rc_gate · RC Engine MCP: Risk & Policy

WHAT IT DOES

What rc_gate does on RC Engine

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

WHY IT NEEDS A POLICY

Why rc_gate needs a policy

The tool appears to accept and process user submissions through a gate/approval mechanism, which constitutes a Write operation (creates records, advances workflow state). The severity is medium given the context of a product development pipeline where submissions affect project progression but do not destroy data or execute arbitrary code. Confidence is reduced due to the truncated and uninformative description.

From the tool's definition Tool name 'rc_gate' with description 'Submit user' suggests a submission/gating mechanism that creates or modifies records in a product development pipeline. The incomplete description limits confidence.

Verdict

rc_gate Rate-limited

rc_gate 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.
