## Facts

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

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

## Why ping is rated Low

A ping operation is a standard connectivity test that merely verifies service availability. It produces no observable state changes, retrieves no user data, and has no blast radius if misused—an agent could only spam ping requests, causing minimal harm. This is a benign Read category operation, classified as low severity.

From the tool's own definition: "Tool name 'ping' and description 'Check MCP and FeatureJet API reachability' indicate a diagnostic health check with no data retrieval, modification, or side effects."

## Use case

AI agents call ping to retrieve information from FeatureJet 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 FeatureJet:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
