WHAT IT DOES

What dr_send_x_event does on 0nmcp

AI agents use dr_send_x_event to create or update resources in 0nmcp, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your 0nmcp environment.

RISK

Why dr_send_x_event is rated Medium

An AI agent can call dr_send_x_event faster than any human can review: one bad instruction and it creates or modifies resources in 0nmcp by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs dr_send_x_event safely

PolicyLayer is an MCP gateway: it sits between your AI agents and 0nmcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For dr_send_x_event, this is the rule to start with:

dr_send_x_event Rate-limited

dr_send_x_event 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.
