Grep a million GitHub repositories via MCP

This post details the integration of Grep's existing API with the Model Context Protocol (MCP), enabling AI applications to query a million public GitHub repositories via a standard HTTP interface. It provides configuration examples for AI clients like Cursor and Claude Code, and demonstrates how an AI agent can use the Grep MCP server to find code snippets related to error handling in MCP tool implementations. The integration was achieved using the `mcp-handler` package, abstracting boilerplate for schema, request routing, and response formatting.
