Mcpdoc is an MCP server that provides controlled access to llms.txt documentation files for LLM applications like Cursor, Windsurf, and Claude. It exposes a `fetch_docs` tool that allows users to retrieve documentation URLs from user-defined llms.txt files while maintaining full auditability of tool calls and returned context. The server implements strict domain access controls to prevent unauthorized fetching of documentation from unintended domains.
