## Facts

- Tool: `anim_set_interpolation`
- Server: Blender Copilot MCP Server (`dwgx/blender-copilot`) — https://policylayer.com/tools/dwgx-blender-copilot.md
- Homepage: https://github.com/dwgx/blender-copilot
- Risk category: Write (Medium risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why anim_set_interpolation is rated Medium

This tool modifies animation data (interpolation settings for keyframes) reversibly without deleting or executing external operations. It falls under Write category since it changes object properties in a 3D scene. Severity is medium because incorrect interpolation changes could degrade animation quality or break workflows, but the effect is easily correctable via undo or re-setting the interpolation type.

From the tool's own definition: "Tool description states 'Set interpolation type for all keyframes on an object' — this modifies animation keyframe properties in Blender."

## Use case

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

## Recommended policy (PolicyLayer)

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
