Show HN: Open MCP Client (github.com)

Open-source & web based MCP client. Chat with any MCP server in your own app. Powered by CopilotKit & Composio.

Shipped this with cursor over the weekend and built: 1. The first web-based MCP client (deployed version on GH) 2. An open-source client you can add into any app.

Built using CopilotKit for the client and interactivity layer + agent frontend which connects to a LangGraph ReAct agent that coordinates MCP calls. Uses Composio's MCP server.
