Built by Subbly

Describe your store. Your Subbly agent builds it.

Your website, checkout and customer portal are designed and built by your Subbly agent, around your brand. Site editing through MCP is coming soon, so the agent you already use will be able to change your pages too.

See what it builds

Not through MCP yet

Coming soon

Design or edit your website (your Subbly agent does that, and site editing through MCP is coming soon)
Set up funnels, automations, dunning or the referral program
Read analytics reports (it can pull the raw orders and subscriptions to work them out)

You set those up in your Subbly admin.

Frequently asked questions

Where do I find my Subbly API key for Grok Build?

In your Subbly admin, open Settings, then API keys (https://www.subbly.co/admin/settings/api-keys). In the Private API keys card, choose Generate API key and copy it. Only the store owner and admins can create keys, and Subbly asks for two-factor authentication first. Give Grok Build its own key, so you can delete it without breaking anything else.

I already set Subbly up in Claude Code or Cursor. Do I need to add it again?

Usually not. Grok Build also reads the MCP servers in ~/.claude.json, .cursor/mcp.json and .mcp.json, so Subbly shows up there too. Run grok mcp list to check.

What's the difference between Grok Build and Grok Bot?

Grok Build is xAI's coding agent for your terminal. Grok Bot is a cloud agent from Cursor and xAI that works on its own computer and is set up by sending it a message. Both can connect to Subbly.

Does this work on grok.com or in the Grok app?

grok.com's custom connectors haven't been confirmed with an API key yet. Use Grok Build or Grok Bot, which connect today.

Is it safe to give Grok Build my Subbly API key?

The key can read and change everything in your store, so treat it like a password and keep it out of files you share or commit. Grok Build asks before running a tool unless you allow it, and Subbly's tools tell the agent to confirm with you before archiving or deleting anything. If a key leaks, delete it under Settings, API keys, and it stops working straight away.

Can Grok Build build my website through Subbly's MCP server?

Not yet. The MCP server runs your store: products, plans, subscriptions, orders, customers and coupons. Your website is built by your Subbly agent: describe it in Subbly and it designs and builds the store, checkout included. Site editing through MCP is coming soon, so Grok Build will be able to change your pages too. Until then, Grok Build can build a custom storefront in code that checks out with the SubblyCart.js widget.

Which Subbly plans work with Grok Build?

Every plan includes the MCP server, with usage limits that depend on your plan.
