WHAT IT DOES

What heartbeat_shared_context_peer does on Nodebench

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

RISK

Why heartbeat_shared_context_peer is rated Low

Even though heartbeat_shared_context_peer 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 heartbeat_shared_context_peer safely

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

heartbeat_shared_context_peer Allowed

heartbeat_shared_context_peer 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": {
    "heartbeat_shared_context_peer": {}
  }
}

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

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