- Server: Linode MCP Server (`takashito/linode-mcp-server`) — https://policylayer.com/tools/takashito-linode-mcp-server.md
- Homepage: https://github.com/takashito/linode-mcp-server
- Risk category: Destructive (Critical risk)
- Registry record: grade F, identity unverified

- Parameters: 0
- Recommended policy verdict: Hidden

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

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

## Why revoke_authorized_app is rated Critical

Revoking OAuth access permanently removes an application's ability to authenticate and act on behalf of the user. This is effectively irreversible (the app must go through the authorization flow again), and misuse by an AI agent could disrupt integrations or services depending on that OAuth app's access.

From the tool's own definition: "'Revoke access for an authorized OAuth app' — revoking authorization is an irreversible action that removes an app's access token/credentials, which cannot be undone without re-authorization by the user."

## Use case

AI agents call revoke_authorized_app to permanently remove resources in Linode MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Linode MCP Server:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "revoke_authorized_app"
  ]
}
```
