MCP Server Toolkit
A Model Context Protocol (MCP) server that equips AI coding agents (Claude Code, Codex, Cursor, OpenCode, Gemini CLI) with filesystem, Git, database, and computation tools.
What is MCP?
The Model Context Protocol is an open standard that enables AI agents to securely interact with external tools and data sources. An MCP server speaks JSON-RPC 2.0 over stdio, exposing tools, resources, and prompts to any MCP-compatible client.
