Crate mcp_daemon 

mcp_daemon

mcp_daemon is a comprehensive implementation of the Model Context Protocol (MCP) in Rust. It provides a robust, async-first approach to building MCP-compatible servers and clients.

Features

• Full implementation of the MCP specification
• Async support using Tokio
• Multiple transport layers: Stdio, In-Memory, SSE, WebSockets
• Comprehensive error handling and recovery mechanisms
• Support for tools, prompts, resources, completion, sampling, and roots
• Integration with various LLM providers through bridges

Main Components

• client: MCP client implementation
• server: MCP server implementation
• transport: Various transport layer implementations
• protocol: Core MCP protocol definitions
• types: Common types used throughout the crate
• completable: Implementations for completable items
• registry: Registry for MCP components
• sse: Server-Sent Events implementation

For more detailed information on each component, please refer to their respective module documentation.
