Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This server provides 10 capabilities that interface natively with Claude, ChatGPT, Cursor, and any MCP client. No middleware. No custom integration required.
Reconciling payments after hours is a nightmare of tabs and exports.
Right now, when money moves in e-commerce, someone has to log into the payment gateway's portal. They have to find the specific transaction ID, check if it was authorized or settled, then maybe jump over to a spreadsheet to cross-reference amounts and dates. If there's an issue, they manually click through voiding buttons or submitting refund requests.
With this MCP, that whole process vanishes. You just tell your agent what needs fixing—say, 'Void the batch from yesterday.' It executes the command directly against the gateway API. The result is immediate confirmation: done.
The Authorize.net MCP gives you control over payments and refunds.
You don't have to manually manage customer credit cards or build complex profile storage solutions yourself. You simply let the agent handle the secure creation of profiles using `create_customer_profile` and store card data in a safe, isolated way.
The difference is that instead of relying on a slow-loading web page with confusing menus, you use plain language to drive powerful financial actions across your entire stack.
What you can do with this MCP connector
Running e-commerce payments shouldn't require three different dashboards and a manual spreadsheet reconciliation every night. This MCP connects your payment gateway to your AI agent so you can handle the full financial flow using natural conversation. Forget logging into the merchant interface just to void a batch or check why a card declined; you tell your agent, and it handles the API calls for you.
It manages everything from creating secure customer profiles to running an 'Auth & Capture' transaction in one go. You even get visibility on unsettled transactions waiting for batch closure. Vinkius hosts this MCP so that any compatible AI client—whether Claude or Cursor—gets access to all these tools, meaning your payment logic is always accessible wherever you work.

How Authorize.net MCP Works
- 1 Subscribe to this MCP and provide your Authorize.net Login ID, Transaction Key, and environment mapping.
- 2 Your AI agent connects directly using the credentials, giving it access to the gateway's API functions.
- 3 You give a direct command—for instance, 'Void transaction 91230.' The agent runs the correct function and reports success or failure.
The bottom line is you stop dealing with clunky web portals and start controlling payment logic via pure dialogue.
Who Is Authorize.net MCP For?
This MCP is for anyone whose job involves money movement, especially e-commerce operations. If you're tired of switching between a dashboard, a spreadsheet, and an API console to complete simple tasks like issuing refunds or checking batch statuses, this is for you.
You execute post-return refunds dynamically, ensuring the money gets back to the customer immediately without manual API calls.
You systematically track unresolved unsettled holds prior to batch processing or pull detailed reports on specific transaction IDs for auditing.
You verify exactly why a card was declined—checking the AVS or CVV logic flaws—and relay that information instantly to support staff.
What Changes When You Connect
- You manage funds by running an 'Auth & Capture' transaction, confirming the sale and moving money instantly without extra steps.
- Refunds are simple; you can issue a refund using
refund_transactionjust by telling your agent the original ID and amount. No form filling required. - Need to check if a card declined? You run
get_transaction_detailsto see the exact decline reason—AVS or CVV failure—instantly for troubleshooting. - Instead of manually deleting records, you can use
void_transactionon anything unsettled, stripping it clean before batch processing starts. - You build secure customer accounts with
create_customer_profile, making it easier to process future sales without collecting raw card data. - The agent handles the audit trail. By calling
get_unsettled_transactions, you see exactly what money is floating and needs attention before the nightly close.
Real-World Use Cases
Processing a Post-Return Refund
A customer returns an item. Instead of navigating to the merchant portal, you tell your agent: 'Refund transaction XYZ for $50.' The agent immediately executes refund_transaction using the correct ID and amount.
Debugging a Declined Payment
A sale fails. You ask the agent to check the details of that payment attempt. It runs get_transaction_details, telling you, 'It failed because the AVS zip code didn't match.' This saves troubleshooting time.
Cleaning Up Batch Holds
The day ends and there are several transactions that should never have happened. You tell the agent to list unsettled items, run get_unsettled_transactions, and then execute void_transaction on all flagged IDs.
Completing a Multi-Step Sale
You authorize $50 for shipping, but the physical goods ship later. You tell your agent to run auth_only_transaction. Later, when items ship, you instruct it to use prior_auth_capture.
The Tradeoffs
Trying to check status manually
You spend 15 minutes clicking through the payment gateway's web interface and copying a transaction ID just to see if it settled.
→
Just tell your agent: 'What is the status of transaction ABC?' It runs get_transaction_details immediately, giving you the answer without leaving your chat window.
Missing required payment info
Attempting to refund a transaction but only providing the ID and amount. The system fails because it needs the original card data.
→
When using refund_transaction, you must provide three things: the original transaction ID, the full refund amount, and either the masked or raw PAN and expiration.
Confusing Auth and Capture
Assuming a payment hold (Auth) automatically becomes money in the bank. It doesn't.
→
Remember: auth_only_transaction just holds the funds temporarily. You must explicitly tell it to run prior_auth_capture later to finalize the money movement.
When It Fits, When It Doesn't
Use this MCP if your workflow involves multiple, sequential financial steps: creating a customer record, authorizing funds, capturing those funds, or managing post-sale actions like refunds and voids. You need control over the payment state machine. Don't use it just because you need to list transactions; for simple data lookup without action, a dedicated reporting tool might be cleaner. If your process is 90% 'read status' and only 10% 'write money,' this MCP is overkill. Use it when you are actively doing the work—when you have to run auth_capture_transaction or issue a refund.
Common Questions About Authorize.net MCP
How do I get detailed information using the get_transaction_details tool? +
You provide a specific transaction ID. The agent pulls deep records, showing you not just the status but also if the AVS and CVV checks passed when the payment went through.
Is there a way to refund a card without having the raw PAN? +
Yes, as long as you have the original transaction ID, the correct refund amount, and either the masked or raw PAN and expiration date, the refund_transaction tool handles it.
What is the difference between auth_only_transaction and auth_capture_transaction? +
The 'Auth Only' function places a temporary hold on funds. You must later run prior_auth_capture to finalize that transaction, making it permanent money movement.
Can I see all the pending batches with get_unsettled_transactions? +
Absolutely. Running this tool lists every single transaction currently awaiting batch closure so you know exactly what needs attention before end-of-day processing.
What information does `get_transaction_details` provide if a payment was declined due to AVS or CVV mismatch? +
It provides specific failure codes and reason mapping. The tool retrieves details beyond just the status, allowing you to see exactly why a card failed—for instance, whether an Address Verification System (AVS) check or a Card Verification Value (CVV) mismatch was the root cause.
How does using `add_payment_profile` keep my sensitive payment data secure? +
The system manages card details through isolated Customer Information Manager (CIM) profiles. When you use add_payment_profile, the MCP securely links the card information without exposing raw Primary Account Numbers (PANs) to unencrypted processes.
What credentials do I need before I can run any payment function, like `auth_capture_transaction`? +
You must provide your Authorize.net Login ID, Transaction Key, and the correct environment mapping. These are essential setup details that allow your AI client to authenticate directly with the gateway's API.
If an order is canceled before shipping, how do I cancel a temporary authorization hold using `void_transaction`? +
You use void_transaction to immediately nullify any pending holds. This reverses the funds that were temporarily captured by an 'Auth Only' process, ensuring those reserved limits are released quickly.
