## Facts

- Tool: `list_instances`
- 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_instances",
    "arguments": {}
  }
}
```

## Why list_instances is rated Low

This tool performs a read-only operation to list existing instances. It has no side effects, does not modify infrastructure, and poses minimal risk even if misused by an AI agent. The worst outcome would be exposure of instance metadata that is typically already visible to authorized users.

From the tool's own definition: "Tool name 'list_instances' and description 'Get a list of all Linode instances' indicate a query operation that retrieves data without modifying or deleting anything."

## Use case

AI agents call list_instances 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_instances": {}
  }
}
```

## 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`
