XenoDocs MCP - Up-to-date Documentation For Any Library

❌ Without XenoDocs

LLMs rely on outdated or generic information about the libraries you use. You get:

• ❌ Code examples are outdated and based on year-old training data
• ❌ Hallucinated APIs that don't even exist
• ❌ Generic answers for old package versions

✅ With XenoDocs

XenoDocs MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.

Tell your AI assistant to search for library documentation:

Search for "authentication middleware" in the FastAPI library documentation

Find examples of async functions in the httpx library

XenoDocs fetches up-to-date code examples and documentation right into your LLM's context.

• 1️⃣ Write your prompt naturally
• 2️⃣ Ask for specific library documentation
• 3️⃣ Get working code answers

No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.

�️ Installation

Requirements

• Python >= 3.10
• VS Code, Cursor, Claude Desktop, or another MCP Client
• XenoDocs API Key (Get yours by creating an account at xenodocs.com/account/api-keys

Method 1: Using uv (Recommended)

uv add xenodocs-mcp-server

Method 2: Using pip

{
  "mcpServers": {
    "xenodocs": {
      "command": "uvx",
      "args": ["xenodocs-mcp-server"],

      }
    }
  }
}

Add to your Windsurf MCP configuration:

{
  "mcpServers": {
    "xenodocs": {
      "command": "uvx",

      "env": {
        "XENODOCS_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

Add to your Zed settings.json:

{
  "context_servers": {
    "xenodocs": {
      "source": "custom",
      "command": "uvx",
      "args": ["xenodocs-mcp-server"],
      "env": {
        "XENODOCS_API_KEY": "YOUR_API_KEY"
      }
    }
  }
}

🔨 Available Tools

XenoDocs MCP provides the following tools that LLMs can use:

• search_library_name: Search for matching library names in the XenoDocs documentation database.

  • library_name (required): The name or partial name of the library to search for
  • top_k (optional): Maximum number of matching libraries to return (default: 3, max: 20)

• search_library: Search for specific information within a library's documentation.

  • library_name (required): The exact name of the library to search in
  • query (required): The search query describing what you're looking for

💻 Development

Clone the project and install dependencies:

git clone https://github.com/Xenodocs/xenodocs-mcp-server.git
cd xenodocs-mcp-server
uv sync

Set your API key:

export XENODOCS_API_KEY="your-api-key"

Run the server:

uv run xenodocs-mcp-server

Testing with MCP Inspector

npx @modelcontextprotocol/inspector uv run xenodocs-mcp-server

🚨 Troubleshooting

If you get "command not found" errors:

1. For uv projects: Make sure you're in a directory with a pyproject.toml file
2. For pip installation: Use the Python module method:

   {
     "command": "python",
     "args": ["-m", "xenodocs_mcp_server.server"]
   }
   

If you see WARNING: XENODOCS_API_KEY not set!, make sure you've configured the API key in your MCP client configuration or as a system environment variable.

1. Restart your MCP client completely
2. Check that your installation method is working by running the command manually
3. Check client output/logs for MCP connection errors
4. Verify you have the correct Python version (>=3.10)
