Media Editor

A monorepo of MCP servers for AI-driven video editing, plus the shared media-analysis server they both rely on.

Packages

Package	Lang	What it is
packages/capcut-mcp	Python / uv	Edits CapCut drafts on disk (offline): clips, audio, text/captions, effects, filters, transitions.
packages/premiere-server	TypeScript	MCP server that drives Adobe Premiere Pro via a UXP plugin bridge.
packages/premiere-uxp-plugin	TypeScript	The UXP plugin loaded inside Premiere; the server talks to it over WebSocket.
packages/premiere-protocol	TypeScript	Shared message/types contract between the Premiere server and plugin.
packages/media-analysis	Python / uv	Editor-agnostic analysis: beat/energy detection, Whisper transcription, SRT, best-moments, stock fetch. Used by both editors.

Layout & tooling

Polyglot monorepo — unified by git, Claude skills, and one MCP config, not a single build:

• TypeScript (premiere-*) uses npm workspaces (root package.json). Build: npm install && npm run build.
• Python packages each keep their own uv venv — they are not a shared environment. media-analysis pulls Whisper/torch (heavy); capcut-mcp is light and must not inherit those deps.
• capcut-mcp does not import media-analysis; it calls it as a separate MCP server. The only coupling is registration in .mcp.json.

History & contribution model

capcut-mcp and the Premiere stack were each imported once via git subtree add (then restructured into packages/). This monorepo is the single source of truth — the full history of both originals is preserved here in main.

• Work on main. No subtrees, no submodules, no per-package branches.
• Do not run git subtree pull/push against the old standalone repos. The Premiere code was moved out of its original _pp/ prefix, so the prefixes no longer align and a sync would corrupt the tree. Treat the original capcut/premiere repos as archived.
• New work in any package is a normal commit here; there is nothing to sync upstream.

Setup

# TypeScript (Premiere) deps + build
npm install
npm run build

# Python servers — independent venvs (run once each)
uv sync --directory packages/capcut-mcp
uv sync --directory packages/media-analysis

# MCP registration: copy the template, add your Pexels/Pixabay keys
cp .mcp.json.example .mcp.json

Open Claude Code at this repo root so the relative paths in .mcp.json resolve. .mcp.json is gitignored (it holds API keys); share changes via .mcp.json.example.

Per-editor profiles (lighter context)

All three servers in .mcp.json load their tool schemas into every session (~12–18k tokens), but you never edit in CapCut and Premiere at once. Two slimmer profiles each load just one editor plus the shared media-analysis:

# CapCut session — skips Premiere's ~6–8k tokens of tool schemas
claude --strict-mcp-config --mcp-config .mcp.capcut.json

# Premiere session — skips CapCut's tool schemas
claude --strict-mcp-config --mcp-config .mcp.premiere.json

--strict-mcp-config makes Claude Code use only the named file, ignoring the default .mcp.json and user/global servers. Both profiles are gitignored (they hold API keys); copy the .mcp.capcut.json.example / .mcp.premiere.json.example templates and add your keys. Use plain .mcp.json (all servers) when you want everything loaded.
