- 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

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

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

## Why list_nodebalancers is rated Low

This tool performs a read-only query to retrieve NodeBalancer resources. It has no side effects, does not execute code or commands, does not modify data, and does not delete or move resources. The blast radius of misuse is minimal—an AI agent could only view existing NodeBalancer configurations, which is a standard read operation on cloud infrastructure inventory.

From the tool's own definition: "Tool name 'list_nodebalancers' and description 'Get a list of all NodeBalancers' indicate a retrieval operation with no modification or execution of infrastructure."

## Use case

AI agents call list_nodebalancers 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_nodebalancers": {}
  }
}
```
