Generate Image

Generate and edit images with RunComfy

Use the connected RunComfy MCP tools. The client may prefix tool names with the plugin/server name. If disconnected, direct the user to the client's RunComfy authentication control. Never request an API token in chat or add one to a file.

Choose and review

1. Establish the subject, intended use, dimensions, number of images and any reference images. Reuse details already provided.
2. Use list_models with a targeted search and category such as text-to-image or image-to-image. Use list_model_categories if unsure of a category. Start with a small page and paginate when needed.
3. Match the user's requested model family. Examples available through RunComfy include FLUX 2, Seedream 5.0 and Nano Banana 2. Use the actual returned model_id; do not construct version strings or assume a similarly named endpoint supports edits.
4. Call get_model for the selected ID. Read current input schema, required inputs, enums, defaults, pricing unit and output type. Do not reuse another model's field names or hard-code remembered prices.
5. Check get_balance before paid work. Present the model, final prompt, reference inputs, dimensions/count and available cost estimate. Proceed within the user's existing authorization and spending limit; ask only when scope or cost is missing or changed. Explain when pricing is an estimate.

Run and retrieve

• For a file input, use an HTTPS URL accessible to the model service. A local path, browser-only blob: URL or authenticated gallery page is not a usable input URL. Do not publish a private image without authorization; if no supported upload route is available, explain what input is needed.
• Call run_model once with model_id, schema-valid inputs and wait_for_completion: false. Record the returned request ID.
• Poll get_model_request_status for that same ID with reasonable spacing. Retrieve get_model_request_result when finished. Use cancel_model_request only when the user requested cancellation or an agreed stop condition is reached.
• Inspect the cancellation outcome: a running or finished job may be not_cancellable. A cancellation attempt is not proof the job stopped or that charges ended. Reconcile status/results and report this limitation; a monitoring deadline is not a guaranteed spending cap.
• A timeout or interrupted response does not prove submission failed. Recover the existing request before considering a new paid call. Never silently submit a replacement or switch models.
• Return the actual output URL and request ID. Display the image when supported; otherwise provide a direct link. Say whether pixels were inspected. A returned URL is not proof that the image rendered correctly.
• Keep planned settings, returned settings and observed output properties separate. If the server fails or a result is unavailable, report the actual status and next recovery step.

Useful requests

• “Compare current FLUX and Seedream image options for one square product image. Show inputs and price before running.”
• “Edit this image to change only the background, using a supported image-editing model. Keep the product unchanged.”
