## MCP tools (3)

### `search_motion` (~85 tokens)

Find motion recipes by effect, use case, category, or stack. Returns compact matches; select an ID and call prepare_motion. No generation or network fetches.

Input parameters:

- `category` (string)
- `includeReferences` (boolean)
- `limit` (integer)
- `query` (string)
- `stack` (string)
- `verifiedOnly` (boolean)

### `get_motion` (~42 tokens)

Read a recipe prompt, dependencies, customization parameters, verification, source, and license. Source-only references return a link and no prompt.

Input parameters:

- `id` (string, required)

### `prepare_motion` (~65 tokens)

Prepare a motion prompt for the user coding agent using a recipe ID and project brief. Deterministic text preparation; does not render, call an LLM, or spend money.

Input parameters:

- `brief` (string, required)
- `customization` (object)
- `id` (string, required)
