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

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:

• Sign up for a Starling Developers account

• Link your Starling Bank account to your Starling Developer account

• Create the access token, selecting the scopes based on what you want the AI system to be able to access

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.
