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.
