Frequently Asked Questions

Do I need ComfyUI running to search nodes?

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.

Where does the node catalog come from?

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.

What workflow JSON shape does ComfyUI expect?

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.

Use it from Claude, Cursor or ChatGPT

Same dataset, exposed as a Model Context Protocol server. Drop the URL into Claude Desktop, Cursor, VS Code, Cline, Windsurf, or any other MCP client.
