## What it is
An open-source MCP (Model Context Protocol) client starter built with a Next.js frontend and a Python LangGraph agent backend, using CopilotKit to connect chat interfaces to MCP servers. It serves as a reference application for building custom AI agent frontends that talk to MCP tools.

## Use cases
- build a custom chat UI that connects to MCP servers
- create an open-source MCP client for my AI agent
- connect LangGraph agents to MCP tools
- self-host a web interface for Model Context Protocol servers
- starter template for CopilotKit agent apps
- test and interact with MCP tools from a browser

## When to choose
- you want a ready-made open-source MCP client with a chat frontend
- you're building with CopilotKit and LangGraph and need MCP integration
- you need a self-hosted web UI to interact with MCP servers

## When to avoid
- you need a lightweight CLI or desktop MCP client rather than a web app
- you don't want to run separate Python agent and Node.js frontend services
- you need a production-hardened product rather than a starter template
