WHAT IT DOES

What boolean_operation does on Blender Copilot MCP Server

AI agents use boolean_operation 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 boolean_operation is rated Medium

This tool modifies mesh data in Blender by performing geometric operations that combine or alter existing objects. While the changes are technically reversible through undo, the operation directly alters 3D model geometry. This is categorized as Write rather than Execute because it targets specific mesh objects with predictable, geometry-focused outcomes rather than executing arbitrary code.

From the tool's definition Tool performs a boolean operation between two mesh objects. Boolean operations in 3D modeling (union, difference, intersection) modify mesh geometry by combining or subtracting shapes, creating new geometry structures.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs boolean_operation 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 boolean_operation, this is the rule to start with:

boolean_operation Rate-limited

boolean_operation 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Blender Copilot MCP Server, apply this rule, and every boolean_operation call is checked against it from then on.

FAQ

Questions about boolean_operation

What does the boolean_operation tool do? +

Perform a boolean operation between two mesh objects. 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 boolean_operation? +

Register the Blender Copilot MCP Server MCP server in PolicyLayer and add a rule for boolean_operation: 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 boolean_operation? +

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

Can I rate-limit boolean_operation? +

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

Set action: deny in the PolicyLayer policy for boolean_operation. 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 boolean_operation? +

boolean_operation 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.
