THE RISK

Low Risk

Why greet needs a policy

This tool only produces a greeting message to the user. It has no side effects, does not read sensitive data, modify state, execute code, or involve any financial operations. It is a benign, informational output tool that fits none of the primary risk categories.

From the tool's definition "Greet the use with a message" — purely generates a greeting message with no data retrieval, modification, execution, or financial action

POLICY

How to control greet

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

policy.json

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

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

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