AI assistants such as ChatGPT and Claude can now work inside the tools a business already uses. The open standard behind this is the Model Context Protocol (MCP): a subscription platform publishes an MCP server, and any assistant that supports remote MCP servers can connect to it with the merchant's permission.

What an assistant can do with subscription data

• Answer questions from live data: "Which subscriptions renew this week?", "What did subscription movement look like last month?" or "Which SKUs are selling fastest?"
• Look up a customer: Find a subscriber and read their subscriptions, orders and shipments before replying to them.
• Hand off real work: Ask the platform's own agent to make a change, with approval before anything consequential happens.

The safety questions to ask any vendor

• Whose permissions does the assistant use?: It should act as the person who connected it, with their access, and lose access when that person is removed.
• Can it change things without approval?: Reads are low-risk. Changes to billing, subscriptions and orders should go through an approval step.
• Can you see and revoke connections?: Every connected assistant should be listed in the admin, and disconnecting should stop access immediately.
• How is it authenticated?: Look for OAuth sign-in rather than pasted API keys.

How the Chargezen MCP server answers them

• One workspace per connection. The assistant acts as the teammate who connected it, and Chargezen checks that teammate's access on every request.
• Read tools cover subscriptions and subscription plans, a subscription movement report, customers, products, sales by SKU, inventory, fulfillment status, shipments and workspace knowledge.
• Every change goes through Concierge, Chargezen's AI agent, which asks you to approve consequential actions before taking them.
• Teammates can see and disconnect every connected assistant under Concierge → Deploy → Channels → External MCP servers. Disconnecting stops access immediately.
• Sign-in uses OAuth 2.1 with PKCE. No pre-registration or API key is needed.
• Reading data does not use credits. Work you ask Concierge to do uses workspace credits when it runs on Chargezen-managed AI models.

Set it up in two minutes

• In ChatGPT, Claude or another assistant that supports remote MCP servers, add a custom connector with the server URL https://mcp.chargezen.com/mcp.
• Sign in to Chargezen when the assistant asks.
• Choose the workspace, review what the assistant may do, and select Allow.
