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.

Key features of MCP Rust CLI server template

Implements an MCP CLI server in Rust.
Based on the JSON-RPC routing library rust-rpc-router.
Modular handler files for prompts, resources, and tools.
Supports CLI flags for testing and display.
Integrates with Claude Desktop via configuration file.
Provides JSON template files for customization.

Use cases of MCP Rust CLI server template

Building an AI‑powered IDE with custom tool integrations.
Enhancing chat interfaces with external data sources.
Creating custom AI workflows using the standardized MCP protocol.
Prototyping MCP servers quickly with a Rust template.

Frequently asked questions

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.
