Automations as MCP Tools
Publish one at /mcp for your agents and editor to call.
Automate with code where you need it.
Use a sandboxed TypeScript step for anything the integrations don’t cover. Publish an automation as an MCP server your agents and editor can call, build your own integration with the CLI, or use the REST API.
What you can extend it with.

“Connect apps, APIs and webhooks together to avoid menial tasks. It helps us do all of this at a much lower price.”
“The completely customizable and fluid builder is much better than Zapier. It took me under an hour to rebuild everything I had.”
“The modular way pieces are built, with MCP at its core, is genuinely how I see the future of the internet.”
“The visual designer is approachable for beginners but powerful enough for advanced users.”
“Once you get the hang of it, this thing is a powerhouse. It already handles the most critical automations in my daily operations.”
“As simple as Zapier but with the more advanced options of Make, and cheaper. That is my dream.”
“User-friendly, even for those without technical skills. Highly flexible and powerful, with options to add code when needed.”
“My experience has been nothing but positive. It stands out as not just an alternative, but in many ways a preferred choice.”
“The easiest and most user friendly automation software I have used. It was extremely easy to set up flows and get automations running.”
What engineers ask.
Yes. The CLI scaffolds and publishes an integration, action or trigger in TypeScript. Community integrations are open source on npm.
