MCP Rinne runs on your own machine — the client starts it, so there is no endpoint to ping. 16 installs a week from npm. Last commit 29 Aug 2026.
Brazilian card acquiring API — merchants, cards-on-file, 3DS, PIX, banking, pricing.
Today is the operative word: we check MCP Rinne every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
RINNE_API_KEY (API key sent as x-api-key header on every request. Organization-level keys see all merchants; merchant-level keys are scoped to one merchant.), RINNE_SANDBOX (Defaults to sandbox (https://api-sandbox.rinne.com.br/core). Set to "false" for production (https://api.rinne.com.br/core).), RINNE_EMAIL (Login identifier for the access-management tools (API Keys, Roles, Permissions, org Users, Zipcode lookup), which reject x-api-key by design and require a JWT session.), RINNE_PASSWORD (Login password paired with RINNE_EMAIL.), RINNE_COMPANY_ID (Company to select after JWT login, for accounts with access to multiple companies.).
