THE RISK

Low Risk

Why ping needs a policy

Ping is a read-only operation that tests connectivity and receives a response. It has no destructive, financial, or code-execution implications, and produces no side effects on the QGIS system or data. Severity is low because even if misused, a ping cannot harm data or operations.

From the tool's definition Tool name is 'ping' with description 'Simple ping command to check server connectivity' — a diagnostic probe that retrieves server status without modification or side effects.

POLICY

How to control ping

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

policy.json

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

ping is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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

FAQ

Questions about ping

What does the ping tool do? +

Simple ping command to check server connectivity. It is categorised as a Read tool in the QGISMCP MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on ping? +

Register the QGIS MCP server in PolicyLayer and add a rule for ping: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches QGISMCP. Nothing to install.

What risk level is ping? +

ping is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit ping? +

Yes. Add a rate_limit block to the ping rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block ping completely? +

Set action: deny in the PolicyLayer policy for ping. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides ping? +

ping is provided by the QGIS MCP server (kicker315/deepseek_qgis_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every QGISMCP tool call.

Start from QGISMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
