2FA Handling

The server handles two-factor authentication gracefully:

• If COINBASE_2FA_CODE is set, it will be used automatically
• Otherwise, the server waits up to 60 seconds for you to complete 2FA in the browser
• The browser session is reused across tool calls to minimize repeated logins

Browser Automation

This package uses Playwright with stealth mode (via playwright-extra + puppeteer-extra-plugin-stealth) to automate the Coinbase web interface. This approach:

• Works with Coinbase's standard web UI
• Handles dynamic page content
• Bypasses basic bot detection via stealth plugin

Development

git clone https://github.com/markswendsen-code/mcp-coinbase
cd mcp-coinbase
npm install
npx playwright install chromium
npm run build

Run in dev mode (with tsx, no build step):

npm run dev

Security Notes

• Never commit your Coinbase credentials to version control
• Use environment variables for all sensitive configuration
• The confirm: false default on buy/sell prevents accidental trades
• Review all trades carefully before setting confirm: true
