# viewport_set_shading Set viewport shading mode. Agent View of the PolicyLayer registry record for `viewport_set_shading`. HTML page: https://policylayer.com/tools/dwgx-blender-copilot/viewport-set-shading ## Facts - Tool: `viewport_set_shading` - 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: Execute (High 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": "viewport_set_shading", "arguments": {} } } ``` ## Why viewport_set_shading is rated High This tool modifies the active viewport's shading mode in Blender (e.g., Solid, Material, Rendered, Wireframe). It is not a data read, nor does it create/modify scene data or delete anything. It executes an application-level state change in an external tool (Blender), making Execute the most appropriate category. Misuse has minimal blast radius as it only affects display, hence low severity. From the tool's own definition: "'Set viewport shading mode' — triggers a change in the Blender viewport rendering state, an external operation affecting the application UI." ## Use case AI agents invoke viewport_set_shading to trigger actions in Blender Copilot MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started. ## Recommended policy (PolicyLayer) Verdict: **Rate-limited**.
