🤖 Agent Tools & MCP Servers Hub

A curated, plug-and-play collection of AI Agent Tools, Model Context Protocol (MCP) servers, and integration connectors for modern AI agents (LangChain, CrewAI, AutoGen, OpenAI Swarm).

🌟 Why This Repo?

Building AI agents requires connecting them to real-world APIs, tools, and databases. This repository provides:

🧩 Zero-conflict Modular Tools: Every tool lives in its own standalone directory (tools/<tool-name>/).
⚡ Multi-Language Support: Implementations in Python, TypeScript/Node.js, or Go.
🔌 Universal Compatibility: Compatible with Model Context Protocol (MCP), OpenAI Function Calling, and LangChain Tools.
🤝 Beginner-Friendly Open Source: Ideal for first-time and seasoned contributors alike.
