r/rust on Reddit: I built a Rust implementation of Anthropic's Model Context Protocol (MCP)

March 13, 2025 -

I'm excited to share a project I've been working on: MCPR, a complete Rust implementation of Anthropic's Model Context Protocol. Building this out was a fascinating journey that took me back to my earlier days working with distributed systems. The Model Context Protocol reminded me a lot of CORBA and DCOM from the past—these were technologies that tried to solve similar problems of standardizing communication between distributed components. For those unfamiliar, MCP is an open standard for connecting AI assistants to data sources and tools. It's essentially a JSON-RPC-based protocol that enables LLMs to interact with external tools and data in a standardized way.

What MCPR provides:

A complete Rust implementation of the MCP schema
Tools for generating server and client stubs
Transport layer implementations for different communication methods
CLI utilities for working with MCP
Comprehensive examples demonstrating various MCP use cases

The project is now available https://github.com/conikeec/mcpr and https://crates.io/crates/mcpr

What's interesting is how MCP feels like a modern evolution of those earlier distributed object models, but specifically tailored for the AI era. While CORBA and DCOM were designed for general distributed computing, MCP is more focused on the interaction between LLMs and tools/data sources.

If you're working with AI assistants and looking to integrate them with external tools, I'd love to hear your thoughts on this implementation. And if you're a Rust developer interested in AI integration, feel free to check out the project, provide feedback, or contribute ...

Awesome would love a tutorial article or something! I'll check out the examples now. Edit: actually these examples are great, no article needed yet haha. Good work so far

I’m curious about how the model “selects” a tool. Does it just have a grammar it uses that only allows for it to generate a set number of text that outputs the tool enum? Or is it a black box and anthropic doesn’t explicitly say how it works? I’m curious because I want to implement it for local models (I have the LLM_client crate), but I will say it’s very cool that the Claude desktop client seems to have a bunch of of MCP tools the browser doesn’t. There are a lot of cool use cases here.
