Deploy Modulr tools in Cursor Agent mode

Give your code editor direct access to your banking infrastructure. The agent can now create beneficiaries and accounts while you write the surrounding logic. Use `modulr_create_beneficiary` to map external recipients in real-time. The agent injects the response directly into your codebase for immediate validation.

Execute payments from your Cursor workflow

Move money through your application code by triggering server tools. You don't have to leave your IDE or open a terminal to verify if a payment went through. Call `modulr_create_payment` to push funds. Because the tool is integrated into Cursor, you can see the response payload and debug your implementation logic side-by-side.

Sync ledger states using Cursor

Pull live transaction data to ensure your local database matches the banking reality. This keeps your development environment consistent with production ledger states. Run `modulr_get_accounts` to see current balances. This helps you verify that your code correctly interprets the liquidity data returned by the API.

Setup guide

Set up Modulr 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 Modulr 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 Modulr transactions." If the MCP tools are loaded correctly, Cursor will call the Modulr tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

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

Common questions about Modulr MCP in Cursor

Create a .cursor/mcp.json file in your project root. Define the server path there, and ensure Agent mode is toggled on to start using the tools.

Absolutely. You can write scripts in your editor that call these tools to simulate real-world payment flows and verify your logic against live API responses.

Vinkius manages the MCP Server in a zero-trust environment. The connection is authenticated via your endpoint token, and no keys are stored in your repo.

Yes. You can script the agent to loop through payment arrays, and it will execute each one while managing the necessary HMAC headers for you.

It accesses transaction logs, account balances, and beneficiary details. This sensitive financial data is transient and used only to populate your code context.
