[maintain] [Publish]

This library provides a complete implementation of the Model Context Protocol (MCP) for Haskell. MCP is a protocol that enables seamless communication between AI models and external tools, resources, and services. This implementation supports the latest MCP protocol version (2025-06-18) with full compatibility for resources, tools, prompts, and all standard MCP message types. It provides both a server framework and type definitions for building MCP-compliant applications. . Features dual transport support: . * StdIO transport for process-based clients (e.g., Claude Desktop) * HTTP transport following the official MCP specification for web-based integration, and supports OAuth authentication. . Both transports use the same MCPServer typeclass, allowing seamless switching between communication methods while maintaining identical server logic.
