Why uber_request_ride needs a policy

Requesting an Uber ride creates a real financial transaction: the user is charged for the ride. This falls squarely in the Financial category as it commits financial obligations. The blast radius is critical because an AI agent could book rides without explicit user confirmation, leading to unwanted charges and potential fraud.

From the tool's definition 'Request an Uber ride' — directly initiates a paid ride booking, committing a financial obligation on the user's account

POLICY

How to control uber_request_ride

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "uber_request_ride": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to uber_request_ride is blocked until a human approves it. The rest of the server keeps working.
