StablecoinX

StablecoinX merchant MCP server that lets an assistant handle auth, payments, paymaster, webhooks, floYsh sites and vault settings from a local process.

What you can do

• Manage merchant authentication and login sessions
• Create and handle stablecoin payments and paymaster operations
• Configure webhooks for merchant events
• Set up and manage floYsh sites
• Adjust vault settings
• Keep encrypted local state for tokens and session keys

When to use it

Use it when you are a StablecoinX merchant and want an assistant to drive payment, paymaster, webhook, site and vault configuration tasks instead of clicking through the dashboard.

Requirements

Runs locally over stdio via npx from the npm package, on desktop only. Requires the SCX_STATE_PASSPHRASE secret to encrypt local state; SCX_STATE_DIR optionally sets where that state file lives. The harness endpoint, thirdweb client, origin and login chain are built into the package.
