VectCutAPI (CapCut/Jianying MCP)

What it does

Open-source Python toolkit that writes CapCut International and Jianying draft files: create a draft, lay in video, audio, images, text, SRT subtitles, effects, stickers and video keyframes, then save a draft that opens in the editor for finishing. It ships both an HTTP API and a stdio MCP server, so an agent can pre-cut social verticals and captioned versions that an editor polishes in CapCut.

Connect

Local install: Multi-step, no published package: git clone https://github.com/sun-guannan/VectCutAPI, `pip install -r requirements.txt -r requirements-mcp.txt` on Python 3.10+, install FFmpeg, copy config.json.example to config.json, then point your client at `python3 mcp_server.py` with cwd and PYTHONPATH set to the repo.

Sample tools

Field notes

Apache-2.0, 2,252 stars, pushed 23 Sep 2026 — the actively maintained successor to the CapCutAPI code that the archived capcut-mcp entry copied. The MCP server exposes 11 tools; the README's install is clone-and-pip, nothing is on PyPI. A separate TypeScript wrapper in the repo's mcp-server/ folder talks to the HTTP API on port 9001, but its npm package is marked 'once published', so use the Python stdio server. Drafts target CapCut International or Jianying and still have to land in the app's drafts folder; draft formats change with app updates, so test against your installed version. VectCut also runs a hosted cloud editor at vectcut.com with preview and cloud render — its pricing and any hosted MCP endpoint were not verified here. ByteDance offers no official CapCut MCP. Docs are English and Chinese; the English README's MCP guide links are broken Google redirects, read MCP_Documentation_English.md in the repo directly.
