## Why the edge

### Payments & pricing: sync. labs MCP server +15

- Magic Hour MCP (15): No machine payment protocol (0). Plan and credit-pack prices public, per-tool credit costs not read (10). 400 sign-up credits with no card, but API access sits on paid plans (5 of 20). A person signs up for a key in a browser (0). Tool discovery is open, but calls need a key (0). 0 + 10 + 5 + 0 = 15.
- sync. labs MCP server (30): No machine payment protocol (0). Per-second prices published (20). A free try for short videos (10 of 20). A person signs up (0). 0 + 20 + 10 + 0 = 30.

### Transparency & trust: Magic Hour MCP +14

- Magic Hour MCP (58): Closed service under terms naming Magic Hour AI, Inc., revised 3 October 2026 (15). The privacy policy says prompts, uploads and outputs aren't sold or used to train models, for free and paid accounts, and MCP requests are handled the same way; retention periods aren't given (20 of 30). No deprecation policy found (5 of 20). Subprocessors not read (10 of 20, model providers named in tool docs). 15 + 20 + 5 + 10 = 50.
- sync. labs MCP server (44): MIT open source (30). Data handling not read (5 of 30). No deprecation policy; earlier tool names documented as superseded (5 of 20). Subprocessors not found (0). 30 + 5 + 5 + 0 = 40.

### Reliability: sync. labs MCP server +8

- Magic Hour MCP (35): Status page at status.magichour.ai, all services online, with maintenance and previous incidents sections; no MCP component read (15). Incident history not read (5). No API rate limits found (0). No retry guidance found; wait_for_* tools poll long jobs (5 of 15). No SLA found (0). Not labelled beta (10). 15 + 5 + 0 + 5 + 0 + 10 = 35.
- sync. labs MCP server (43): Status page at status.sync.so with maintenance and previous incidents (20). History not read (5). No MCP limits found (0). The source has abort-signal handling and recovery guidance for long jobs (8 of 15). No SLA found (0). Version 0.2.4, not labelled beta (10). 20 + 5 + 0 + 8 + 0 + 10 = 43.

### Security & auth: Magic Hour MCP +7

- Magic Hour MCP (45): API keys as Bearer tokens or OAuth through the Claude and ChatGPT connectors (20 of 30). Destructive deletes are annotated; no read-only key (8 of 20). Tools return generated media, not third-party text (10). No audit log found (0). No security.txt or certifications found; face and voice tools come with policy limits in the terms (7 of 20). 20 + 8 + 10 + 0 + 7 = 45.

## Verdicts

**Magic Hour MCP.** Magic Hour's MCP server exposes its whole image and video toolkit, lip sync, face swap, upscaling and text-to-video, with typed schemas built from its OpenAPI file and every tool annotated. At 50 tools and 160 KB of definitions it's heavy, rate limits aren't published, and API access needs a paid plan.

**sync. labs MCP server.** sync. labs' MCP server is open source, generated from its API spec with workflow tools on top, and released often, with clear per-second prices for lip sync and dubbing. Security and data handling are thinly documented, and there's no read-only mode.

## Before you call either

### Magic Hour MCP

1. Call get_workflow_guide first to pick the right tool
2. Use the wait_for_* tools instead of polling project status yourself
3. Check credits with get_account_info before long video jobs
4. Only swap faces or voices of people who consented

### sync. labs MCP server

1. Get an estimate before long generations
2. Dub or lip-sync only voices and faces the user has the right to use
3. Check the active organisation before connecting with OAuth
