MCP Rs Template

🚀 MCP Rust CLI Server Template

The 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-driven IDE, enhancing a chat interface, or creating custom AI workflows, MCP provides a standardized way to connect an LLM with its required context. The mcp-rs-template is a simple application template that demonstrates how to implement an MCP CLI server in Rust.

🚀 Quick Start

How to Use This Template?

1. Clone the repository.
2. Modify the project information in Cargo.toml and src/mcp/mod.rs.
3. Modify the server handlers:
   • src/mcp/prompts.rs: Prompt handler
   • src/mcp/resources.rs: Resource handler
   • src/mcp/tools.rs: Tool handler
4. If you prefer to use JSON files to handle prompts, resources, and tools, modify src/mcp/templates/*.json.

The mcp-rs-template is based on rust-rpc-router, a JSON-RPC routing library in Rust.

CLI Options

• --mcp: Enable the MCP server.
• --resources: Display resources.
• --prompts: Display prompts.
• --tools: Display tools.

How to Use the MCP CLI Server in Claude Desktop?

1. Edit claude_desktop_config.json: Claude Desktop -> Settings -> Developer -> Edit Configuration.
2. Add the following configuration to the servers section:

{
   "mcpServers": {
      "current-time": {
         "command": "mcp-rs-template",
         "args": [
            "--mcp"
         ],
         "env": {
            "API_KEY": "xxxx"
         }
      }
   }
}

If you want to check the MCP logs, use tail -n 20 -f ~/Library/Logs/Claude/mcp*.log.
