Allow AI systems to view and control your Starling Bank account via MCP.

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.
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.
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.
