# set_project

Replace the entire project with the given source JSON, returning its project_id. This is the PRIMARY way to build: use it to create a composition or to add/change many elements at once. (To tweak a single element in an existing project, use edit_element / add_element / delete_element instead.) Pass an existing project_id to replace that project; omit it to create a new one (note the returned id). The input is validated against the @clipkit/protocol before being accepted; invalid inputs return an error. Shape: { width, height, duration, frame_rate, output_format, background_color?, fonts?, camera?, lights?, elements:[…] }; every element has a type plus base fields (id, x, y, width, height, time, duration, track, opacity, rotation, animations, keyframe_animations) and type-specific fields. For exact field names + types call get_schema (optionally with an element_type) — the runtime ignores unrecognized keys, and this tool flags any it does not recognize.

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `source` | object | yes | A full Clipkit source object. |

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "set_project",
    "arguments": {
      "source": {}
    }
  }
}
```

## Why set_project is rated Medium

This tool creates or modifies data reversibly: it can replace an entire project (Write) or create a new one. While the description is cut off, the confirmed capability to 'Replace the entire project' and 'add/change many elements at once' clearly indicates data modification.

From the tool's own definition: "Tool description states 'Replace the entire project with the given source JSON' and 'use it to create a composition or to add/change many elements at once.' Key verbs: 'Replace' and 'add/change'."

## Use case

AI agents use set_project to create or update resources in Clipkit, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Clipkit environment.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Clipkit:
