What you get

Ask your DSH agent, in plain language:

• 🎙️ Talking-head cleanup — "remove all filler words and awkward pauses" (transcript-based editing: the agent edits text, the timeline follows)
• ✂️ Highlight cuts — "make a 30s version about pricing", "keep the best take"
• 💬 Captions — styled, bilingual, word-level karaoke highlight
• 🎨 Motion graphics — generated from JSX code, or from ChatCut's template library
• 🔍 Zoom, transitions, LUTs, sound effects — from the built-in library
• 🖼️ AI generation — images (GPT Image), video (Seedance), music, TTS, voice clone
• 📤 Export — mp4 / audio / SRT / NLE XML (Premiere · DaVinci · FCP) / transparent-background MG ProRes

Everything lands on a real multi-track NLE timeline you can also edit by hand at chatcut.io — the agent and you share the same project, live.

Why this plugin

ChatCut officially ships plugins for Claude Code and Codex only. This project adapts it to DSH:

Official plugin	This adapter
MCP server (streamable-http + OAuth)	bridged via @deepseek-ai/dsh-mcp-client (stdio bridge)
claude mcp login handles OAuth	chatcut-login.mjs — standard PKCE + dynamic registration
Host keeps tokens fresh	chatcut-bridge.mjs auto-refreshes on 401 and persists tokens
15 craft skills (SKILL.md)	installed into $DSH_HOME/skills/ unchanged, plus a DSH host-adapter skill

Configure the token once. Never think about it again. The bridge refreshes the access token with the rotating refresh token and stores it locally (0600).

Quick start

Prereqs: a ChatCut account (free tier works), DSH Desktop, network access to api.chatcut.io.

git clone https://github.com/nigedazhima/dsh-plugin-chatcut.git
cd dsh-plugin-chatcut

1. Log in (one time) — opens your browser for ChatCut OAuth:

# macOS with DSH Desktop (no separate Node needed):
ELECTRON_RUN_AS_NODE=1 "/Applications/DSH Desktop.app/Contents/MacOS/DSH Desktop" scripts/chatcut-login.mjs
# or, with Node >= 18:
node scripts/chatcut-login.mjs

Tokens are written to scripts/.tokens.json (git-ignored, mode 0600).

2. Install the skills:

cp -R skills/chatcut "$HOME/Library/Application Support/dsh-desktop/harness/skills/"

3. Mount the MCP server — copy cordis-patch-example.yml into your $DSH_HOME/cordis.patch.yml, replacing <REPO> with this repo's absolute path.

4. Restart DSH Desktop. In a new session, ask: "list your mcp__chatcut__ tools" — you should see ~50 tools.

How it works

DSH agent ──(stdio MCP)── chatcut-bridge.mjs ──(streamable-http + Bearer)── api.chatcut.io
                              │
                              ├─ 401? → refresh_token → new access_token → persist
                              └─ .tokens.json (0600, git-ignored)

• The bridge reuses the official @modelcontextprotocol/sdk already bundled with DSH — zero npm installs on macOS.
• Skills are the official ChatCut craft skills (talking-head guide, motion graphics, captions, export, …) plus a thin DSH host-adapter that maps Claude-Code-isms (tool prefixes, login commands, browser panes) to DSH equivalents.
• Transcript-first editing: the killer workflow is read_script → edit a markdown file with strikethrough → apply_script. Deleting a sentence in text deletes it on the timeline.

Troubleshooting

Symptom	Cause / fix
No mcp__chatcut__* tools in session	Bridge failed to start — check $DSH_HOME harness log; usually missing .tokens.json (run login)
Bridge says refresh_token invalid	Re-run chatcut-login.mjs (one browser round)
api.chatcut.io timeouts	Region-dependent; set HTTPS_PROXY for the login script, and add it to the bridge env in the cordis patch
Tools listed but calls fail	Check you're signed into the same ChatCut account in the browser editor

Security notes

• No credentials ship with this repo. .tokens.json is created locally by you and git-ignored.
• The OAuth client is registered dynamically (RFC 7591); no shared client secrets.
• Token file is chmod 0600; refresh tokens rotate on every refresh.

License

GPL-3.0-only — same as the upstream ChatCut agent-plugin, from which the skills/chatcut/resources/ are redistributed unchanged.
