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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why ensure_passenger_deps is rated High

This tool runs package manager commands (npm install, pip install) on the server, which constitutes executing external processes. This can install arbitrary code packages, potentially introducing malicious dependencies or consuming server resources. The blast radius is high as it could affect production application dependencies.

From the tool's own definition: "Install/update dependencies for a registered application (npm install, pip install, etc.)"

## Use case

AI agents invoke ensure_passenger_deps to trigger actions in cPanel MCP Server. 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.
