Library Docs MCP Server

This is an MCP (Model Context Protocol) server that allows you to search and fetch documentation for popular libraries like Langchain, Llama-Index, MCP, and OpenAI using the Serper API.

Features

• Search library documentation using a natural language query.
• Supports Langchain, Llama-Index, MCP, and OpenAI (Update the code to add other libraries).
• Uses the Serper API to perform site-specific searches.
• Parses and returns the documentation using BeautifulSoup.
• Provides updated documentation – useful for LLM models with knowledge cut-off dates.

Why Use This Server with LLMs?

Many LLM models, including those used in Claude Desktop and similar platforms, have a knowledge cut-off date and may not have access to the latest library documentation. This MCP server solves that problem by:

• Fetching real-time documentation from official sources.
• Providing up-to-date information for development and troubleshooting.
• Improving the accuracy and relevance of responses when working with new library updates.
