WHAT IT DOES

What fill_holes does on Blender Copilot MCP Server

AI agents use fill_holes 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.

RISK

Why fill_holes is rated Medium

The tool modifies mesh topology by filling detected holes—a reversible mesh editing operation. This is a Write action (modifies 3D geometry) rather than Destructive (no data is permanently lost, as the original mesh can be reverted or unfilled).

From the tool's definition Tool performs automatic filling of holes in mesh geometry, which modifies the mesh structure. Description states 'fill holes in a mesh...and filling,' indicating data modification rather than deletion or side-effect execution.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs fill_holes safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Blender Copilot MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For fill_holes, this is the rule to start with:

fill_holes Rate-limited

fill_holes stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about fill_holes

What does the fill_holes tool do? +

Automatically detect and fill holes in a mesh by selecting non-manifold edges and filling. It is categorised as a Write tool in the Blender Copilot MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on fill_holes? +

Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for fill_holes: 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 Blender Copilot MCP Server. Nothing to install.

What risk level is fill_holes? +

fill_holes is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit fill_holes? +

Yes. Add a rate_limit block to the fill_holes 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 fill_holes completely? +

Set action: deny in the PolicyLayer policy for fill_holes. 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.

What MCP server provides fill_holes? +

fill_holes is provided by the Blender Copilot MCP Server MCP server (dwgx/blender-copilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
