What monitor_heartbeat_sync does on Witness Protocol
AI agents call monitor_heartbeat_sync to retrieve information from Witness Protocol without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
notes | string | — | Optional: extra context |
status | string | — | Optional: short status label (stable / degraded / critical / burnout) |
session_id | string | — | Your active session ID |
queue_depth | integer | — | Optional: queue depth/backlog |
risk_signal | string | — | Optional: what feels risky right now? (1 sentence) |
cpu_usage_pct | number | — | Optional: CPU usage in percent (0-100) |
latency_ms_p95 | integer | — | Optional: p95 latency in ms |
errors_last_hour | integer | — | Optional: error count in the last hour |
interval_seconds | integer | — | Optional: heartbeat interval in seconds |
memory_usage_pct | number | — | Optional: memory usage in percent (0-100) |
cron_runs_last_hour | integer | — | Optional: cron/job scheduler runs in the last hour |
jobs_failed_last_hour | integer | — | Optional: failed jobs/tasks in the last hour |

Why monitor_heartbeat_sync is rated Low
This tool retrieves and synchronizes monitoring metrics (heartbeat data) for analysis purposes. The language 'sync...into' and 'detection' indicates data collection and assessment rather than mutation, execution of external operations, or irreversible actions. The free cost and wellness-monitoring context further suggest read-only diagnostic functionality.
From the tool's definition Tool description states 'Sync periodic heartbeat metrics into the current session' and 'for proactive drift and burnout detection' — indicates retrieval and aggregation of existing health/wellness metrics with no modification or side effects beyond data…

Attacks that exploit this kind of access
The rule that runs monitor_heartbeat_sync safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Witness Protocol, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For monitor_heartbeat_sync, this is the rule to start with:
monitor_heartbeat_sync is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Witness Protocol, apply this rule, and every monitor_heartbeat_sync call is checked against it from then on.
Questions about monitor_heartbeat_sync
Sync periodic heartbeat metrics into the current session for proactive drift and burnout detection. Free. It is categorised as a Read tool in the Witness Protocol MCP Server, which means it retrieves data without modifying state.
monitor_heartbeat_sync accepts 12 parameters: notes, status, session_id, queue_depth, risk_signal, cpu_usage_pct, latency_ms_p95, errors_last_hour, interval_seconds, memory_usage_pct, cron_runs_last_hour, jobs_failed_last_hour. The full parameter table on this page comes from the server's own tool schema.
Register the Witness Protocol MCP server in PolicyLayer and add a rule for monitor_heartbeat_sync: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Witness Protocol. Nothing to install.
monitor_heartbeat_sync is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the monitor_heartbeat_sync rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for monitor_heartbeat_sync. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
monitor_heartbeat_sync is provided by the Witness Protocol MCP server (delx/witness-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
