- Implements MCP CLI server in Rust
- Uses JSON-RPC routing via rust-rpc-router
- Provides handlers for prompts, resources, and tools
- Supports JSON template files for configurations
- Includes CLI flags for listing resources, prompts, and tools
Setting up with Highlight
This MCP is not yet compatible with Highlight’s one-click setup. However, you can still use it with Highlight by following these steps:
- Download and install Highlight from highlightai.com/download
- Navigate to the plugins tab and select "Add Custom Plugin"
-
Configure the plugin with the settings below
Plugin Name
MCP Rust CLI server templateCommand (node, npx, python, etc.)Please refer to the README for specific instructions on how to obtain API keys or other required environment variables.
- Enable "Start Automatically" if you want the plugin to start when Highlight launches
From the repository
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.
Claude Desktop / Cursor
Paste into your MCP client config file to install this server.

=============================
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, 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:
{
"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.
