# list_breakpoint_events

List HELD (paused) breakpoint exchanges — the READ side of the breakpoint-continue flow (public.breakpoint_events; a row with resumed_at NULL is a request/response the proxy is holding RIGHT NOW, waiting for breakpoint_continue — feed it the returned request_id). YOUR OWN devices' events by default (owner-scoped to the calling account — the same reach the dashboard /breakpoints page gives you), or EVERY device with all:true (devices:view operators only; re-verified server-side — for a non-operator all is rejected, never silently widened). Each row is a SLIM projection: id, request_id, device_uuid + device_name (the human name, resolved via the devices join — never a bare uuid), workspace_id, kind (request|response), paused_at, resumed_at, outcome (continued|dropped|edited|timeout|null), held. Currently-held rows only by default; pass include_resumed:true for the recent resolved history too. Never returns the raw HTTP bodies (slim payloads). Read-only, no confirm. Returns { ok, scope: own|fleet, count, events }.

## Facts

- Tool: `list_breakpoint_events`
- Server: Busymate DevTools (`https://mcp.busymate.dev`) — https://policylayer.com/tools/dev-busymate-busymate-devtools.md
- Homepage: https://github.com/serebano/busymate-devtools
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 3
- Recommended policy verdict: Allowed

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `all` | boolean | no | devices:view operators only — held breakpoints for EVERY device instead of just YOUR OWN. |
| `limit` | number | no | Max rows (default 100, cap 500). |
| `include_resumed` | boolean | no | Include already-resumed rows (the recent history) — default false lists only currently-held pauses. |

Parameters from the server's own tool schema.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "list_breakpoint_events",
    "arguments": {}
  }
}
```

## Why list_breakpoint_events is rated Low

Even though list_breakpoint_events 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.

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Busymate DevTools:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_breakpoint_events": {}
  }
}
```
