# stop_multiplayer_test

Stop every client process launched by start_multiplayer_test; exited clients are cleared while failed live kills remain tracked for retry. Optionally disconnect the host lobby. alsoStrays is an explicit recovery switch that kills every sbox.exe game client, including clients not launched by this harness; it never targets the sbox-dev editor process. Returns truthful stopped/remainingPids, per-process cleanup results, and disconnect status.

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

```json
{
  "jsonrpc": "2.0",

## Why stop_multiplayer_test is rated High

Terminates running game processes and network connections; effects depend on game state and cannot be partially undone.

From the tool's own definition: "Stop every client process, kills sbox.exe game clients, disconnect host lobby."

Risk signals: Bulk/mass operation — affects multiple targets

## Use case

AI agents invoke stop_multiplayer_test to trigger actions in Sbox. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Sbox:

```json

  "default": "deny",
  "tools": {
    "stop_multiplayer_test": {
      "limits": [
        {
