TryMCP
Turn a JavaScript function into a live MCP server
TryMCP turns a few lines of JavaScript into a hosted MCP server that Claude, Cursor, VS Code and other AI apps can call. Write a tool in the browser, hit save, and get a live endpoint with auth, encrypted secrets, rate limits and logs. Free plan, no card.
Hey Product Hunt 👋
I'm Idris, one of the people behind TryMCP.
Over the last year, MCP became the way AI assistants like Claude, ChatGPT and Cursor use outside tools.
We loved the idea and kept running into the same wall. A tool that should take ten minutes to write turned into days of work: a server to host, OAuth to get right, secrets to store somewhere safe, and no easy way to see what the AI actually sent. So we built the platform we wanted to use. With TryMCP you:
1. Write a tool in JavaScript right in the browser
2. Press Run to test it with real inputs
3. Save it, and it's live at your-name.trymcp.io/mcp
4. Paste the generated config into Claude Desktop, Cursor, VS Code, Windsurf or Cline
Every server comes with four access modes (public, private link, API key or your own OAuth provider), encrypted secrets, per-minute rate limits and a full log of every call. Each call runs in its own sandbox, and tools can't reach private networks.
The free plan gives you 3 servers and 100,000 tool calls a month, with no credit card.
We're early, and we'd really value your feedback. What's the first tool you'd want your AI assistant to have?
I'll be here all day answering questions.
