Integrate source code API extraction into automated workflows via MCP JSON-RPC.

sig is a tool that extracts the public API surface from source files, including function signatures, type/struct/interface definitions, and const/var blocks, without including implementation bodies. It supports Go, TypeScript, and C# languages. The tool can be used via CLI or as an MCP JSON-RPC stdio server, making it easy to integrate with other tools like Claude Code. This helps developers quickly analyze and document code APIs in a structured JSON format.
