Open MCP Client
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.
Open MCP Client launched on March 10, 2025 with 6 votes and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.

We packaged an MCP server inside Chromium2025 · github.com · ▲46Hey HN, we just shipped a browser with an inbuilt MCP server! We're a YC startup (S24) building BrowserOS — an open‑source Chromium fork. We're a privacy‑first alternative to the new wave of AI browsers like Dia, Perplexity Comet. Since launching ~3 months ago, the #1 request has been to expose our browser as an MCP server. -- Google beat us to launch with chrome-devtools-mcp (solid product btw), which lets you build/debug web apps by connecting Chrome to coding assistants. But we wanted to take this a step further: we packaged the MCP server directly into our browser binary. That gives…
