custena CLI

Wrap any MCP server with payment middleware in two commands. No code changes required.

custena~2 min

Quickstart

npx custena init
custena wrap -- your-mcp-server

Your MCP server now charges per tool call. Set pricing in the dashboard — all payment protocols are accepted automatically.

`custena init`

Creates a custena.config.json in the current directory and walks you through:

Linking your Custena account (device flow, opens a browser)
Registering a new service — choose pricing, free-tier limits, and compliance settings
Generating a service-specific secret key

`custena wrap`

custena wrap -- your-mcp-server --your-flags

Everything after -- is forwarded verbatim to your MCP server's process. The CLI spawns your server, attaches the Custena middleware, and exposes a payment-enforcing endpoint on the port configured in custena.config.json (default: :4000).
