Motion MCP

AI-native motion-video production over the Model Context Protocol. Ask Claude, ChatGPT, Pi or any MCP client for a video; Motion MCP spends frontier-model tokens only on taste and delegates everything else to cheap models and deterministic tools.

How it works

brief ─▶ Jev routing ─▶ creative direction (host Opus or internal Opus) ─▶ Motion IR
     ─▶ deterministic compiler / Pi scene workers ─▶ HyperFrames lint · check · contact sheet
     ─▶ Jev issue classification ─▶ cheap fix  or  bounded Opus critique
     ─▶ preview render ─▶ final render ─▶ FFmpeg finishing ─▶ MP4

• Claude Opus 5.5 is the creative director: concept, scene architecture, critique. It never writes HTML.

• Director modes are explicit: host-opus (the calling Claude supplies a creativeSpec, so Opus is not paid twice; supplying a spec selects this mode) or internal-opus (the server calls Opus via OpenRouter). A custom planner mode is reserved but not yet accepted.

• Jev makes bounded, structured routing decisions (TypeSafe → cheap LLM → rules).

• Motion IR is a renderer-neutral contract; HyperFrames is the first compiler target.

• Pi runs cheap coding models for custom scenes, fenced to the scene file it owns.

• Bring your own Claude. A workspace can store its own Anthropic API key in the dashboard and run the director, the critic or a sandboxed Claude Agent SDK scene worker on it; director and critic calls on that key cost no credits (ADR 0013).

Call motion_inspect first: it returns the director modes, the CreativeSpec JSON Schema and pricing.

Develop

Requirements: Node ≥ 22.19, pnpm 10, FFmpeg on PATH. Chrome for rendering is fetched on demand. The Claude scene worker also needs bubblewrap (bwrap) on Linux; see CLAUDE_* in .env.example.

pnpm install
cp .env.example .env
pnpm check        # lint + typecheck + unit tests (never calls paid models)
pnpm dev          # MCP server on http://localhost:8787/mcp
pnpm motion doctor
pnpm motion keys create --name laptop   # issue a workspace API key (printed once)
pnpm motion create --brief "30s launch video for a developer tool, editorial, restrained"
pnpm test:live    # optional: real OpenRouter / R2 calls, needs keys in .env

Docker: docker compose up --build (add --profile tunnel with CLOUDFLARE_TUNNEL_TOKEN for public ingress).
