tiktok-studio-mcp

MCP server for TikTok. Publishes videos to your own TikTok account and reads back how they performed, through TikTok's official Content Posting and Display APIs.

Built as the TikTok counterpart to yt-studio-mcp.

What it can and cannot do

TikTok's creator APIs are narrower than YouTube's. Rather than advertise tools that cannot work, this server exposes only what the platform actually supports:

Posting modes

TikTok gates direct publishing behind an app audit, so there are two modes, selected with TIKTOK_MCP_MODE:

• upload (default) — the video lands in your TikTok inbox/drafts and you finish posting it in the app. Works without an audit.

• publish — posts directly. Requires the video.publish scope, which needs TikTok's full app audit (2–4 weeks, demo video, privacy policy, domain verification).

Until the app is audited, TikTok forces everything an unaudited client posts to private, whatever privacy_level you ask for. post_video says so in its result rather than letting you assume something published.

Install

claude mcp add tiktok -s user -- uvx tiktok-studio-mcp

Authenticate

Register an app at developers.tiktok.com with Login Kit, Content Posting API and Display API, requesting the scopes user.info.basic, video.upload, video.list, video.publish. Set the Desktop redirect URI to http://localhost:8902/.

export TIKTOK_MCP_CLIENT_KEY=...
export TIKTOK_MCP_CLIENT_SECRET=...
tiktok-studio-mcp auth

Prefer the environment over --client-key / --client-secret: command-line arguments are visible to any user on the box via ps and land in shell history. The flags still work as a fallback.

The flow is headless-friendly: it binds a fixed port and prints the consent URL rather than launching a browser. On a machine with a browser:

ssh -N -L 8902:localhost:8902 user@your-host

then open the printed URL.

Tools

post_video calls creator_info first and validates privacy_level against what the account actually allows, because TikTok rejects mismatches with an unhelpful error.

Secrets

TIKTOK_MCP_SECRETS selects the backend: file (default, ~/.config/tiktok-studio-mcp/credentials.json, mode 600), env, or vaultproxy.

TikTok rotates refresh tokens — every refresh returns a new one and invalidates the old. This server writes the new token back on every refresh; if it did not, authentication would work for 24 hours and then fail with no obvious cause.

Limits

Enforced by TikTok, surfaced by this server:

• 6 requests per minute per access token on the init endpoints

• 5 pending shares per 24 hours

• chunked upload: files under 5 MB go whole; otherwise chunks are 5–64 MB, the final chunk may reach 128 MB, 1–1000 chunks, 4 GB maximum

Development

pip install -e '.[dev]'
ruff check src tests
pytest

Tests use an injected transport and need no TikTok credentials.
