Use the same data from Claude, Cursor or ChatGPT. AI agents can call every tool the app uses.
Open Chat & MCPMCP for local ComfyUI: offline node catalog, draft validation, and GPU workflow execution through MCPBundles Desktop.
No. Searching nodes, templates, and validating drafts works from the materialized index. Queueing workflows and fetching images requires ComfyUI on your machine with Desktop connected.
MCPBundles indexes ComfyUI object_info from your local install (or a pinned snapshot) and refreshes on demand so agents query local evidence instead of live HTTP on every turn.
The HTTP API uses an API prompt map: node id strings to [class_type, inputs]. The knowledge tools document wires, output nodes, and common txt2img patterns.
