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

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

## Why mikrotik_update_filter_rule is rated Medium

The tool modifies firewall rules, which is a critical network security function, but the operation is reversible (rules can be updated again or reverted). This qualifies as Write rather than Execute or Destructive. However, the blast radius is high because misconfigured firewall rules could disrupt network connectivity, expose network segments, or enable unauthorized access.

From the tool's own definition: "Tool name contains 'update' and description states 'Updates an existing firewall filter rule on MikroTik device' — this modifies network security configuration reversibly."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches MikroTik Cursor MCP:
