MCP.Pizza Chef: sammcj

The mcp-package-docs server is an MCP server designed to provide large language models (LLMs) with efficient, structured access to package documentation across multiple programming languages. It supports Go, Python, NPM, and Rust ecosystems, leveraging native tools like 'go doc', Python's 'help()', and registry sources such as crates.io and docs.rs. The server offers smart documentation parsing with structured outputs including descriptions, usage examples, and symbol-specific lookups. It also supports fuzzy and exact search capabilities, enabling LLMs to retrieve focused, relevant documentation without context overload. This server enhances LLM-powered development tools by integrating language server protocol (LSP) features and multi-language package insights in real time.
