## Facts

- Tool: `list_vlans`
- 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: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why list_vlans is rated Low

This tool retrieves information about Virtual Local Area Networks (VLANs) in the Linode environment. Listing operations are read-only with no side effects, no code execution, and no data modification. The blast radius of misuse is minimal—an attacker could enumerate network topology but cannot modify, delete, or execute actions. This is a standard Read category tool.

From the tool's own definition: "Tool name is 'list_vlans' and description states 'List all VLANs' - a query operation that retrieves network configuration data without modification or execution."

## Use case

AI agents call list_vlans to retrieve information from Linode MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_vlans": {}
  }
}
```

## 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`
