MIT · runs locally with your own credentials

Quickstart

Install, set the credentials, make the first call.

Pick your client. The server runs locally over stdio, with your own credentials.

Tools

What your agent can call.

Authorize a transaction (reserve funds without capturing) via Braintree GraphQL authorizePaymentMethod. Pass a paymentMethodId obtained from client-side tokenization (Drop-in / Hosted Fields / SDK nonce). Capture later with capture_transaction.

Authorize and capture a transaction atomically via Braintree GraphQL chargePaymentMethod. Use for one-step sales. For auth-now-capture-later split, use authorize_transaction + capture_transaction.

Capture a previously authorized transaction via captureTransaction. Amount defaults to full authorized amount when omitted (partial captures allowed up to the authorized total).

Refund a settled transaction via refundTransaction. Amount defaults to the full settled amount when omitted. For partial refunds, pass a smaller amount.

Void an unsettled transaction (reverse the authorization) via reverseTransaction. Use when funds are authorized but not yet captured — for captured/settled transactions use refund_transaction instead.

Permanently store a tokenized payment method in the Braintree vault via vaultPaymentMethod. The input paymentMethodId must be a single-use nonce; the mutation returns a permanent vaulted payment method id that can be reused for future charges.

Delete a vaulted payment method via deletePaymentMethodFromVault. Irreversible — the token cannot be used for future charges after deletion.

Create a Braintree customer via createCustomer. Customers group multiple vaulted payment methods and transactions under one identity.

Update an existing Braintree customer via updateCustomer. Only fields present in the request are updated.

Fetch a transaction by id via the GraphQL search.transactions query. Returns id, status, amount, orderId, createdAt, and the associated payment method.

Fetch a customer by id via the GraphQL node(id:) query. Returns customer scalars (id, firstName, lastName, email, company, phone).

Submit a previously authorized transaction for settlement via submitTransactionForSettlement. Unlike capture_transaction (captureTransaction), this marks the transaction for the next settlement batch and supports optional order id / descriptor overrides.
