boolean_op · 3D MCP Server MCP: Risk & Policy

WHAT IT DOES

What boolean_op does on 3D MCP Server

AI agents use boolean_op to create or update resources in 3D MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 3D MCP Server environment.

WHY IT NEEDS A POLICY

Why boolean_op needs a policy

Boolean operations modify the 3D scene by combining existing objects into new ones. This is a reversible modification to the model (objects can be recreated), so it fits Write. It does not execute arbitrary code, delete data irreversibly, or involve financial transactions. The blast radius is medium since misuse could alter the model structure but the scene can be reconstructed.

Verdict

boolean_op Rate-limited

boolean_op 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.

PolicyLayer is an MCP gateway: every tool call is checked against your rule before it reaches 3D MCP Server, so you can run agents against it safely.

FAQ

Questions about boolean_op

What does the boolean_op tool do? +

Combine objects with boolean operations (union, difference, intersection). It is categorised as a Write tool in the 3D 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_op? +

Register the 3D MCP Server MCP server in PolicyLayer and add a rule for boolean_op: 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 3D MCP Server. Nothing to install.

What risk level is boolean_op? +

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

Can I rate-limit boolean_op? +

Yes. Add a rate_limit block to the boolean_op 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_op completely? +

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

boolean_op is provided by the 3D MCP Server MCP server (jagjerez-org/3d-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
