WHAT IT DOES

What light_set_led does on Tolpo

AI agents use light_set_led to create or update resources in Tolpo, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Tolpo environment.

RISK

Why light_set_led is rated Medium

An AI agent can call light_set_led faster than any human can review: one bad instruction and it creates or modifies resources in Tolpo by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs light_set_led safely

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

light_set_led Rate-limited

light_set_led 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.
