Hey Product Hunt! 👋
Eight months ago we launched MCPCore here as a hosted way to run MCP servers. You told us the hosting was great, but writing every tool in code was still the hard part. Most people who want their AI agent to reach a real API or database are not going to write a server from scratch.
So today we are back with the biggest update since day one: the no-code workflow builder.
What you can do now:
🧩 Build tools on a canvas. Connect Start, HTTP Request, Database, Query, Transform, Condition, For Each and Return steps. Fill in a few fields and it becomes a live MCP tool.
🔁 Loops, retries and error branches built in. Decide what happens when a step fails: stop the tool or continue on an error branch.
📄 OpenAPI to MCP in one link. Paste an OpenAPI or Swagger URL, pick the endpoints, and each one becomes a workflow tool you can edit.
✨ Describe it, get a workflow. Write what the tool should do in plain words and AI drafts the workflow for you.
🧪 Playground. Chat with Claude or GPT using your own key and watch exactly which tools the model calls, with the parameters and results.
🔌 Easy to connect. Cursor and VS Code install with one click, Claude Desktop with a downloadable extension, and Claude Code, Codex and Gemini CLI with one command.
🕘 Versioning, like git for your tools. You asked for this one. Every save becomes a version. Work on a draft while the live version keeps serving your agents, compare it with the live version side by side and roll back with one click. A rollback is a new version too, so the history never loses anything.
Everything still runs on our managed infrastructure with HTTPS, four security modes (Public, Unlisted, API Key, OAuth 2.0), encrypted secrets, logs and analytics.
The free plan needs no credit card. I would love to hear what you build first, and what step type we should add next. I will be here all day answering questions.
