Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

NPM package starling-bank-mcp
Claude Code 
claude mcp add starling-bank -e 'STARLING_BANK_ACCESS_TOKEN=<your starling_bank_access_token>' -e 'STARLING_BANK_PRIVATE_KEY_UID=<your starling_bank_private_key_uid>' -e 'STARLING_BANK_PRIVATE_KEY_PEM=<your starling_bank_private_key_pem>' -- npx -y starling-bank-mcp@1.2.1

starling-bank-mcp

MCP server for Starling Bank API integration, providing tools to interact with Starling Bank's developer API for account management and transactions.

https://github.com/user-attachments/assets/c2b23c22-bd23-487e-a4f5-c62e02280052

This is a 3rd party integration, and is not affiliated with Starling Bank.

[!WARNING] At time of writing, models make frequent mistakes and are vulnerable to prompt injections. As this MCP server gives the model some control of your bank account, mistakes could be costly. Use with caution and at your own risk.

Installation

Follow the instructions on install-mcp, which generates the right config for your MCP client (Claude Code, Claude Desktop, Cursor, Cline, VS Code, and more).

You'll need a Starling Bank personal access token. To create one:

Set it as STARLING_BANK_ACCESS_TOKEN (replacing the placeholder in the generated config). It'll probably begin something like eyJhbGciOiJQUzI1NiIsInppcCI6IkdaSVAifQ., and be moderately long.

If you want to be able to send payments, also see PAYMENT_SIGNING_SETUP.md.

Advanced: HTTP Transport

By default, the server uses stdio transport (for Claude Desktop, Cursor, etc.). You can also run it as an HTTP server:

STARLING_BANK_ACCESS_TOKEN=eyJhb... MCP_TRANSPORT=http PORT=3000 npx starling-bank-mcp

The MCP endpoint will be available at http://localhost:3000/mcp.

[!WARNING] The HTTP transport has no authentication. Other processes on your machine—including websites in your browser—could potentially access the endpoint and control your bank account. Only use HTTP transport behind a reverse proxy or in another secured setup.
