Inject live Marqeta data into Cursor code

Your agent can now call `get_balances` or `get_card` and paste the actual output into your codebase. No more guessing what the API structure looks like while you write your integration logic. It works during the edit process. When you ask your agent to build a new payment feature, it uses real data to shape the code, ensuring your implementation matches the actual platform behavior.

Automate card issuing logic

Write scripts that use `create_card_product` and `create_user` as if they were local functions. The agent understands the tool definitions, allowing it to scaffold complex onboarding flows in seconds. This keeps your code accurate. Because the agent interacts with the actual API, you avoid the common trap of writing stubs that break the moment you hit production.

Debug payment flows in the editor

Run `simulate_authorization` inside Cursor to verify your logic before you commit. You can see how your code responds to various transaction outcomes without leaving your file tree. It’s a tight loop. You write the code, call the simulation tool, and refine your logic based on the instant JSON feedback you receive.

Setup guide

Set up Marqeta MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Marqeta MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Marqeta transactions." If the MCP tools are loaded correctly, Cursor will call the Marqeta tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

  "mcpServers": {
    "marqeta-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
