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

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

## Why get_top_gaps is rated Low

Even though get_top_gaps 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 get_top_gaps to retrieve information from Ddmarketer 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 Ddmarketer:

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