configurations for generic MCP clients, Claude Desktop, Cursor, and VS Code are in examples/mcp/. They pin the package version and use stdio only. Installable agent guidance is in skills/tauri-docs-mcp/SKILL.md.

The server writes MCP JSON-RPC messages only to stdout. It does not start an HTTP listener. Diagnostics are disabled by default; opt in with TAURIDOCSMCP_DIAGNOSTICS=1 and they are written to stderr as event names only (never request arguments, corpus content, secrets, or PII).

Tool contract

The server exposes two stable tools and one backwards-compatible legacy tool.

resolvetauridocs

Resolve the default snapshot or an explicit identifier:

{}

{ "identifier": "tauri@2" }

Supported identifiers are tauri, tauri@2, and the immutable snapshot ID tauri-2@58194ceb69424c4332b2780b196ced3a6fffb32b. Resolution is deterministic and returns snapshot, source revision, generated-at, version, and entry-count metadata. Unsupported identifiers return UNSUPPORTED_SNAPSHOT.

querytauridocs

Query content from the default or selected snapshot:

{ "query": "capabilities", "snapshot": "tauri@2", "limit": 3 }

query is required and must contain 1–200 non-whitespace characters and at most 16 whitespace-separated terms. snapshot is optional and accepts the resolver identifiers. limit is an optional integer from 1–10 (default 5). Results are bounded, deterministic, and include title, heading, section, canonical URL, content, corpus snapshot, source revision, Tauri version, and versionSensitive. Empty matches return results: [], not an application error. Inputs reject unknown fields.

Both tools are read-only and idempotent. They read only the checked-in corpus; there is no live fetching or arbitrary URL access.

Resource and lifecycle bounds

The shared tool contract enforces a 200-character query, 16 terms, 10 results, 1,200-character snippets, 8 KiB corpus entries, and 32 KiB serialized tool responses. The stdio frame buffer is capped at 64 KiB. EOF, transport errors, SIGINT, and SIGTERM share an idempotent shutdown path with a one-second cleanup bound; in-flight work is allowed to settle or is abandoned at that bound.

searchtauridocs (compatibility)

Existing clients can continue to call:

{ "query": "capabilities", "limit": 3 }

It remains supported with its existing response shape and limits. New clients should use resolvetauridocs followed by querytauridocs.

Application errors are returned with stable discriminated codes such as INVALIDINPUT, INVALIDQUERY, INVALIDLIMIT, and UNSUPPORTEDSNAPSHOT; protocol errors remain MCP protocol errors.
