  "jsonrpc": "2.0",

## Why getUsersPublicKeys is rated Low

This tool queries and retrieves existing public encryption keys—a read-only operation. Public keys are intentionally shareable data, and retrieval does not modify state or trigger external operations. The action is informational only, consistent with the Read category.

From the tool's own definition: "Tool name 'getUsersPublicKeys' and description 'Retrieve public encryption keys for multiple users' indicate a retrieval operation with no data modification or side effects."

## Use case

AI agents call getUsersPublicKeys to retrieve information from Xdevplatform/xmcp 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 Xdevplatform/xmcp:

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