Overview

What is MCP Rust CLI server template?

This template demonstrates how to implement a Model Context Protocol (MCP) CLI server in Rust. It provides a starting point for building MCP servers that can integrate LLM applications with external data sources and tools.

How to use MCP Rust CLI server template?

Clone the repository, modify project information in Cargo.toml and src/mcp/mod.rs, then edit the handler files (src/mcp/prompts.rs, src/mcp/resources.rs, src/mcp/tools.rs). Optionally modify JSON template files under src/mcp/templates/. Run the binary with --mcp to start the MCP server.

FAQ from MCP Rust CLI server template

What dependencies does the template require?

It is based on the JSON-RPC routing library rust-rpc-router. The project uses Cargo for dependency management.

How do I run the MCP server?

Use the --mcp CLI flag. Example: mcp-rs-template --mcp. Other flags include --resources, --prompts, and --tools for listing capabilities.

How do I configure it with Claude Desktop?

Edit claude_desktop_config.json in Claude Desktop (Settings > Developer > Edit Config) and add an entry in the mcpServers section with the command mcp-rs-template and arguments ["--mcp"]. Optionally set environment variables like API_KEY.

Where does the server data live?

Handlers and templates are stored in local source files: src/mcp/prompts.rs, src/mcp/resources.rs, src/mcp/tools.rs, and JSON templates under src/mcp/templates/.

What transport does the MCP server use?

The README describes a CLI-based invocation with the --mcp flag, which implies stdio transport (standard in/out) for communicating with MCP clients.

Frequently asked questions

What dependencies does the template require?

It is based on the JSON-RPC routing library [rust-rpc-router](https://github.com/jeremychone/rust-rpc-router). The project uses Cargo for dependency management.

How do I run the MCP server?

Use the `--mcp` CLI flag. Example: `mcp-rs-template --mcp`. Other flags include `--resources`, `--prompts`, and `--tools` for listing capabilities.

How do I configure it with Claude Desktop?

Edit `claude_desktop_config.json` in Claude Desktop (Settings > Developer > Edit Config) and add an entry in the `mcpServers` section with the command `mcp-rs-template` and arguments `["--mcp"]`. Optionally set environment variables like `API_KEY`.

Where does the server data live?

Handlers and templates are stored in local source files: `src/mcp/prompts.rs`, `src/mcp/resources.rs`, `src/mcp/tools.rs`, and JSON templates under `src/mcp/templates/`.
