geometry_import · Flex Sensor Agent MCP: Risk & Policy

WHAT IT DOES

What geometry_import does on Flex Sensor Agent

AI agents use geometry_import 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 geometry_import needs a policy

Geometry import creates/modifies simulation data structures (model geometry) reversibly rather than executing arbitrary operations or deleting data. While the description is absent, the context of a COMSOL simulation server and sibling tools like 'flex_sensor_build_contact_model' suggest this tool populates or updates simulation geometry, classifying it as Write.

From the tool's definition Tool name 'geometry_import' and server context (COMSOL Multiphysics simulation platform) indicate the tool imports geometry data into a simulation model, which creates or modifies simulation state. Description is empty, lowering confidence.

Verdict

geometry_import Rate-limited

geometry_import 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 geometry_import

What does the geometry_import tool do? +

geometry_import. 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 geometry_import? +

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

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

Can I rate-limit geometry_import? +

Yes. Add a rate_limit block to the geometry_import 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_import completely? +

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

geometry_import 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.
