WHAT IT DOES

What switch_gauge_off does on Pypi:labmcp Alicat

AI agents invoke switch_gauge_off to trigger actions in Pypi:labmcp Alicat. 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.

RISK

Why switch_gauge_off is rated High

Toggles lab instrument state; misuse could disrupt vacuum systems or experiments.

From the tool's definition Switch an ionisation gauge off before venting or if pressure rising

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs switch_gauge_off safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Pypi:labmcp Alicat, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For switch_gauge_off, this is the rule to start with:

switch_gauge_off Rate-limited

switch_gauge_off 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.

Questions about switch_gauge_off

What does the switch_gauge_off tool do? +

Switch an ionisation gauge off (e.g. before venting, or if the pressure is rising). Always. It is categorised as a Execute tool in the Pypi:labmcp Alicat MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on switch_gauge_off? +

Register the Pypi:labmcp Alicat MCP server in PolicyLayer and add a rule for switch_gauge_off: 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 Pypi:labmcp Alicat. Nothing to install.

What risk level is switch_gauge_off? +

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

Can I rate-limit switch_gauge_off? +

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

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

switch_gauge_off is provided by the Pypi:labmcp Alicat MCP server (pypi:labmcp-alicat). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
