Comfy MCP (R1): connects external AI agents to ComfyUI over MCP to generate image/video/audio/3D, search models/nodes/templates and run real workflows. Two connections: a hosted Comfy Cloud server at cloud.comfy.org/mcp (OAuth; recommended for claude.ai, ChatGPT and Claude Desktop, added as a custom connector) and a local, fully open-source connection for people already running ComfyUI or working in coding agents (Claude Code via the comfy-cloud plugin from the Comfy-Org/comfy-skills marketplace, Cursor, Codex); both can run side by side with separate sign-ins. The docs advise Mac users wanting open-weight models such as MiniMax H3 or LTX-2.3 to use the cloud connection because those models are too large for practical speed on Apple GPUs. Comfy Agent (R2): in-app agent, generally available on Comfy Cloud (Desktop/local "coming soon", waitlist): finds templates/models/nodes, builds from a template, edits part of a graph while preserving the rest ("Keep the model and sampler settings"...

Comfy Agent (R2): in-app agent, generally available on Comfy Cloud (Desktop/local "coming soon", waitlist): finds templates/models/nodes, builds from a template, edits part of a graph while preserving the rest ("Keep the model and sampler settings"), validates before running, inspects images and media properties, runs workflows, supports plain-language personal skills and multiple concurrent chats. Cost: free starter tokens, then Comfy Credits at LLM Partner Node rates; the listed model is Opus 4.8 (input 1.055 credits/1K tokens, output 5.275/1K); workflows it runs cost the same as manual runs. Data (R3): messages, selected workflow/nodes, attachments and execution errors go through Comfy's online service even for a local install; cloud and local chat histories do not sync. Comfy Cloud (R4, R5): Blackwell RTX 6000 Pro 96 GB, 900+ pre-installed models, charged only for active GPU time, 30-minute job cap (1 h on Pro), queue up to 100 jobs; plans billed yearly Standard $16/month (50,400 credits/yr; ~4,560 five-second Wan 2.2 I2V clips by Comfy's estimate), Creator $28 (own models/LoRA import), Pro $80, Team $630 (up to 50 members, shared pool); every plan includes "Comfy API" builds/deployments/workers for serving workflows; top-up credits roll over up to 1 year. Practical: an agent (or a skill-equipped coding agent) can now drive production ComfyUI graphs; keep sensitive workflows local if the online-service data flow is a concern, and budget agent tokens separately from GPU time.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Docs and pricing pages only; no connection or run made. Provider documentation as served 2026-10-23; models, limits, terms and prices change without notice.

Limitations: Docs and pricing only; no connection or run made (no paid calls); credit-to-dollar conversion not shown on the pages read; "~videos per year" is Comfy's own estimate for a low-res 640x640 template; Comfy API deployment docs (openapi-cloud) not read; local MCP repo licence not checked.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
