WHAT IT DOES

What flag_message does on AirMCP

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

RISK

Why flag_message is rated Medium

Flagging or unflagging an email is a reversible modification to message metadata. It does not delete, execute code, or involve financial operations. The action can be undone by toggling the flag state again, making this a Write operation with low blast radius.

RECOMMENDED RULE

The rule that runs flag_message safely

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

flag_message Rate-limited

flag_message 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.

          "max": 30,

      ]
    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every flag_message call is checked against it from then on.

Can I rate-limit flag_message? +
