Ref MCP
Supports UIby ref-tools
Token-efficient documentation search and retrieval for AI coding agents to prevent context rot.
What it does
Ref MCP connects your AI coding agent to technical documentation for APIs, services, and libraries. It focuses on minimizing token usage to prevent 'context rot', ensuring the model stays sharp by providing only the most relevant snippets of documentation rather than massive page dumps.
Tools
ref_search_documentation: Performs a powerful search across public web docs, GitHub, and private resources to find specific facts or code snippets.ref_read_url: Fetches content from a specific URL and converts it to optimized markdown for the agent to consume.
