## Which one, for what

### sync. labs MCP server (D)

Good for: Agents that lip-sync or dub video into other languages.

Ahead on:
- Reliability, 43 against 35
- Schema & documentation, 81 against 48
- Security & auth, 38 against 28
- Payments & pricing, 30 against 20
- Maintenance & community, 75 against 57

Also in its favour:
- Open source

Watch for: No read-only mode

### Vidu API (E)

Good for: Batch jobs that can wait for off-peak prices and want reference-to-video or start-end frames with sound.

Also in its favour:
- Runs on your own machine

Watch for: No llms.txt, OpenAPI file or error-code reference


## Why the edge

### Schema & documentation: sync. labs MCP server +33

- sync. labs MCP server (81): Tools generated from the public API specification plus workflow tools, with typed schemas in the source (25). llms.txt and .md pages (10). Tool table with descriptions (14 of 20). Typed from the API spec (12 of 15). Examples and an estimates tool; errors not documented (8 of 15). Tags v0.2.2 to v0.2.4 and dated commits (12 of 15). 25 + 10 + 14 + 12 + 8 + 12 = 81.
- Vidu API (48): No OpenAPI file (0). No llms.txt or Markdown copies, though the HTML reference pages render without a browser (0). The image-to-video reference says what each model family is for (Q3 for synced audio and storyboards, Q2 for speed and quality, Q1 for clarity) (15). Typed parameters with model lists, per-model duration ranges (1 to 16 seconds on Q3), resolution options and defaults, though one `model` field carries nine values whose valid durations differ (13). We found no error-code reference, and examples rest on the listing's check (5). A dated update log, latest entry 15 September 2026 (15).

### Maintenance & community: sync. labs MCP server +18

- sync. labs MCP server (75): v0.2.4 and commits on 7 November 2026 (30). Three tags in recent weeks (20). Issues not read (0). Official registry entry io.github.synchronicity-labs/mcp-server (15). CI with verify, publish and review workflows (10). 30 + 20 + 0 + 15 + 10 = 75. Registry presence read from Anchor Terminal's own daily import of the official MCP registry (/api/v1/registry.json, 6 November 2026), not the registry's API.
- Vidu API (57): Model reading. The update log's latest entry, on 15 September 2026, adds the S2-Avatar real-time interactive model and the S2-Editing real-time editing model. viduq3-mix and other reference models arrived on 13 April (30). Q1 and Q2 stay callable, no removals found, no policy (10). Dated update page and support by email (12). No official SDK. A hosted MCP server is live, but the stdio package was last released on 24 June 2025 (5). The MCP repository has 5 stars and no recent release (0).

### Security & auth: sync. labs MCP server +10

- sync. labs MCP server (38): OAuth per organisation, or an API key in the environment (22 of 30). No read-only mode (3 of 20). Media in and out, no third-party text (10). No audit log found (0). No security programme found (3 of 20). 22 + 3 + 10 + 0 + 3 = 38.
- Vidu API (28): Model reading of the checklist (credential, training, retention, operator visibility, programme). One API key sent as `Authorization: Token`, no scopes found (20). The terms (effective 23 January 2025) let ShengShu examine, record, copy and use inputs and outputs for operational and other purposes, and don't rule out training (0). No retention period or deletion call found (0). Task list for per-task visibility, no audit log (8). No security.txt, bug bounty or certification found (0).

### Payments & pricing: sync. labs MCP server +10

- 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.
- Vidu API (20): No x402, MPP or L402 (0). Credit prices per second are published at $0.005 a credit, Q3 Turbo at 7 to 13 credits a second, with off-peak at about half (20). No free credits published (0). A person signs up and buys credits (0).

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

- 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.
- Vidu API (35): No status page found (0). No incident history to read (5). Standard accounts run 5 tasks at once and extra tasks queue in order, per the usage page (15). Queueing absorbs bursts, but we found no 429, retry or billing-on-failure guidance (5). No SLA (0). Q3 Pro and Q3 Turbo carry no preview label (10).

## Verdicts

**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.

**Vidu API.** Q3 Turbo from $0.035 a second at 540p, about half that off-peak. No llms.txt, OpenAPI file or error-code reference.

## Before you call either

### 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

### Vidu API

1. Send `Authorization: Token $VIDU_API_KEY`. The scheme is Token, not Bearer
2. POST the task, then poll the Get Creation endpoint by task id or set `callback_url`
3. Set `off_peak` only for jobs that can wait up to 48 hours. It roughly halves the credit rate
4. Set `audio` to true for dialogue and sound on Q3. It's off by default
5. Keep the AI-generated label on outputs. The terms forbid removing it
