# app.launch

Launch an executable on the remote Windows rig (name on PATH or absolute path), optional args. Side effects: starts a process; Glasswarp tracks it and closes it on session.end. Use for notepad.exe, mspaint.exe, chrome with URL args, etc. Wait/re-observe after launch before clicking — do not assume the window is focused immediately.

## Facts

- Tool: `app.launch`
- Server: Glasswarp (`https://mcp.glasswarp.com/mcp`) — https://policylayer.com/tools/com-glasswarp-mcp-server.md
- Homepage: https://github.com/glasswarp/mcp-server
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server auth posture: open
- Server rate-limited: no
- Parameters: 3 (2 required)
- Recommended policy verdict: Rate-limited

## Parameters

| Parameter | Type | Required | Description |
| --- | --- | --- | --- |
| `args` | array | no | Process args, e.g. ["--new-window", "https://example.com"] |
| `session_id` | string | yes | Active session id |
| `path_or_name` | string | yes | Executable name (e.g. notepad.exe) or absolute path |

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": "app.launch",
    "arguments": {
      "session_id": "<session_id>",
      "path_or_name": "<path_or_name>"
    }
  }
}
```

## Why app.launch is rated High

app.launch triggers external process execution on a remote Windows machine with effects determined by the executable and arguments provided. This is a classic Execute pattern — the tool itself runs code/operations whose consequences depend on what is launched.

From the tool's own definition: "Tool description explicitly states 'Launch an executable on the remote Windows rig' and 'starts a process', clearly indicating code/process execution capability. The tool accepts arbitrary executables by 'name on PATH or absolute path' with optional arguments."

## Use case

AI agents invoke app.launch to trigger actions in Glasswarp. 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 Glasswarp:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "app.launch": {
      "limits": [
        {
          "counter": "app.launch_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
