What is the Model Context Protocol (MCP)?
MCP is an open standard developed by Anthropic that provides a structured way for AI applications to interact with external data, tools, and APIs without needing custom integrations for each tool.

Overview
What is LangGraph Agent with MCP?
This project integrates Model Context Protocol (MCP) with a LangGraph Agent, enabling the agent to dynamically access external tools, data sources, and APIs. It is designed for developers who want to build more modular and powerful AI systems with automatic tool discovery and multi-server support.
How to use LangGraph Agent with MCP?
Clone the repository, install dependencies from requirements.txt, and create a .env file with TAVILY_API_KEY and OPENAI_API_KEY. Run servers/server.py to start the MCP server, then run agent.py in a new terminal to connect the agent and execute queries.
Key features of LangGraph Agent with MCP
- Automatic tool discovery via MCP
- Multi‑server support (Tavily, YouTube transcript, math, weather)
- Predefined tools for web search and YouTube summarization
- Modular architecture – easily add additional MCP servers
- Connects LangGraph agents to external data and APIs
Use cases of LangGraph Agent with MCP
- Performing web searches through a LangGraph agent
- Summarizing YouTube video transcripts automatically
- Extending an AI agent with custom tools by adding new MCP servers
Frequently asked questions
What does this project integrate?
It integrates a LangGraph agent with MCP servers, allowing the agent to automatically discover and use external tools.
What dependencies are required?
A Tavily API key and an OpenAI API key must be set in a `.env` file. Python dependencies are listed in `requirements.txt`.
How do I start the system?
First run `servers/server.py` to start the MCP server, then in another terminal run `agent.py`. The agent will connect via the MCP client and execute your query.
What known limitations exist?
The README does not mention any specific limitations or security considerations for this project.
