Seedance on BytePlus ModelArk vs sync. labs MCP server

Seedance on BytePlus ModelArk 79

Per the 9 October check for the docs pages, not re-read on 4 November. Model reading of the checklist (credential, training, retention, operator visibility, programme). API keys belong to a resource project, can be limited to named model IDs or endpoints and to an IP allowlist, and can be disabled or deleted. No expiry or rotation setting was found (28). The service terms say BytePlus will not use customer data to train models unless the customer opts in, and the data processing page and training FAQ agree (20). Task records last 7 days and video URLs 24 hours, DELETE removes a finished task record, and content that triggers the filter is kept 180 days. No general retention period for inputs was found (10). Keys show a last-used time and billing per key, and the console has usage statistics. The inference security audit page says it applies only to Skylark models (8). The trust centre lists ISO 27001, SOC 2 and other certifications for BytePlus as a whole, and the Go SDK repository's SECURITY.md points to the ByteDance security centre and a bounty policy. No security.txt, and no disclosure policy on byteplus.com itself. The Go SDK's SECURITY.md was re-read in a clone on 4 November, and OSV holds no advisory for the Go, Python or Java packages (13).

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.

Seedance on BytePlus ModelArk 85

Per the 9 October check, not re-read on 4 November (docs.byteplus.com answered robots.txt with its app page). Create returns only a task ID, the task object is small, and callback_url posts each status change so an agent need not poll (25). The list call pages with page_num and page_size up to 500 and filters by status, task ID, model and service tier, and resolution, ratio and duration size the output (20). Error codes come with a meaning and a suggested fix. On Seedance 2.5 some constraint errors arrive only after the task leaves the queue unless omni_reference_task_type is set (17). No idempotency key was found. Only successful videos are charged, a queued task can be cancelled with DELETE and a running one cannot (8). Only model and content are required, and official SDKs exist for Python, Go and Java (15).

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.

Seedance on BytePlus ModelArk 65

Per the 9 October check, not re-read on 4 November (docs.byteplus.com answered robots.txt with its app page). Closed models under the Customer Agreement (effective 30 September 2026) and the Service Specific Terms, which are public and dated. The Go SDK is Apache-2.0. Two cited documents, the General Terms for AI Services and the ModelArk Terms, returned no text to our reader (15). The service terms, the ModelArk data processing page and the training FAQ agree that customer data is not used for training without opt-in. Filter-triggered content is kept 180 days, and no general retention period for inputs is stated. A Data Processing Addendum is incorporated, which we did not open (20). A deprecation policy with a 30 day minimum and dated timetables for each batch (18). Processing locations are named as Malaysia, Indonesia and the EU/EEA, and a sub-processor list effective 24 September 2026 promises 15 days' notice of changes, but it has no ModelArk row (14).

Per the 9 October check, not re-read on 4 November (docs.byteplus.com answered robots.txt with its app page). No OpenAPI or similar file was found. The reference pages link an API Explorer that is drawn by script, which we could not read (0). www.byteplus.com/llms.txt is a short site index, and docs.byteplus.com has no llms.txt or published Markdown twin (3). The create-task reference states which models accept each field, which input modes cannot be mixed, and when to use frames over duration or set omni_reference_task_type (17). Fields carry types, ranges, defaults and per-model values. content is a mixed array of text, image, video, audio and draft items, and a legacy mode reads parameters from the prompt text (13). cURL, Python and Java examples in the tutorial, and an error page of about 120 rows with HTTP status, code, message and meaning (15). A versioned /api/v3 path, dated model IDs, and pages for product updates, model releases, deprecations and an API schema notice. Product updates are dated by month only and stop at August 2026 (13).

Model reading. The last dated change that touches Seedance is the 8 September 2026 deprecation notice for seedance-1-5-pro-251215, 57 days before this check; Dreamina Seedance 2.5 shows "Updated Aug 7, 2026" in the ai.byteplus.com model catalogue on 4 November, with no newer Seedance model. The Go SDK tagged v0.10.0 to v0.19.0 between 29 September and 3 November, but none of them changes its content-generation package, last changed on 26 August, so they don't set recency for this listing (as groq-speech-to-text's SDK releases that don't touch audio). The create-task reference's 8 October page date records no change. 20, in place of 30 (cause time and correction). The deprecation policy promises at least 30 calendar days' notice. seedance-1-5-pro-251215 got 64 days, from 8 September to 11 November 2026, after about 11 months on sale and with no automatic migration, and a Seedance 1.0 lite model went in the May 2026 batch. The minimum is short (12 of 20). Monthly product updates, model release and deprecation pages, with support by console ticket and a Discord server we did not test, per the 9 October check (11 of 15). Current official SDKs for Python, Go and Java (15). The Go SDK is Apache-2.0 with a CI workflow and 19 tags since its 11 August import, the latest v0.19.0 on 3 November 2026. It is below 1.0 and replaced an older SDK that the docs still need for some APIs (7). 20+12+11+15+7 = 65.

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).

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.
