Overview

What is MCP Rust CLI server template?

MCP Rust CLI server template is a simple application template that demonstrates how to implement a Model Context Protocol (MCP) CLI server in Rust. MCP is an open protocol that enables seamless integration between LLM applications and external data sources and tools. This template is for developers building AI-powered IDEs, chat interfaces, or custom AI workflows using Rust.

How to use MCP Rust CLI server template?

Clone the repository, modify project information in Cargo.toml and src/mcp/mod.rs, then edit server handlers in src/mcp/prompts.rs, src/mcp/resources.rs, and src/mcp/tools.rs. Optionally modify JSON template files in src/mcp/templates/. Run with --mcp flag to enable the MCP server. For Claude Desktop integration, add a configuration entry to claude_desktop_config.json.

FAQ from MCP Rust CLI server template

What is the MCP Rust CLI server template?

It is a Rust application template that shows how to implement a CLI server using the Model Context Protocol, enabling LLMs to connect with external data and tools.

How do I install and run the server?

Clone the repository, modify the template as needed, then run the binary with the --mcp flag. The server can be used standalone or configured in Claude Desktop.

What are the runtime dependencies?

The template depends on the Rust ecosystem and the rust-rpc-router library. No other external runtime is required beyond standard Rust tooling.

How do I integrate with Claude Desktop?

Add a JSON entry to claude_desktop_config.json with the server command mcp-rs-template --mcp and any required environment variables like API_KEY. Logs can be checked with tail on the MCP log file.

Can I use JSON files for prompts, resources, and tools?

Yes, the template supports JSON templates in src/mcp/templates/*.json as an alternative to Rust handlers.
