Comfy docs (captured 2026-10-23): Comfy MCP has two connections. Cloud: remote MCP at https://cloud.comfy.org/mcp (OAuth sign-in or an API key header; new users get 5 free runs), recommended for claude.ai/ChatGPT/Claude Desktop and for Mac users running large open models; setup via Claude Desktop custom connector, `claude mcp add --transport http comfy-cloud https://cloud.comfy.org/mcp`, or a "comfy-cloud" plugin from the Comfy Skills repo; Cursor lacks MCP OAuth, so use an API key. Local: open-source first-party comfy-mcp server wrapping comfy-cli (>= 1.14.0) to drive a local or self-deployed ComfyUI from coding agents. Tools include node/model/template search, a CQL graph-query tool for structural questions, importing shared workflows from comfy.org/workflows URLs, and an opt-in anonymized session summary (agent must ask first). Practical: this is the vendor-supported alternative to ad-hoc creator MCP setups (C3-B346-02, C3-B365-01) and pairs with the Cloud REST/websocket API (C3-...
