grpc-invoke-mcp is an MCP server for calling gRPC methods from AI agents like Claude Code, Codex, Cursor, and other MCP-compatible tools.
It gives agents a simple way to inspect gRPC APIs and invoke unary RPCs using either server reflection or local .proto files. This is useful when you want an agent to explore services, understand request and response schemas, make real gRPC calls, and test gRPC integrations during agent-driven development without writing one-off scripts.
