MCP Protocol Documentation Lookup

Look up Model Context Protocol (MCP) documentation from modelcontextprotocol.io.

Instructions

You are looking up MCP protocol documentation to answer a question or guide implementation.

Step 1: Fetch the documentation index

Fetch the machine-readable index at https://modelcontextprotocol.io/llms.txt. This lists all ~90 documentation pages with titles and URLs. Use it to identify which page(s) are relevant to the question.

Step 2: Fetch the relevant page(s)

Append .md to page URLs for cleaner markdown content. For example:

• https://modelcontextprotocol.io/docs/learn/architecture.md
• https://modelcontextprotocol.io/specification/2025-11-25/server/tools.md

Fetch only the pages needed to answer the question — typically 1-3 pages.

Step 3: Cross-reference with our codebase

When relevant, use Read and Grep to cross-reference the documentation with our implementation in src/ to provide concrete, project-specific guidance.
