Windmill's MCP server now has one URL, /api/mcp, and serves the tools of an AI session. Claude, ChatGPT, Cursor or any MCP client can explore a workspace, write scripts, flows and apps as your drafts, test-run, diff and deploy them, and run what is deployed. The access chosen at sign-in or on the token decides which tools the client gets.
New features
- One URL, <base_url>/api/mcp: the client signs in and you choose its workspaces and access.
- Access levels: Build and run (default), Read and run, Read only, or Scripts and flows as tools, each listing the tools the client gets.
- A token reaches one workspace, several, or all of yours including ones you join later.
- Scripts, flows, apps and their settings are written as your drafts; tools return links to runs, draft editors and deployed items.
- Legacy MCP URLs keep serving existing tokens.
