Verdicts

Popcraft MCP

OAuth connector without copying API keys. Published tool inventories disagree.

Seedance on BytePlus ModelArk

The video task API documents limits, error codes and per-model parameters in detail, with callbacks, a filterable task list and API keys restrictable by model and IP address. No status page, OpenAPI file or free video quota was found, the newest models need a USD 30 balance, and BytePlus model services are not sold in the United States.

Before you call either

Popcraft MCP

  1. Preview credit cost and obtain approval before submitting paid generation.
  2. Discover the current tool list instead of assuming the advertised count.
  3. Poll the existing job rather than resubmitting a generation after a timeout.

Seedance on BytePlus ModelArk

  1. POST to /api/v3/contents/generations/tasks on ark.ap-southeast.bytepluses.com, then poll GET /contents/generations/tasks/{id} or pass callback_url. Callbacks need an answer within 5 seconds
  2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads
  3. Pass resolution, ratio and duration in the request body. Parameters appended to the prompt as --rs or --dur are weakly validated and may be ignored
  4. On Seedance 2.5 set omni_reference_task_type to edit or extend so constraint errors arrive at submission. With auto they arrive after the task leaves the queue
  5. Do not send reference images or video with real human faces to Seedance 2.5 or 2.0. Only a queued task can be cancelled with DELETE
