WHAT IT DOES

What collab_session_heartbeat does on Agenttool

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

RISK

Why collab_session_heartbeat is rated Low

Even though collab_session_heartbeat only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs collab_session_heartbeat safely

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

collab_session_heartbeat Allowed

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

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

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

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