MCP Rust CLI server template ============================= Model Context Protocol (MCP) is an open protocol that enables seamless integration between LLM applications and external data sources and tools. Whether you’re building an AI-powered IDE, enhancing a chat interface, or creating custom AI workflows, MCP provides a standardized way to connect LLMs with the context they need. mcp-rs-template is a simple application template that demonstrates how to implement MCP CLI server in Rust. # How to use template? 1. Clone the repository 2. Modify project information in `Cargo.toml` and `src/mcp/mod.rs` 3. Modify server handlers: - `src/mcp/prompts.rs`: prompts handlers - `src/mcp/resources.rs`: resources handlers - `src/mcp/tools.rs`: tools handlers 4. Modify `src/mcp/templates/*.json` if you prefer to use json files for prompts, resources, and tools mcp-rs-template is based on [rust-rpc-router](https://github.com/jeremychone/rust-rpc-router), a JSON-RPC routing library for Rust. # CLI options * `--mcp`: Enable MCP server * `--resources`: display resources * `--prompts`: display prompts * `--tools`: display tools # How to use MCP CLI server in Claude Desktop? 1. Edit `claude_desktop_config.json`: Claude Desktop -> `Settings` -> `Developer` -> `Edit Config` 2. Add the following configuration to the `servers` section: ```json { "mcpServers": { "current-time": { "command": "mcp-rs-template", "args": [ "--mcp" ], "env": { "API_KEY": "xxxx" } } } } ``` If you want to check MCP log, please use `tail -n 20 -f ~/Library/Logs/Claude/mcp*.log`. # References * MCP Specification: https://spec.modelcontextprotocol.io/ * Model Context Protocol (MCP): https://modelcontextprotocol.io/introduction * rpc-router: json-rpc routing library - https://github.com/jeremychone/rust-rpc-router/ * Zed context_server: https://github.com/zed-industries/zed/tree/main/crates/context_server
