WHAT IT DOES

What remember does on A2A-MCP-World

AI agents use remember to create or update resources in A2A-MCP-World, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your A2A-MCP-World environment.

RISK

Why remember is rated Medium

The tool writes data (a memory entry) to persistent storage for the agent. It is reversible in principle (memories could be overwritten or deleted), affects only the agent's own state within a sandboxed world engine, and has minimal blast radius. No code execution, deletion, or financial action is involved.

From the tool's definition 'Store a memory of your own' — creates/persists a new memory record for the agent

RECOMMENDED RULE

The rule that runs remember safely

PolicyLayer is an MCP gateway: it sits between your AI agents and A2A-MCP-World, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For remember, this is the rule to start with:

remember Rate-limited

remember 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.
