Overview

What is UV Documentation MCP Server?

An MCP server that provides programmatic access to UV documentation through a standardized API, exposing high‑level documentation sections and detailed command documentation (including subsections) as individual MCP resources.

How to use UV Documentation MCP Server?

Requires Python 3.13+ (minimum 3.10 for MCP SDK compatibility). Clone the repository, create a virtual environment, install dependencies with pip install -e ., then run the server with uv run uv-docs. For use with Claude Desktop, configure the MCP server settings using the uv command with the appropriate --directory and run arguments.

Key features of UV Documentation MCP Server

Hierarchical resource structure using uv-docs:// URIs (sections, commands, subsections)
Tools: update_cache and search_documentation for cache and real‑time queries
Prompt template summarize-docs for AI documentation summaries
Version‑aware caching with segmented section storage
Fully open‑source and publishable to PyPI

Use cases of UV Documentation MCP Server

AI assistants retrieving precise UV documentation sections on demand
Developers automating the lookup of UV CLI commands and their options
Integrating UV documentation into custom MCP‑compatible tools or workflows
Generating summaries of selected UV documentation areas for reporting

Frequently asked questions

What does the resource layer provide?

Resources expose UV documentation via URIs like `uv-docs://cli`, `uv-docs://cli/uv-cache`, and `uv-docs://cli/uv-cache/uv-cache-dir`, returning JSON with metadata and full documentation content.

How can I search documentation in real time?

Use the `search_documentation` tool, which accepts a `query` string and performs a live search over the UV documentation.

What are the runtime dependencies?

Python 3.10+ (3.13+ recommended) and the MCP Python SDK. The project is installed via `pip` and run with `uv` (or `uvx` for published versions).

How does caching work?

A version‑aware cache is initialized at startup. Each documentation section (CLI, settings, resolver) is cached separately. The cache is automatically updated when the live version changes, or manually via the `update_cache` tool.

Is authentication or specific transport required?

No authentication or special transport is mentioned. The server uses standard MCP communication over stdio, configured through MCP client settings.
