Protoc Gen Rust Mcp

What is Protoc Gen Rust Mcp

protoc-gen-rust-mcp is a protoc plugin designed to generate Model-Context-Protocol (MCP) servers in Rust from protocol buffer specifications. It enables AI models to interact with existing gRPC codebases using natural language, facilitating rapid prototyping and leveraging LLM capabilities.

Use cases

Use cases for protoc-gen-rust-mcp include developing AI-driven applications that require quick server setups, enhancing existing gRPC services with MCP capabilities, and enabling natural language interactions with AI models.

How to use

To use protoc-gen-rust-mcp, ensure you have protoc version 3.20 or later installed. Then, you can run the plugin to generate MCP servers based on your protocol buffer definitions. Specific instructions for running and debugging the plugin will be provided in future updates.

Key features

Key features of protoc-gen-rust-mcp include seamless integration with existing gRPC applications, rapid server generation from protocol buffers, and the ability to leverage natural language for AI model interactions.

Where to use

protoc-gen-rust-mcp can be used in various fields such as AI development, where rapid prototyping of server capabilities is essential, and in applications that require integration with existing gRPC services.

protoc-gen-rust-mcp

This is a Topeka plugin for the protoc compiler that generates a model-context-protocol(MCP) server based on a protocol buffer definition. Conceptually, this allows an AI model to use existing gRPC codebases with natural language, allowing for rapid prototyping and usage of LLM capabilities for protobuf based codebases.

Prerequisites

• protoc 3.20 or later
  [TODO: add all prerequisites to successfully build and run the plugin]

Running the plugin

[TODO: add instructions to run the plugin]

Debugging the plugin

[TODO: add instructions to debug the plugin]

Testing the example

Install the example mcp-vibe server
[TODO: add instructions to run the project specific example server]
Add the mcp-vibe server to your mcp servers:

{
  "mcpServers": {
    "vibe": {
      "command": "mcp-vibe"
    }
  }
}

and run a client with above mcp server attached (eg. claude desktop)

Topeka

Topeka is an open source project that provides code-generators for Model-Context-Protocol (MCP).
It is designed to facilitate the usage of MCP seamlessly against existing gRPC based applications. This is done via
leveraging code generation using the protoc compiler and installing the relevant Topeka plugin.

The plugins follow Semantic Versioning and any plugin prior to 1.0.0 releases ARE still subject to breaking changes. Please note, this is
applied to the generated servers, not the plugins themselves, which do not provide public APIs. This project reserves the right to change how code generation is achieved,
while maintaining stable MCP server APIs.
