WHAT IT DOES

What resume_interaction does on A2a Cloud

AI agents use resume_interaction to create or update resources in A2a Cloud, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your A2a Cloud environment.

RISK

Why resume_interaction is rated Medium

An AI agent can call resume_interaction faster than any human can review: one bad instruction and it creates or modifies resources in A2a Cloud by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs resume_interaction safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A2a Cloud, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For resume_interaction, this is the rule to start with:

resume_interaction Rate-limited

resume_interaction 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.
