WHAT IT DOES

What trade_respond does on A2A-MCP-World

AI agents use trade_respond 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 trade_respond is rated Medium

This tool modifies the state of a pending trade by either accepting or declining it, which is a reversible write operation within the game world engine. While 'trade' might suggest financial implications, this is an in-world simulation mechanic (historical figures in a cafe game world), not actual financial transactions.

RECOMMENDED RULE

The rule that runs trade_respond 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 trade_respond, this is the rule to start with:

trade_respond Rate-limited

trade_respond 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.
