Builds high-quality Model Context Protocol (MCP) servers to connect external APIs and services with LLMs.
The mcp-builder skill provides a comprehensive framework and standardized process for developing Model Context Protocol (MCP) servers in both Python and TypeScript. It guides users through deep research, implementation of core infrastructure, tool design with proper schema annotations, and the creation of robust evaluation suites to ensure LLMs can effectively utilize the server. This skill is essential for developers looking to extend Claude's capabilities by integrating custom external services with reliable, well-documented tools and actionable error handling.
