WHAT IT DOES

What datePicker does on Genkit MCP

AI agents call datePicker as a supporting operation in Genkit MCP workflows.

RISK

Why datePicker is rated Low

The datePicker tool is a UI interaction component that allows a user to input a date. It does not read from a data store, write or modify persistent data, execute code, perform destructive actions, or involve financial transactions. It is purely a user-facing input mechanism, placing it in the 'Other' category. Severity is low as misuse has minimal blast radius — at worst, an incorrect date is submitted.

From the tool's definition 'user can use this UI tool to enter a date' — this is a UI input widget that captures a date value from the user, with no data retrieval, modification, execution, or financial action described

RECOMMENDED RULE

The rule that runs datePicker safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Genkit MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For datePicker, this is the rule to start with:

datePicker Rate-limited

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

View as policy code

policy.json

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

SET A RULE FOR THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Genkit MCP, apply this rule, and every datePicker call is checked against it from then on.
