# Ark Seed Multimodal MCP > Seedance video, Seedream stills, and Seed Audio behind one typed BytePlus MCP server. - **Category:** Video Generation - **Vendor:** BytePlus SA program (byteplus-sa) — vendor-adjacent, not the ModelArk product team (community) - **Pricing:** paid - **Verified:** 2026-09-16 ## What it does A FastMCP server that fronts BytePlus ModelArk and Seed Speech: Seedance text- and image-to-video (including Seedance 2.5, which takes up to 30 reference images and 10 reference videos), Seedream image generation and editing, Seed Audio full-scene speech, ASR, video understanding, and the VOD AI MediaKit tools for enhancement, transcode, subtitle burn-in or removal, and voice/music/sfx separation. Every long job runs in the background — native MCP task augmentation where the client supports it, ordinary ark_job_* tools where it does not — and finished media is copied into a local artifact store, which matters because BytePlus output URLs expire after 2 hours for audio and 24 for image and video. The only route to Seedance in this directory, and the only one that also carries the finishing tools around it. ## Connect - Local: `Clone and run locally — git clone https://github.com/byteplus-sa/ark-mcp, then uv sync, then point the client at: uv --directory /path/to/ark-mcp run python -m ark_mcp (BytePlus keys go in the client's env block). No npm or PyPI package exists.` **Auth:** api_key (env `BYTEPLUS_MODELARK_API_KEY`) — — ModelArk > API Key covers Seedream and Seedance; Seed Speech and VOD AI MediaKit each issue a separate key, and the server only registers the tool groups whose keys you set ## Capabilities [text-to-video](https://mcp.film/capabilities/text-to-video.md) · [image-to-video](https://mcp.film/capabilities/image-to-video.md) · `video-reference` · [text-to-image](https://mcp.film/capabilities/text-to-image.md) · [image-editing](https://mcp.film/capabilities/image-editing.md) · [tts](https://mcp.film/capabilities/tts.md) · `speech-to-text` · [video-understanding](https://mcp.film/capabilities/video-understanding.md) · [video-enhancement](https://mcp.film/capabilities/video-enhancement.md) · [subtitles](https://mcp.film/capabilities/subtitles.md) · `audio-separation` · [async-jobs](https://mcp.film/capabilities/async-jobs.md) ## Sample tools `seedance_create_task` · `seedance_get_task` · `seedance_create_task_variations` · `seedream_generate_image` · `seedream_edit_image` · `seed_audio_generate` · `speech_to_text` · `seed_understand` · `vod_enhance_video` · `vod_separate_audio` · `media_upload` · `ark_job_submit` ## Field notes Read the vendor line carefully: byteplus-sa is BytePlus's solution-architect program org (created 16 May 2026, blog byteplus.com, four public repos), not the ModelArk product team, so this is listed as unofficial — the keys and the billing are first-party, the server is not. MIT by GitHub's licence detection, although the README's own licence section punts to 'project configuration'. It is young and unnoticed: 1 star, repo created 20 Jul 2026, last pushed 14 Sep 2026, no releases or tags and no published package, so a clone plus uv sync on Python 3.12+ is the only install and you get whatever main happens to be that day. Its own quality claims disagree with themselves — the feature list says 1,155 offline tests at 86% coverage, the status section says 631 at 88% — and we have not run it, so treat the polish as unverified. Three credentials, three auth schemes: ModelArk is Bearer, Seed Speech is X-Api-Key, VOD MediaKit is Bearer, and the default ModelArk host is region-scoped to ap-southeast, so accounts elsewhere must override BYTEPLUS_MODELARK_BASE_URL. The 3D tools (Hyper3D/Hitem3d) stay hidden unless you set BYTEPLUS_MODELARK_3D_ENABLED. The edge that will bite a filmmaker first: Seedance reference video must be a public HTTPS URL with no inline Base64 option, so you need TOS or S3 credentials for media_upload or your own hosting, and the server's SSRF policy rejects anything resolving to a private address. Model IDs are ModelArk endpoint strings you configure yourself (SEEDANCE_DEFAULT_MODEL, SEEDREAM_DEFAULT_MODEL), not friendly names. ## Verification - Status: Freshly checked (checked today) - Added: 2026-09-16 - Last verified: 2026-09-16 - Machine JSON: https://mcp.film/api/mcps/byteplus-ark.json ## Links - Site: https://docs.byteplus.com/en/docs/ModelArk/1520757?utm_source=mcp.film&utm_medium=referral&utm_campaign=directory&utm_content=byteplus-ark%3Asite - Docs: https://github.com/byteplus-sa/ark-mcp/blob/main/docs/getting-started.md?utm_source=mcp.film&utm_medium=referral&utm_campaign=directory&utm_content=byteplus-ark%3Adocs - Repo: https://github.com/byteplus-sa/ark-mcp --- Structured data: https://mcp.film/api/mcps/byteplus-ark.json · Directory: https://mcp.film Canonical: https://mcp.film/mcps/byteplus-ark/ Hosted directory MCP: https://mcp.film/mcp
