Verdicts

Popcraft MCP

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

Runway API

OpenAPI 3.1, llms.txt and Markdown copies of every docs page. Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog.

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.

Runway API

  1. Send X-Runway-Version: 2024-11-06 on every request or it fails
  2. Use the SDK's wait-for-output helper or poll GET /v1/tasks/{id} until SUCCEEDED or FAILED
  3. Don't retry a SAFETY.* failure unchanged. It's moderation, not an outage
  4. Take model IDs from the models page, not memory. Two were removed without notice on 2026-07-30
  5. Copy outputs to your own storage. URLs expire within 24 to 48 hours
