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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "check_llc_name",
    "arguments": {
      "name": "<name>",
      "state": "<state>"
    }
  }
}
```

## Why check_llc_name is rated Low

Even though check_llc_name only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

## Use case

AI agents call check_llc_name to retrieve information from FilingDesk Data 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 FilingDesk Data:

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