WHAT IT DOES

What light_source does on Torch-to-Crown

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

RISK

Why light_source is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs light_source safely

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

light_source Rate-limited

light_source 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.
