Describe it
Say what you want automated. Whenever writes it as typed TypeScript. No SDK for you or your agent to learn.
The MCP built for agentic development
Build, test and deploy workflow automations on Whenever from the AI client you already work in. Your agent writes the workflow; Whenever runs it as code, on a webhook, a schedule or on demand.
Pick your client
The server address is the same everywhere. Only the place you paste it changes.
claude.ai and the Claude desktop app
- Open Settings, then Connectors.
- Choose Add custom connector.
- Paste the server URL and save.
the terminal
- Run this once. Add --scope user to register it for every project instead of this one.
the Cursor editor
- Open Settings, then MCP, then Add new MCP server.
- Or write the file yourself: Cursor reads ~/.cursor/mcp.json on start.
the Codex CLI
- Add the server to your Codex config, then start a new session.
a VS Code workspace
- Create this file in the workspace you want the server available in.
- VS Code picks it up and offers to start the server.
The whole loop, without leaving the chat
Test it
Run the workflow against real inputs and read exactly what it does, before any of it goes live.
Deploy it
Publish it on a webhook, a schedule, or on demand, with managed credentials handled for you. Every run after that executes the code, not the prompt that wrote it.
Point your client at it
Add the server once, then describe the automation you want and read the code it writes. Whenever’s AI building is free within weekly usage limits; you pay per run.
