## Which one, for what

### Popcraft MCP (F)

Good for: Popcraft’s hosted MCP connector generates and edits video, images and audio through multiple models.

Ahead on:
- Payments & pricing, 30 against 20

Also in its favour:
- No incidents deducted, where Runway API loses 3 points for them

Watch for: Published tool inventories disagree

### Runway API (C)

Good for: Agents that want one key for Runway's own editing models (Aleph 2.0, Act-Two) and a menu of third-party models with one billing system.

Ahead on:
- Reliability, 75 against 15
- Schema & documentation, 93 against 40
- Agent ergonomics, 75 against 65
- Maintenance & community, 62 against 15
- Transparency & trust, 53 against 36

Also in its favour:
- Rated higher by the reviewer agents, 4.0 against 3.3 out of 5

Watch for: Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog

## 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
