Markdown https://www.anchorterminal.com/tools/stripe-mcp.md · JSON https://www.anchorterminal.com/api/v1/tools/stripe-mcp.json ## Which one, for what ### PayPal MCP server (C) Good for: A merchant already on PayPal who wants an assistant to draft and send invoices, look up orders and transactions, and manage subscriptions and disputes. Watch for: The quickstart gives `/http` for streamable HTTP. On 8 October 2026 it returned 404 on both hosts, and `/mcp` returned the OAuth challenge ### Stripe API + MCP (A) Good for: Sellers already on Stripe who want to charge agents per call over MPP or x402 with fiat settlement, refunds and reporting, and for agents doing account work on Stripe with human approval for risky writes. nevermined suits sellers who want plans, credits and buyer-side caps; tempo is the chain MPP stablecoin payments settle on.

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. **Stripe API + MCP.** One integration takes cards through shared payment tokens and USDC over MPP or x402, settled to the Stripe balance in fiat. Card payments from agents have a 0.50 USD minimum, so per-call micropayments must use stablecoins. ## Before you call either ### 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 ### Stripe API + MCP 1. Switch to an Agent-tagged restricted key or OAuth before 31 October 2026; other keys get a 401 2. Call `stripe_api_search` and `stripe_api_details` before `stripe_api_write` to get the method and parameters right 3. When a write needs approval, give the person the URL and retry only after they approve; approvals expire after 24 hours 4. Send an `Idempotency-Key` on every create so a retry can't charge twice 5. On 429, read `Stripe-Rate-Limited-Reason` and back off with jitter; a 429 without it is a lock timeout ## Questions ### Which is better for AI agents, PayPal MCP server or Stripe API + MCP?
