Released 2026-07-04. Host your own MCP server — a new top-level feature alongside Workflows, Agents, and Streams.
New
- MCP servers. Create an MCP, attach the platform-tool actions, data sheets, workflows, and agents you want to expose, and get a token-authed endpoint that external AI clients (Claude Desktop, Cursor, the MCP Inspector) connect to. They can list and call exactly what you attached — nothing else.
- Rotatable connection token. Each MCP has a single bearer token you copy into your client's config. Rotate it any time from the editor — the old token stops working immediately, on the next request.
- Copy-ready client config. The editor shows the endpoint URL and a ready-to-paste client configuration snippet, so connecting a new client is copy-and-go.
- Safe by default. Sensitive platform tools are never exposed unless an admin explicitly enables them for the MCP surface; data-sheet password/secured columns are never returned; and every tool call is metered against a per-day plan limit. Exposing a workflow or agent is flagged as high-privilege, since a client can then trigger everything it does.
This is FlowFn hosting an MCP server (the opposite of an agent calling an external MCP server, which already existed).
