ref-tools/ref-tools-mcp
Helping coding agents never make mistakes working with public or private libraries without wasting the context window.
Implements an MCP server with two tools—semantic search and URL fetching—that intelligently filters documentation results based on session search history to return only the most contextually relevant sections, typically 5k tokens maximum. Uses adaptive multi-step search patterns where agents refine queries based on intermediate results, avoiding the token waste of traditional pagination and over-fetching. Designed for integration with Claude Code, Cursor, and OpenAI deep research, with both HTTP (recommended) and stdio transport options.
