comsol_connect · Flex Sensor Agent MCP: Risk & Policy

WHAT IT DOES

What comsol_connect does on Flex Sensor Agent

AI agents invoke comsol_connect 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 comsol_connect needs a policy

This tool initiates a network connection to an external COMSOL server, triggering an external operation. It is not merely reading data, but actively establishing a session/connection to a remote system, which falls under Execute. Misuse could expose the agent to unauthorized servers or consume remote resources.

comsol_connect Rate-limited

comsol_connect 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.

How do I enforce a policy on comsol_connect? +

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

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

Can I rate-limit comsol_connect? +

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

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

comsol_connect 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.
