WHAT IT DOES

What geometry_boolean_union does on Flex Sensor Agent

AI agents invoke geometry_boolean_union to trigger actions in Flex Sensor Agent. 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 geometry_boolean_union needs a policy

Based on the tool name and server context, this likely performs a boolean union geometry operation within COMSOL, which is an Execute-level action (modifying simulation geometry/model state). The empty description reduces confidence. In COMSOL, boolean union merges geometric objects, which is a model-modification operation that could affect downstream simulation results.

From the tool's definition Tool name 'geometry_boolean_union' on a COMSOL Multiphysics simulation server; description is empty and uninformative.

Verdict

geometry_boolean_union Rate-limited

geometry_boolean_union stays usable, but rate-capped — a runaway agent can't fire it dozens of times 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 Flex Sensor Agent, so you can run agents against it safely.

FAQ

Questions about geometry_boolean_union

What does the geometry_boolean_union tool do? +

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

How do I enforce a policy on geometry_boolean_union? +

Register the Flex Sensor Agent MCP server in PolicyLayer and add a rule for geometry_boolean_union: 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 Flex Sensor Agent. Nothing to install.

What risk level is geometry_boolean_union? +

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

Can I rate-limit geometry_boolean_union? +

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

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

geometry_boolean_union is provided by the Flex Sensor Agent MCP server (tonghui666/flex-sensor-agent-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
