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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "calls_list",
    "arguments": {}
  }
}
```

## Why calls_list is rated Low

This tool retrieves call records from HubSpot CRM with optional filters but does not create, modify, delete, or execute any operations. It has no side effects beyond retrieving existing data. Even if an AI agent misuses it by listing all calls, the blast radius is limited to information disclosure, which is low severity in a data retrieval context.

From the tool's own definition: "Tool name 'calls_list' and description 'List all calls with optional filtering' indicate data retrieval with no modification or deletion. The verb 'List' and qualifier 'optional filtering' are characteristic of read-only query operations."

## Use case

AI agents call calls_list to retrieve information from HubSpot MCP 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 HubSpot MCP:

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