shrinkwrap_reproject · Blender MCP: Risk & Policy

WHAT IT DOES

What shrinkwrap_reproject does on BlenderMCP

AI agents invoke shrinkwrap_reproject to trigger actions in BlenderMCP. 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.

WHY IT NEEDS A POLICY

Why shrinkwrap_reproject needs a policy

Based on the tool name and server context (BlenderMCP for 3D modeling), this tool likely reprojects geometry onto a surface using a shrinkwrap operation in Blender, which would involve executing a Blender operation that modifies mesh data. However, since the description is empty, confidence is low.

From the tool's definition Tool name: 'shrinkwrap_reproject'; description is empty/uninformative.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches BlenderMCP, so you can run agents against it safely.

FAQ

Questions about shrinkwrap_reproject

What does the shrinkwrap_reproject tool do? +

shrinkwrap_reproject. It is categorised as a Execute tool in the BlenderMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

Register the Blender MCP server in PolicyLayer and add a rule for shrinkwrap_reproject: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches BlenderMCP. Nothing to install.

What risk level is shrinkwrap_reproject? +

shrinkwrap_reproject is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit shrinkwrap_reproject? +

Yes. Add a rate_limit block to the shrinkwrap_reproject rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block shrinkwrap_reproject completely? +

Set action: deny in the PolicyLayer policy for shrinkwrap_reproject. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
