Overview

What is MCP Rust CLI server template?

MCP Rust CLI server template is a Rust application template that demonstrates how to implement a Model Context Protocol (MCP) CLI server. It provides a standardized way for developers to connect LLM applications with external data sources and tools using the MCP open protocol, and is built on the rust-rpc-router JSON-RPC library.

How to use MCP Rust CLI server template?

Clone the repository, modify the 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) or the JSON templates in src/mcp/templates/. Run the binary with the --mcp flag to enable the MCP server; optional flags --resources, --prompts, and --tools display the corresponding registered items.

FAQ from MCP Rust CLI server template

What runtime dependencies does it require?

You need a Rust toolchain; the rust-rpc-router library is automatically included via Cargo.

How do I add custom tools or resources?

Modify the respective handler files (src/mcp/tools.rs, src/mcp/resources.rs) and optionally the corresponding JSON templates.

How can I integrate with Claude Desktop?

Edit claude_desktop_config.json to add the server with command "mcp-rs-template" and args ["--mcp"], along with any environment variables like API_KEY.

Are there any known limitations?

The README does not mention specific limitations; it is a template intended for demonstration and customization.

What transport or authentication does it support?

The template uses JSON‑RPC over stdio (CLI). Authentication can be provided via environment variables (e.g., API_KEY) as shown in the Claude Desktop configuration.
