- Runway API: C 59.2, rank #714 of 1510 · https://www.anchorterminal.com/tools/runway.min.md
- sync. labs MCP server: D 51.5, rank #1026 of 1510 · https://www.anchorterminal.com/tools/sync-labs-mcp.min.md
- Runway API, 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, 67 against 43; Schema & documentation, 93 against 81; Agent ergonomics, 75 against 55; Security & auth, 51 against 38; Transparency & trust, 53 against 44.
- sync. labs MCP server, good for Agents that lip-sync or dub video into other languages. Ahead on Payments & pricing, 30 against 20; Maintenance & community, 75 against 62. Also Open source; No incidents deducted, where Runway API loses 3 points for them.

Why the edge:
- Reliability, Runway API +24: Runway API 67 (Atlassian Statuspage at status.runwayml.com with a Public API component and history pages back to June 2026 (20). From 5 August to 3 November the history lists 11 incidents. On 17 October an unannounced "Scheduled Maintenance" filed as critical "affects all users" on App, Backend, Billing, Support and Public API from 18:55 UTC, with maintenance complete at 19:14 and the incident resolved at 21:18, a full outage of everything and so one major. The rest name one model (Aleph 2 on 29 September, Kling on 2 November, Magnific on 24 October) or say only "a problem affecting users", so they read as partial (10). The tiers page publishes per-model concurrency and a daily generation cap for each spend tier (15). Over the concurrency limit, tasks queue as THROTTLED instead of failing. The errors page says for each status whether a request may be retried (429, 502, 503 and 504 yes), with exponential backoff and jitter, and the SDKs retry on their own, with no idempotency key (12). No SLA published for self-serve tiers (0). The API and its models are generally available (10). 20+10+15+12+0+10 = 67.); 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.)
- Agent ergonomics, Runway API +20: Runway API 75 (Tasks are small JSON objects with output URLs, and the official SDKs include a wait-for-output helper, so an agent needn't write a polling loop (25). Ratio, duration and model choice set output size. No task list endpoint found (10). Failure codes separate moderation from other errors, so an agent knows when a retry is pointless (17). No idempotency key. The docs say not to retry SAFETY failures unchanged (10). Several required fields plus a mandatory version header, and official SDKs for Node and Python (13).); sync. labs MCP server 55 (A generated catalogue filtered by client profile, curated for ChatGPT (15). Project history and estimates (12 of 20). Recovery tools; errors not documented (8 of 20). Annotations not read (5 of 20). OAuth or a key, npm package and library use (15). 15 + 12 + 8 + 5 + 15 = 55.)
- Security & auth, Runway API +13: Runway API 51 (Model reading of the checklist (credential, training, retention, operator visibility, programme). One bearer key per project from the developer portal. The hosted MCP server uses OAuth. No permission scopes found on keys (20). Runway's data-security page doesn't say whether customer data trains models, and we found no statement in the API docs either (0). Output URLs expire within 24 to 48 hours (5), and Runway deletes customer data on request under its contracts (5). No input retention period found (0). Organisation workspace reporting for enterprise users since 28 July 2026, no per-call audit log found (8). No security.txt and no public disclosure policy (0). A private, invitation-only bug bounty (3). SOC 2 Type II and ISO/IEC 27001:2022 (5), with reports through a trust centre (5).); 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.)
- Maintenance & community, sync. labs MCP server +13: Runway API 62 (Model reading. Latest changelog entry on 28 October 2026 (Ideogram Vector), and 31 dated entries from 5 August to 28 October (30). Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 30 July 2026 with no earlier notice in the public changelog, and no later retirement notice was found (0). Busy dated changelog and a support desk (12). Official SDKs on npm and PyPI, Node 4.24.0 and Python 5.24.0 on 23 October 2026 (15). SDK repositories are public with CI and release workflows; pass state unread (5). 30+0+12+15+5 = 62.); 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.)
- Schema & documentation, Runway API +12: Runway API 93 (OpenAPI 3.1 at docs.dev.runwayml.com/openapi.json (25). llms.txt, llms-full.txt and a Markdown copy of every page (10). Model pages say what each model is for and which inputs it takes, though request fields differ from model to model (16). Typed fields with fixed ratios and duration ranges per model (13). Examples in curl, Node and Python, and failure codes such as SAFETY.* documented with what they mean (14). A dated X-Runway-Version header and a dated changelog with 23 entries between July and September 2026 (15).); 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.)
- Payments & pricing, sync. labs MCP server +10: Runway API 20 (No x402, MPP or L402 (0). Per-second credit prices for every model are published at $0.01 a credit without a login, 12 credits a second for Gen-4.5 (20). No free generation credits, $10 minimum first purchase (0). A person signs up in the developer portal and buys credits (0).); 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.)
