WHAT IT DOES

What physics_configure_boundary does on Flex Sensor Agent

AI agents use physics_configure_boundary to create or update resources in Flex Sensor Agent — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Flex Sensor Agent environment.

WHY IT NEEDS A POLICY

Why physics_configure_boundary needs a policy

Based on the tool name and server context, this tool likely modifies/configures boundary conditions within a COMSOL simulation model — a Write operation. Without a description, confidence is reduced. Configuration of boundaries is reversible (can be reconfigured), so Write is more appropriate than Execute or Destructive.

From the tool's definition Tool name 'physics_configure_boundary' suggests configuring boundary conditions in a physics simulation context (COMSOL Multiphysics server). No description provided.

Verdict

physics_configure_boundary Rate-limited

physics_configure_boundary 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 Flex Sensor Agent, so you can run agents against it safely.

FAQ

Questions about physics_configure_boundary

What does the physics_configure_boundary tool do? +

physics_configure_boundary. It is categorised as a Write tool in the Flex Sensor Agent MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on physics_configure_boundary? +

Register the Flex Sensor Agent MCP server in PolicyLayer and add a rule for physics_configure_boundary: 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 physics_configure_boundary? +

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

Can I rate-limit physics_configure_boundary? +

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

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

physics_configure_boundary 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.
