Overview ¶
Package mcp implements a Model Context Protocol server that exposes DevClaw tools, resources, and prompts to MCP-compatible clients (Cursor, VSCode, etc.) via stdio and SSE transports.
Package mcp – sse.go implements the SSE (Server-Sent Events) transport for the MCP server, allowing HTTP-based clients to connect.
