WHAT IT DOES

What list_participants does on AirMCP

AI agents call list_participants to retrieve information from AirMCP without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_participants is rated Low

This tool queries and returns information about chat participants without creating, modifying, deleting, or executing any operations. It is a pure read operation that retrieves existing data from a chat/messaging context. The blast radius is minimal—an agent listing chat participants causes no destructive, financial, or state-altering harm.

From the tool's definition Tool name 'list_participants' and description 'List all participants in a specific chat' indicate a retrieval operation with no side effects.

RECOMMENDED RULE

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

list_participants Allowed

list_participants is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_participants": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

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