  • Mercado Pago Claude Marketplace v4.2: offline mode and new features
  • Added

    • Offline mode: generate complete integration code without authentication, using bundled plugin files with official Mercado Pago documentation.
    • Automatic product and country detection: identifies product and country from natural language input (e.g., "integrate Checkout Pro for Brazil").
    • "/mp-test-cards [country]" command: retrieve test cards by country without login (BR, AR, MX, etc.).
    • "create_application" tool: create new applications from the plugin wizard (requires login).
    • Windows support: compatibility with Windows environments.
    • Multilingual responses: responds in Spanish, Portuguese, or English based on the language of the query.

    Changed

    Mercado Pago Plugin

  • Mercado Pago CLI v1.0.5: Fixes and command removals
  • Fixed

    • "capture" parameter: now sent only when the "--capture" flag is passed. It was previously included in all "mpcli payments create" requests, affecting methods that don't support it and overriding "--data" values. Review your calls if you relied on it being sent automatically.
    • Financial reports: fixed the endpoints for "mpcli reports releases list" and "settlements list", which returned errors on accounts with existing reports.

    Removed

    • "listen", "trigger", "events", and "logs" commands: removed as they are not available for general use.

    Fix

    Mercado Pago CLI

    April of 2026

  • Fix in Update card endpoint documentation in the Saved Cards API
  • We corrected the documentation for the Update card endpoint in the Saved Cards API to reflect the fields the request body actually accepts when updating a customer's card. The token field was removed, as the API does not accept it on this endpoint. The valid fields for the update are expiration_month, expiration_year, and cardholder (which includes name and identification).
