Why hwp_ping_pong needs a policy

The description is empty and uninformative, making it impossible to definitively classify the tool. The name 'ping_pong' commonly refers to a health check or connectivity test (a server sends a ping, client responds with pong), which would be a read/diagnostic operation with minimal blast radius. Given the context of other HWP document manipulation tools, this is likely a simple connectivity test.

From the tool's definition Tool name is 'hwp_ping_pong' with an empty description. The name suggests a connectivity/health-check operation (ping-pong pattern).

POLICY

How to control hwp_ping_pong

PolicyLayer is an MCP gateway — it sits between your AI agents and HWP MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for hwp_ping_pong:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "hwp_ping_pong": {
      "limits": [
        {
          "counter": "hwp_ping_pong_rate",
          "window": "minute",
          "max": 60,
          "scope": "grant"
        }
      ]
    }
  }
}

hwp_ping_pong gets a rate cap, and everything else on the server is denied unless you say otherwise.

Create a free account and register HWP MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
