RISK

Why create_beacon_signing_key is rated Medium

This tool creates and persists a new object (a signing key) which is a reversible Write operation. While signing keys are sensitive for authentication/integrity purposes, the action itself is not Destructive (keys can be revoked/regenerated) and does not execute arbitrary code or move money.

From the tool's definition Tool name 'create_beacon_signing_key' and description 'Create a new beacon signing key' indicate a creation action that modifies system state by adding a new cryptographic signing key to the AdButler system.

RECOMMENDED RULE

The rule that runs create_beacon_signing_key safely

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

create_beacon_signing_key Rate-limited

create_beacon_signing_key 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.
