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

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

## Why get_custom_values is rated Low

This tool retrieves and queries custom field values without side effects. It matches the Read category definition: 'retrieves or queries data; no side effects (search, list, get, fetch).' The verb 'list' and the passive data retrieval nature indicate no data modification or destructive potential. Low severity because exposure would only allow an agent to view existing custom values within the GoHighLevel CRM.

From the tool's own definition: "Tool description explicitly states 'List all custom values for a location' - a retrieval operation with no modification, deletion, or execution capability."

## Use case

AI agents call get_custom_values to retrieve information from GoHighLevel 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 GoHighLevel MCP Server:

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