Starling Bank — Claude Code MCP server: features and setup
Connect an AI agent to Starling Bank to work with account details and transactions. Payment sending needs an extra signing setup.
claude mcp add starling-bank-mcp -e STARLING_BANK_ACCESS_TOKEN=<STARLING_BANK_ACCESS_TOKEN> -e STARLING_BANK_PRIVATE_KEY_UID=<STARLING_BANK_PRIVATE_KEY_UID> -e STARLING_BANK_PRIVATE_KEY_PEM=<STARLING_BANK_PRIVATE_KEY_PEM> -- npx -y starling-bank-mcpWhat Starling Bank does
The server connects an agent to the Starling Bank API, giving it access to account management and transactions. A personal access token controls permissions through the scopes selected when you create it. Payments require a separate signing configuration.
In Claude Code, the server runs through npx over stdio. Setup also passes the private key UID and PEM values. The model can affect your bank account, and errors or prompt injection could be costly. Treat the granted access with care.
What it helps with
- review Starling Bank account details
- check transactions through an AI agent
- send a payment after configuring signing
Example prompts for the agent
- Review my Starling Bank account details.
- Check my Starling Bank transactions.
- Send a payment through Starling Bank after signing is configured.
