MCP Rinne runs on your own machine — the client starts it, so there is no endpoint to ping. 34 installs a week from npm. Last commit 27 Sep 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.

Put your own value in place of
<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).
The author’s registry entry marks it as required.
Optional settings from the registry entry, left out of the block above:
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).
