The x402 paywall settles Nevermined plan tokens, so generic x402 clients need its SDK or API to pay.\n\n**PayPal MCP server.** The hosted server uses OAuth with PKCE and dynamic client registration, and the local package defaults to the sandbox. No tool carries a read-only or destructive annotation, no confirmation step for refunds or captures was found, and the documented `/http` streamable HTTP path returned 404 on 8 October 2026 while `/mcp` answered.\n\n## Before you call either\n\n### Nevermined API + MCP\n\n1. Call `quote_service` before `pay_service`; quotes cost nothing\n2. Ask the person to open the `setup_delegation` URL once; you can't mint the first key or budget yourself\n3. Branch on the error `code` and retry only when `retryable` is true\n4. Create a small, short delegation per task; cards stop at $10.00 across delegations unless the owner raises it\n5. Use `sandbox:` keys and mcp.sandbox.nevermined.app until the flow works\n\n### PayPal MCP server\n\n1. Connect a remote client to `https://mcp.paypal.com/mcp` or `/sse`. The documented `/http` path returned 404 on 8 October 2026\n2. Set `PAYPAL_ENVIRONMENT=PRODUCTION` for live calls. Any other value, including the registry's `LIVE`, runs against the sandbox\n3. Refresh `PAYPAL_ACCESS_TOKEN` before it expires. The README gives `expires_in` 32400 seconds, and the local server takes no client ID or secret\n4. Pass `--tools=` with only the keys the task needs, such as `invoices.list,orders.get`. `--tools=all` loads 28 keys including refunds and captures\n5. Ask the user before `create_refund`, `pay_order`, `cancel_subscription` or `accept_dispute_claim`. The server applies them without a confirmation step\n\n## Questions\n\n### Which is better for AI agents, Nevermined API + MCP or PayPal MCP server?\n\nNevermined API + MCP scores 70.8 (BB) on agent readiness against PayPal MCP server's 56.3 (C), and leads in 6 of 7 scored categories.
