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

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

## Why update_user is rated Medium

The tool modifies user data, which falls under the Write category (creates or modifies data reversibly). Severity is high because unauthorized user updates could modify credentials, permissions, email addresses, or other sensitive profile information, potentially compromising account security or escalating privileges.

From the tool's own definition: "Tool name 'update_user' and description 'Update one user by ID' indicate modification of user data. The action is reversible (data can be updated again) rather than destructive. This is a write operation that modifies existing user records."

## Use case

AI agents use update_user to create or update resources in Mealie MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mealie MCP Server environment.

## Recommended policy (PolicyLayer)
