Why redis-ping needs a policy

This tool executes an external operation (sends a PING command to a Redis instance) to test connectivity. While the PING command itself is read-only and harmless, it actively triggers an external network operation rather than just querying local data. Severity is low because PING has no side effects on data — it only tests whether the Redis server is reachable.

POLICY

How to control redis-ping

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "redis-ping": {
      "limits": [
        {
          "counter": "redis-ping_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

redis-ping stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Make — 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 redis-ping

What does the redis-ping tool do? +

Tests Redis connectivity by sending a PING command. It is categorised as a Execute tool in the Make MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on redis-ping? +

Register the Make MCP server in PolicyLayer and add a rule for redis-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 Make. Nothing to install.

What risk level is redis-ping? +

redis-ping is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit redis-ping? +

Yes. Add a rate_limit block to the redis-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 redis-ping completely? +

Set action: deny in the PolicyLayer policy for redis-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 redis-ping? +

redis-ping is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Make tool call.

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