Add Subbly as a custom connector
Cowork uses the connectors on your Claude account. If you've already added Subbly in Claude, it's in Cowork too. Adding the key needs request headers, a beta Anthropic is rolling out to more accounts.
Open Connectors and add a custom connector
In Claude, open Customize, then Connectors, and choose Add custom connector. On a Team or Enterprise plan, an owner adds it under Organization settings, Connectors.
Name it Subbly and paste the server URL
Server URLhttps://mcp.subbly.dev/mcpChoose No sign-in, then add your key as a request header
Under Request headers, add X-API-KEY with your key as the value. No Request headers section? Your account doesn't have the beta yet. Until it does, Claude Code connects with your key today.
Request headerX-API-KEY: YOUR_SUBBLY_API_KEYSwitch it on in Cowork
Open the Cowork tab in Claude Desktop, then Customize, Connectors, and turn Subbly on.
Check it worked. Ask Cowork to list your published Subbly products. It asks before it uses Subbly the first time.
Why connect Cowork to Subbly
Hand over the long jobs
Weekly reports, catalogue reviews and order checks run while you get on with your day, and the results land in your files.
No terminal, no code
Subbly is a connector in Claude's settings, so you set it up with a URL and a header, then ask in plain English.
Shared with Claude
The connector you add is on your Claude account, so the same Subbly connection works in chats and in Cowork.

Artifacts
Turn your store into dashboards, plans and documents
Agents that make artifacts, like Claude, work between your store and everything else. They pull the real numbers from Subbly and turn them into something you can share, print or act on.
Pull my active Subbly subscriptions and build an interactive dashboard: subscribers by plan, new this month, and cancellations by reason.

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 Cowork?
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 Cowork its own key, so you can delete it without breaking anything else.
Is Claude Cowork the same as Claude Code?
No. Cowork is Claude Desktop's agent for longer tasks on your files and apps, with no terminal. Claude Code is Anthropic's coding agent for the terminal and IDE. Both can connect to Subbly, in different ways.
Do I need a terminal or any code to use Subbly in Cowork?
No. You add Subbly as a connector in Claude's settings, paste the server URL and your key, and switch it on.
Why can't I see Request headers?
Sending a key in a request header is a beta that Anthropic is rolling out to more accounts. Until your account has it, Cowork can't send Subbly your key. Claude Code connects with a key today, and Claude Desktop can use its config file.
Is it safe to give Cowork 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. Cowork 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 Cowork 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 Cowork will be able to change your pages too.
Which Subbly plans work with Cowork?
Every plan includes the MCP server, with usage limits that depend on your plan.
