WHAT IT DOES

What scpi_write does on Pypi:labmcp Alicat

AI agents invoke scpi_write 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 scpi_write is rated High

SCPI write commands directly control lab instruments, potentially causing unsafe hardware operations.

RECOMMENDED RULE

The rule that runs scpi_write 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 scpi_write, this is the rule to start with:

scpi_write Rate-limited

scpi_write 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.
