This Rust library implements Anthropic's Model Context Protocol (MCP), providing a framework for AI assistants to connect with data sources and tools. It targets developers building AI-powered applications, offering a robust and efficient way to manage AI agent interactions with external resources.

How It Works

MCPR offers a schema-defined communication protocol with flexible transport layers, including stdio and Server-Sent Events (SSE). It provides high-level client and server abstractions, simplifying the creation of MCP-compatible applications. The library also includes CLI tools for generating project stubs and mock implementations for testing.

Quick Start & Requirements

• Install via Cargo: cargo install mcpr
• Add to Cargo.toml: mcpr = "0.2.3"
• Example usage and project generation commands are provided in the README.
• Official Demo: View Demo on Github

Highlighted Details

• Implements the full MCP schema.
• Supports stdio and SSE transport layers, with WebSocket planned.
• Includes CLI tools for project generation and stub creation.
• Provides mock transports for testing and development.

Maintenance & Community

• Version 0.2.0 was yanked; use 0.2.3 or later.
• Contribution guidelines are available.

Licensing & Compatibility

• Licensed under the MIT License.
• Compatible with commercial and closed-source applications.

Limitations & Caveats

• WebSocket transport is not yet implemented.
• Version 0.2.0 had critical SSE transport issues; ensure usage of 0.2.3+.
