About MCP Rust CLI server template
A Rust application template for building a command-line MCP server. It is intended for developers and provides editable handlers for tools, resources, and prompts, plus CLI options to inspect them.
Key features
- 01Implement an MCP CLI server in Rust
- 02Edit tool, resource, and prompt handlers
- 03Use JSON files for MCP definitions
- 04Display resources, prompts, or tools from the CLI
Use cases
- 01Start a Rust MCP server project
- 02Customize handlers for tools, resources, and prompts
MCP support
The template builds an MCP server that can be enabled with `--mcp`. The CLI can also display its resources, prompts, and tools.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.
Details
From the project READMEMCP 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?
- Clone the repository
- Modify project information in
Cargo.tomlandsrc/mcp/mod.rs - Modify server handlers:
src/mcp/prompts.rs: prompts handlerssrc/mcp/resources.rs: resources handlerssrc/mcp/tools.rs: tools handlers
- Modify
src/mcp/templates/*.jsonif you prefer to use json files for prompts, resources, and tools
mcp-rs-template is based on 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?
- Edit
claude_desktop_config.json: Claude Desktop ->Settings->Developer->Edit Config - Add the following configuration to the
serverssection:
{
"mcpServers": {
"current-time": {
"command": "mcp-rs-template",
"args": [
"--mcp"
],
"env": {
"API_KEY": "xxxx"
}
}
}
}

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
