WHAT IT DOES

What physics_add_electrostatics does on Flex Sensor Agent

AI agents use physics_add_electrostatics 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_add_electrostatics needs a policy

The tool appears to modify simulation model configuration by adding a physics module (electrostatics), which is reversible within the COMSOL modeling workflow. This is a Write operation (model creation/modification) rather than Read, as it actively changes the simulation setup. It is not Destructive since COMSOL model edits are typically undoable/reversible.

From the tool's definition Tool name 'physics_add_electrostatics' suggests adding or configuring an electrostatics physics module to a COMSOL simulation model. The server context indicates building contact models and parameter sweeping for sensor simulation.

Verdict

physics_add_electrostatics Rate-limited

physics_add_electrostatics 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_add_electrostatics

What does the physics_add_electrostatics tool do? +

physics_add_electrostatics. 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_add_electrostatics? +

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

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

Can I rate-limit physics_add_electrostatics? +

Yes. Add a rate_limit block to the physics_add_electrostatics 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_add_electrostatics completely? +

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

physics_add_electrostatics 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.
