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LLMs rely on outdated or generic information about the libraries you use.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• ❌ Code examples are outdated and based on year-old training data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No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.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
