Grpcurl is a command-line tool that lets you interact with gRPC services. This integration allows you to use Grpcurl via Model Context Protocol (MCP) for easier management and automation.

What are the key features of this Grpcurl MCP integration?

Key features include the ability to invoke gRPC methods with custom data, retrieve a list of all available gRPC services, and get detailed descriptions of gRPC services and message types using reflection.

What credentials does it need?

It reads `ADDRESS` from the environment. Store these in your client's env block or a secrets manager — never commit them to a repository — and grant the narrowest scope that still covers your use case.

What is the Grpcurl MCP Server?

Interacts with gRPC services using the grpcurl command-line tool via Model Context Protocol.

What it actually does

This project is an Model Context Protocol (MCP) server designed to interact with gRPC services using the grpcurl tool. It leverages the grpcurl command-line utility to perform various operations on gRPC services, such as invoking methods, listing services, and describing service details.

Invoke gRPC Methods — Use reflection to invoke gRPC methods with custom headers and JSON payloads
List gRPC Services — Retrieve a list of all available gRPC services on the target server
Describe gRPC Services — Get detailed descriptions of gRPC services or message types

Configuration

Go 1.23.0 or later - grpcurl tool installed on your system
