@RohitKrish46
This is a lightweight, plug-and-play MCP server that empowers any LLM to dynamically search and retrieve up-to-date documentation from popular AI libraries such as LangChain, LlamaIndex, and OpenAI.
Overview
What is MCP Docs Search Server?
A lightweight MCP server that searches and retrieves relevant documentation content from popular AI libraries like LangChain, LlamaIndex, and OpenAI using web search and content parsing. It acts as a bridge between LLMs and external documentation sources, enabling language models to query and fetch up-to-date documentation dynamically.
How to use MCP Docs Search Server?
Clone the repository, create a virtual environment with uv, install dependencies (mcp[cli], httpx, beautifulsoup4), and set the SERPER_API_KEY environment variable. Integrate with Claude Desktop by adding the server configuration to claude_desktop_config.json, then use the get_docs tool with a query and library name. Debug in real time using npx @modelcontextprotocol/inspector uv run main.py.

FAQ from MCP Docs Search Server
What dependencies does the server require?
It requires Python (managed via uv), the mcp[cli], httpx, and beautifulsoup4 packages, plus a Serper API key stored as the SERPER_API_KEY environment variable.
What libraries are currently supported?
LangChain, LlamaIndex, and OpenAI. More libraries can be added by updating the docs_urls dictionary.
How does the get_docs tool work?
It accepts a query string and a library name, searches for relevant documentation pages, fetches and parses clean text content, and returns the result to the LLM for further reasoning.
Can I debug the server in real time?
Yes. Use npx @modelcontextprotocol/inspector uv run main.py after installing Node.js 18+, then follow the port where the connection is set up.
How do I integrate this server with Claude Desktop?
Add the server configuration to claude_desktop_config.json under mcpServers, specifying the command uv with the directory and run main.py, then restart Claude Desktop.
