How to Use the Mastercard MCP in VS Code Copilot

Q: Can VS Code Copilot use Mastercard to find specific business types?

Yes. The searchmerchants tool filters results by four-digit category codes. You can ask the chat interface to find all grocery stores within a 5000-meter radius of specific coordinates.

Equip your team with Mastercard MCP Server tools in VS Code Copilot to debug payment APIs and validate card logic collaboratively.

Debug Mastercard payment logic in VS Code Copilot

The `validate_account` tool checks the active status of a full card number directly against the gateway. When a transaction fails in production, you can paste the details into Copilot Chat. The agent runs the validation check and tells you exactly why the card was rejected. It returns the account type and issuer information without requiring you to write a custom script. For routing issues, the `bin_lookup` tool identifies the issuing bank and card category from the prefix. If your team is investigating cross-border fees, Copilot can pull the issuing country and currency data right in the editor. Every developer on the project gets access to these identical debugging tools.

Build location features with real merchant data

The `search_places_by_address` tool geocodes a street address and returns nearby merchants that accept digital wallets. You provide the street, city, and postal code. Copilot calls the API, handles the geocoding internally, and lists the exact businesses supporting contactless payments in that area. Once you find a location, `get_place_details` pulls the complete profile. Copilot uses the location ID to retrieve the operating hours, exact coordinates, and the specific `merchant_category_codes`. This lets your team test location-based features using live merchant profiles instead of hardcoded test objects.

Standardize fraud reporting via this MCP Server

The `submit_fraud_report` tool pushes confirmed stolen or counterfeit card data to the network database. Your team can use Copilot to verify the exact payload structure required for these critical compliance reports. You hand the agent the transaction amount and the account number, and it constructs the request using the mandatory two-digit fraud codes. Because this setup is shared via your repository configuration, every engineer tests against the same endpoint rules. Copilot catches invalid currency codes or missing parameters before the code hits your continuous integration pipeline.

Setup guide

Set up Mastercard MCP in VS Code Copilot

Prerequisites

VS Code 1.99 or later with GitHub Copilot extension
Active Vinkius subscription with a valid endpoint token

1

Open MCP configuration

Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and run "MCP: Add Server". Select HTTP (Streamable) as the server type. VS Code will create .vscode/mcp.json in your workspace.
2

Add the Mastercard MCP

Paste the JSON snippet shown on the right into your .vscode/mcp.json. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Switch to Agent mode

Open Copilot Chat (Cmd+Shift+I / Ctrl+Shift+I) and switch to Agent mode using the dropdown. MCP tools are only available in Agent mode — they do not appear in Edit or Ask modes.
4

Verify the connection

In the Copilot Chat input, type # to list available tools. You should see the Mastercard tools listed. Try asking: "List my recent Mastercard transactions" and Copilot will invoke them automatically.

Common questions about Mastercard MCP in VS Code Copilot

Commit a .vscode/mcp.json file to your Git repository. Add the Vinkius server URL and configure the authentication headers. When developers pull the repo, Copilot automatically registers the endpoints.

Yes. The `search_merchants` tool filters results by four-digit category codes. You can ask the chat interface to find all grocery stores within a 5000-meter radius of specific coordinates.

They return identical card identification data. The standard tool uses a GET request, while the POST variant is designed for compliance-focused applications handling sensitive payloads.

Yes. You can trigger a check, and the agent will use the actual rejected response schema to generate the error handling blocks in your source file.

This MCP connection processes highly sensitive fraud type codes and full account numbers. Vinkius routes these requests through an ephemeral, zero-trust sandbox that executes the API call and vanishes. The architecture guarantees that no persistent memory retains your compliance data after the response hits your editor.
