Windmill is an open-source, self-hostable workflow engine and developer platform for building internal tools, automations, scripts, flows, and AI-agent integrations. It offers both a hosted cloud instance and self-hosted deployments.

3 integrations · MCP · REST · CLI

Windmill exposes a REST HTTP API with OpenAPI, a streamable HTTP MCP server, and the `wmill` CLI; developer authentication is primarily via Windmill user bearer tokens, with the HTTP API also accepting authenticated session cookies and MCP additionally supporting OAuth via its gateway URL.

Credentials

Windmill user API tokenbearer$ wmill user create-token

Acquired by the CLI — running wmill user create-token opens the auth flow and stores the credential.

Windmill authenticated web session cookiecompoundGet key ↗

Sign in to your Windmill instance in the web app at Windmill Cloud or your self-hosted instance. The OpenAPI spec advertises cookieAuth as an alternative to bearer auth for the API, but the docs scraped here do not name the cookie or explain programmatic acquisition; this is mainly the browser session credential.
