Model Context Protocol (MCP) Binary for rust-analyzer

[yogevm15]

Overview

With the growing adoption of the Model Context Protocol (MCP) as a standard for enabling AI assistants to interact with codebases and development tools, integrating MCP support into rust-analyzer could enhance its capabilities. This integration would allow rust-analyzer to serve as a backend for AI-driven code assistance tools, facilitating tasks like symbol resolution, diagnostics, and code navigation.

Motivation

MCP provides a structured protocol for AI assistants to communicate with various tools and services. By implementing an MCP-compatible binary, rust-analyzer can expose its rich language analysis features to AI models, enabling more intelligent code assistance. This integration aligns with the trend of enhancing developer tools with AI capabilities.

Potential Benefits

• Enhanced AI Integration: Facilitates the development of AI-powered tools that can provide intelligent code assistance for Rust projects.

• Improved Developer Experience: Enables features like natural language code queries, automated refactoring suggestions, and context-aware code generation.

I don't think it's the job of rust-analyzer to implement an interface for LLMs, nor I see other language servers doing that. We also expose an API (the ra_ap_X crates), so anyone feeling it's important can do it themselves.

Why not a generic MCP server for LSP?
