Alternative Payments MCP Server
A Model Context Protocol (MCP) server that gives AI assistants read + safe-write access to Alternative Payments — customers, invoices, payment requests, transactions, payouts, and webhooks.
Maintained by Wyre Technology.
Capabilities
This server deliberately does not move money. It exposes reads and safe writes
(creating customers, invoices, and hosted payment links). It does not implement
direct payment creation (POST /payments), which would charge a card or bank account.
The three destructive tools — ap_archive_customer, ap_archive_invoice,
ap_delete_webhook — require interactive confirmation before they run.
| Domain | Tools |
|---|---|
| customers | ap_list_customers, ap_get_customer, ap_list_customer_users, ap_create_customer, ap_add_customer_user, ap_archive_customer ⚠ |
| invoicing | ap_list_invoices, ap_get_invoice, ap_get_invoice_payment_link, ap_get_invoice_pdf_link, ap_create_invoice, ap_create_payment_request, ap_get_payment_request, ap_archive_invoice ⚠ |
| payments | ap_list_transactions, ap_get_transaction, ap_list_payouts, ap_get_payout, ap_list_payout_transactions |
| webhooks | ap_list_webhooks, ap_list_webhook_events, ap_create_webhook, ap_retry_webhooks, ap_delete_webhook ⚠ |
Plus discovery tools ap_navigate and ap_status.
Authentication
Alternative Payments uses OAuth 2.0 client-credentials. Generate an API key
(client_id / client_secret) in the Partner Dashboard. Set:
ALTERNATIVE_PAYMENTS_CLIENT_IDALTERNATIVE_PAYMENTS_CLIENT_SECRETALTERNATIVE_PAYMENTS_ENVIRONMENT(productionordemo, defaultproduction)
The server exchanges these for a bearer token automatically and refreshes it before expiry.
Quick start
Claude Code (CLI):
claude mcp add alternative-payments \
-e ALTERNATIVE_PAYMENTS_CLIENT_ID=your-client-id \
-e ALTERNATIVE_PAYMENTS_CLIENT_SECRET=your-client-secret \
-- npx -y github:wyre-technology/alternative-payments-mcp
Docker (HTTP transport, gateway mode):
docker run --rm -p 8080:8080 \
-e AUTH_MODE=env \
-e MCP_TRANSPORT=http \
-e ALTERNATIVE_PAYMENTS_CLIENT_ID=... \
-e ALTERNATIVE_PAYMENTS_CLIENT_SECRET=... \
ghcr.io/wyre-technology/alternative-payments-mcp:latest
Transports
- stdio (default):
node dist/index.js - HTTP (
MCP_TRANSPORT=http): streamable HTTP onMCP_HTTP_PORT(default 8080), with/mcpand/healthendpoints. Each request gets a fresh stateless server, which is required for the WYRE MCP Gateway.
