About simple-mcp - MCP Project

What is simple-mcp - MCP Project: Hassle-Free & Lightweight Mastery?

simple-mcp is a streamlined MCP (Machine Communication Protocol) solution designed for developers seeking simplicity without sacrificing functionality. Unlike bloated frameworks, this project delivers a robust client-server architecture using standard I/O transport—all packed into an intuitive package that prioritizes ease of use over complexity. Whether you’re prototyping ideas or building production systems, simple-mcp ensures you spend less time wrestling with infrastructure and more time solving problems.

How to use simple-mcp - Hassle-Free & Lightweight Mastery?

First off, get started by cloning the repository and diving into the project structure. The workflow is straightforward:

Build the server: Navigate to the server directory and run cargo build to compile your first MCP service.
Launch the server: Execute cargo run to have it ready to accept connections.
Engage the client: Switch to the client folder and choose your mode—either interactive selection of tools or one-shot commands via CLI parameters.

For quick testing, simply run the provided test.sh script to see client-server communication in action. The “hello” tool demo illustrates how easy it is to greet a user by name through the protocol.

simple-mcp - MCP Project FAQ

FAQ from simple-mcp - Hassle-Free & Lightweight Mastery?

Q: Does it support other transport layers besides stdio?
A: Not yet, but the architecture is extensible. Contributions are welcome to add TCP/IP or WebSocket support!

Q: Can I customize logging levels?
A: Absolutely! Log granularity is configurable via environment variables, letting you toggle verbosity per deployment.

Q: How do I add my own tools?
A: Extend the server’s tools/ directory by creating Rust modules with handle() functions—no framework magic required.

Q: Is it cross-platform?
A: Built with Rust, it works on Linux/macOS/Windows out of the box. The stdio transport ensures compatibility across OSes.

Q: What’s the performance like?
A: Designed for simplicity first, but benchmarks show sub-millisecond latency for local processes—perfect for intra-application messaging.
