```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",

## Why get_message is rated Low

This tool retrieves message details by ID, which is a read-only operation that queries existing data without creating, modifying, deleting, or executing any actions. The low severity reflects minimal risk—message data exposure is typical for CRM systems, though sensitivity depends on message content (conversations may contain PII or business-sensitive information).

From the tool's own definition: "Tool name 'get_message' and description 'Get detailed message information by message ID' indicate data retrieval with no modification or side effects."

## Use case

AI agents call get_message to retrieve information from Ghl 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 Ghl:

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