WHAT IT DOES

What redis_setup_pubsub does on Plugin Hub

AI agents use redis_setup_pubsub 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.

RISK

Why redis_setup_pubsub is rated Medium

An AI agent can call redis_setup_pubsub 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 redis_setup_pubsub 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 redis_setup_pubsub, this is the rule to start with:

redis_setup_pubsub Rate-limited

redis_setup_pubsub 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.
