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

Installation

Step 1: Create a Starling Bank personal access token. To do this:

• Sign up for a Starling Developers account

• Link your Starling Bank account to your Starling Developer account

• Create the access token

  • The token name can be anything, e.g. 'Starling Bank MCP Server Token'

  • Select the scopes based on what you want the AI system to be able to access

Keep the token handy, you'll need it in the next step. It'll probably begin something like eyJhbGciOiJQUzI1NiIsInppcCI6IkdaSVAifQ., and be moderately long.

Step 2: Follow the instructions below for your preferred client:

• Claude Desktop

• Cursor

• Cline

(Optional, Advanced) Step 3: See PAYMENT_SIGNING_SETUP.md if you want to be able to send payments.

Claude Desktop

(Recommended) Alternative: Via manual .mcpb installation

1. Find the latest mcpb build in the GitHub Actions history (the top one)

2. In the 'Artifacts' section, download the starling-bank-mcp-mcpb file

3. Rename the .zip file to .mcpb

4. Double-click the .mcpb file to open with Claude Desktop

5. Click "Install" and configure with your API key

(Advanced) Alternative: Via JSON configuration

1. Install Node.js

2. Open Claude Desktop and go to Settings → Developer

3. Click "Edit Config" to open your claude_desktop_config.json file

4. Add the following configuration to the "mcpServers" section, replacing eyJhb... with your API key:

{
  "mcpServers": {
    "starling-bank": {
      "command": "npx",
      "args": [
        "-y",
        "starling-bank-mcp"
      ],
      "env": {
        "STARLING_BANK_ACCESS_TOKEN": "eyJhb...",
      }
    }
  }
}

5. Save the file and restart Claude Desktop

Cursor

(Recommended) Via one-click install

1. Click

2. Edit your mcp.json file to insert your API key

(Advanced) Alternative: Via JSON configuration

Create either a global (~/.cursor/mcp.json) or project-specific (.cursor/mcp.json) configuration file, replacing eyJhb... with your API key:

{
  "mcpServers": {
    "starling-bank": {
      "command": "npx",
      "args": ["-y", "starling-bank-mcp"],
      "env": {
        "STARLING_BANK_ACCESS_TOKEN": "eyJhb..."
      }
    }
  }
}

Cline

Via JSON configuration

1. Click the "MCP Servers" icon in the Cline extension

2. Click on the "Installed" tab, then the "Configure MCP Servers" button at the bottom

3. Add the following configuration to the "mcpServers" section, replacing eyJhb... with your API key:

{
  "mcpServers": {
    "starling-bank": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "starling-bank-mcp"],
      "env": {
        "STARLING_BANK_ACCESS_TOKEN": "eyJhb..."
      }
    }
  }
}

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.
