Call `quote_service` before `pay_service`; quotes cost nothing 2. Ask the person to open the `setup_delegation` URL once; you can't mint the first key or budget yourself 3. Branch on the error `code` and retry only when `retryable` is true 4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it 5. Use `sandbox:` keys and mcp.sandbox.nevermined.app until the flow works ### PayPal MCP server 1. Connect a remote client to `https://mcp.paypal.com/mcp` or `/sse`. The documented `/http` path returned 404 on 8 October 2026 2. Set `PAYPAL_ENVIRONMENT=PRODUCTION` for live calls. Any other value, including the registry's `LIVE`, runs against the sandbox 3. Refresh `PAYPAL_ACCESS_TOKEN` before it expires. The README gives `expires_in` 32400 seconds, and the local server takes no client ID or secret 4. Pass `--tools=` with only the keys the task needs, such as `invoices.list,orders.get`. `--tools=all` loads 28 keys including refunds and captures 5. Ask the user before `create_refund`, `pay_order`, `cancel_subscription` or `accept_dispute_claim`. The server applies them without a confirmation step ## Questions ### Which is better for AI agents, Nevermined API + MCP or PayPal MCP server?
