WHAT IT DOES

What cb_configure_thresholds does on Plugin Hub

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

Why cb_configure_thresholds is rated Medium

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

RECOMMENDED RULE

The rule that runs cb_configure_thresholds safely

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

cb_configure_thresholds Rate-limited

cb_configure_thresholds 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.
