Features

  • Iterative refinement via regenerate (no re-prompting)

  • Explicit asset identity for reliable follow-ups

  • Job polling and cancellation for long-running generations

  • Optional image injection into the AI’s context (view_image)

  • Auto-discovered ComfyUI workflows with parameter exposure

  • Configurable defaults to avoid repeating common settings

Tools (18)

  • generate_image

    Generate images (requires prompt)

  • generate_song

    Generate audio (requires tags and lyrics)

  • regenerate

    Regenerate an existing asset with optional parameter overrides (requires asset_id)

  • view_image

    View generated images inline (images only, not audio/video)

  • get_queue_status

    Check ComfyUI queue state (running/pending jobs) - provides async awareness

  • get_job

    Poll job completion status by prompt_id - check if a job has finished

  • list_assets

    Browse recently generated assets - enables AI memory and iteration

  • get_asset_metadata

    Get full provenance and parameters for an asset - includes workflow history

  • cancel_job

    Cancel a queued or running job

  • get_defaults

    Get current default values

  • set_defaults

    Set default values (with optional persistence)

  • run_workflow

    Run any workflow with custom parameters

  • get_publish_info

    Show publish status (detected project root, publish dir, ComfyUI output root, and any missing setup)

  • set_comfyui_output_root

    Set ComfyUI output directory (recommended for Comfy Desktop / nonstandard installs; persisted across restarts)

  • publish_asset

    Publish a generated asset into the project's web directory with deterministic compression (default 600KB)

  • Session-scoped

    asset_ids are valid only for the current server session; restart invalidates them.

  • Manifest

    Updated only when manifest_key is provided.

  • Compression

    Deterministic ladder to meet size limits; fails with a clear error if it can't.
