Perplexity

Full gateway control in Claude Desktop

Execute `auth_capture_transaction` or `auth_only_transaction` directly from your chat window. This lets you handle payment flows while keeping your context intact. Running `get_unsettled_transactions` keeps you updated on batch status. You see exactly what needs attention before the day ends.

Automate customer profile management

Use `create_customer_profile` to register new users in your database. It links billing info to your gateway records without manual data entry. Adding payment methods is just as simple with `add_payment_profile`. Your agent handles the details while you focus on the architecture.

Fast transaction lookups

Run `get_transaction_details` to pull specific records when a customer asks about a charge. You get the raw data instantly. Processing a `refund_transaction` takes seconds. Just provide the ID and amount, and the MCP Server handles the rest.
