# snap_to_ground Snap an object's lowest point to Z=0 (the ground plane). Agent View of the PolicyLayer registry record for `snap_to_ground`. HTML page: https://policylayer.com/tools/dwgx-blender-copilot/snap-to-ground ## Facts - Tool: `snap_to_ground` - 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": "snap_to_ground", "arguments": {} } } ``` ## Why snap_to_ground is rated Medium This tool modifies object properties (spatial position) reversibly—the change can be undone or corrected by moving the object again. It does not delete data, execute arbitrary code, or trigger external operations. While it alters scene state, the modification is non-destructive and can be easily reverted, placing it in the Write category rather than Execute or Destructive. From the tool's own definition: "Tool description states it will 'Snap an object's lowest point to Z=0 (the ground plane)', which modifies the object's position/transformation in the Blender scene." ## Use case AI agents use snap_to_ground 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) Verdict: **Rate-limited**.
