Perplexity

Instant Pix generation in Claude Desktop chat

Generate instant Pix payments during chat sessions using `create_pix_payment`. Claude Desktop runs this MCP Server locally via stdio, spitting out the raw QR code payload right into your conversation. Paste that payload into your frontend or render it directly. No need to jump back and forth between your terminal and the Mercado Pago dashboard to verify if the payment intent went through.

Manage customer records via Claude Web

Connect this MCP Server to claude.ai via custom connectors to register new buyers. Your agent calls `create_customer` and `get_customer` to manage profiles using simple text prompts. This setup lets non-technical team members look up Brazilian tax IDs using `get_identification_types` without writing a single line of code. It acts as a direct bridge to your payment gateway.

Issue refunds directly from your desktop

Handle disputed charges by telling Claude Desktop to execute `refund_payment`. The local subprocess triggers the API immediately, processing either partial or full refunds based on your chat instructions. You can verify the refund status right after by calling `get_payment` in the same thread. It keeps your support workflow entirely inside your chat client without API token leaks.
