Comfy Cloud

Cancel a pending or running Comfy Cloud job by its `prompt_id`. Has no effect on a job that has already finished, and never deletes outputs already produced. Returns plain text saying which happened: a real cancellation, an already-finished no-op, or an unconfirmed cancel — relay that, do not assume the run stopped.

cancel_job

Estimate the credit cost of a Comfy Cloud template or workflow BEFORE running it. Read-only: nothing is submitted or spent. Pass exactly one of `template_name` (a template `name`; fetched server-side) or `workflow`. Prices come from the bundled node-catalog declarations and can lag live prices; GPU/queue time and storage are excluded. Full caveats ride on the result.

estimate_credits

Generate an image, video or audio clip with a partner provider model (Grok, Gemini, Flux, OpenAI, Kling, ByteDance, ElevenLabs, …) from a text prompt and optional input media. Diagrams/infographics are images. Pass the provider model slug (e.g. `bfl/flux-2-pro`); an unknown slug returns the closest real slugs. Returns `{prompt_id, status}` for a job whose result is saved to the library, or a direct download link for edits that cannot be saved. **Spend-gated**: call it WITHOUT `confirm` first — if it runs, done; if it returns a credit-spend prompt, relay it and re-call with `confirm: true` only on the user's explicit yes.

partner_generate

Return the Comfy Cloud feedback survey link. Use when the user offers or asks about feedback. Returns a short thank-you plus the survey URL — relay both verbatim. Records nothing beyond the fact that the link was shown; all feedback is given in the survey.

get_feedback_survey_link

Retrieve the outputs (images, videos, audio) of a completed Comfy Cloud job. Does not wait. Returns a no-auth download link (normally a `/api/s/<id>` shortlink) per file plus a browser-renderable inline URL where available; surface the link VERBATIM and never resolve it to the underlying signed URL. For PNG outputs it also reports pixel width/height. `inline_urls: false` skips the inline URLs.

get_output

Check the execution status of a submitted Comfy Cloud job by its `prompt_id` — a single point-in-time snapshot. Returns status: in_progress, completed, error, or cancelled, plus raw_status from the API (e.g. submitted, queued_limited, executing). On error/cancelled, `billed` is false if the job never started executing, else "unknown".

get_job_status

Get one saved workflow from the user's Comfy Cloud workspace by `workflow_id` (UUID or https://cloud.comfy.org/#<uuid> link) or `filename`. Read-only. Returns a node summary, the workflow JSON, its detected `format`, and a `customizable_inputs` breakdown of the per-run parameters (prompts, seeds, models, images) with the node id and input name each one is set through. `summary_only: true` returns a compact response without the full JSON.

get_saved_workflow

List the workflows saved in the user's Comfy Cloud workspace (cloud UI, comfy-cli, and MCP-saved). Each entry has a `filename` plus `workflow_id` and `version` (both `null` for legacy file-only entries); `filename_ambiguous: true` means that `filename` does not resolve to that row — use `workflow_id`. Paginated (default 20): while `has_more` is true, re-call with `offset: next_offset` to get the rest.

list_saved_workflows

Run a workflow saved in the user's Comfy Cloud workspace, identified by `filename` or `workflow_id`. The server fetches it, converts it and submits it; it never accepts raw workflow JSON. Only save-format (graph) workflows run here: a saved workflow whose `format` is `api` cannot be run on this connection. Optional per-run parameters: `input_overrides` ({nodeId: {inputName: value}}, the ids from the saved workflow's `customizable_inputs`) changes prompt, seed and similar inputs; `slot_overrides` sets subgraph-exposed slots by address (e.g. "57.text"). Returns a `prompt_id`. **Spend-gated when the workflow uses paid API nodes**: confirm the user agrees to spend credits, then re-call with `confirm: true`. `include_workflow: true` also echoes the converted workflow JSON.

run_saved_workflow

Fetch a Comfy Cloud template by name and submit it without loading the workflow JSON into context. Optional `prompt` sets its primary text input and `seed` sets its primary seed input — omit either to keep the template's own default; if the template has neither, passing one is rejected rather than silently ignored. Returns a prompt_id to poll (or one-shot, below). **Spend-gated when the template uses paid API nodes**: call it WITHOUT `confirm` first — if it runs, done; if it returns a prompt, relay it and re-call with `confirm: true` on an explicit yes. **One-shot**: `wait_for_output: true` (with `client_os`) waits inline (~25 s) and returns the finished output links, or `{status: "in_progress", timed_out: true}` if still running.
