The Current Headache: Tracking Down Billing Details
Right now, getting a full picture of one user is a painful click-through process. You have to jump from the main customer dashboard to the subscription tab, then maybe open another window just for invoices. If you need to know if they are paying correctly and what features they use, it's easy to miss something or get lost in the tabs.
With this MCP connection, that whole process disappears. You simply talk to your agent: 'What's going on with customer c_1?' The agent pulls together all the data—the plans, the invoices, and their details—and hands it back to you in one simple, conversation-ready response.
Billsby MCP gives you control over your entire billing lifecycle.
You don't have to worry about manually checking if a new account needs setup or what the current pricing is. You can use `create_customer` for signups and check available plans using `list_plans`, ensuring consistency everywhere.
Billing data used to live behind walls of dashboards and APIs. Now, it flows into your agent's conversation. It's simple, direct, and always up-to-date.
What your AI can actually do with this
Managing recurring billing used to mean jumping through hoops: logging into the platform, navigating specific tabs, and copying details just to answer a simple question. This MCP changes that. You can now talk to your AI client and ask it things like, 'What was Jane Smith's last invoice amount?' or 'Does this customer have an active Enterprise plan?' Your agent handles all the API calls in the background.
It pulls up current user data, checks subscription status, and even lists available add-ons—all through natural conversation. Need to check historical billing records? You can get that too. Because Vinkius hosts this MCP, your AI client connects once and gets access to everything needed for a full audit trail.

Here's how it actually works
The bottom line is you get real-time, conversational access to data that used to require multiple dashboard logins.
Subscribe to this MCP and provide your Billsby API Key along with your Company Domain.
Connect your preferred AI client (like Cursor or Claude) to the Vinkius catalog.
Ask your agent a billing question—for example, 'List all customers whose invoices are overdue.' — and it executes the calls.
Who is this actually for?
Support teams who are tired of logging into three different systems just to answer a customer's billing question. Finance operations staff who need quick audit checks on invoices, and SaaS founders managing daily user growth.
When a user calls asking about their plan, you check the current active plans or retrieve the full billing history instantly.
You run quick audits to list all invoices and confirm payment statuses before month-end closing.
You quickly check the total count of users or see what new products are available for upsells without opening the main dashboard.
What Changes When You Connect
Stop copying and pasting customer IDs. You use the get_customer tool to pull up a user's profile and instantly check their active subscriptions or full billing history.
Run instant audits across your client base. Instead of manually checking dashboards, you ask for a list of invoices and get immediate status updates using list_invoices.
Need to onboard someone fast? You can use the agent to create new accounts with create_customer, logging the user data without needing admin access to the portal.
Always know your upsell options. The MCP lets you pull product lists and available add-ons, so you're ready when a client asks for more features.
It organizes complex billing logic into simple conversation flow. Your agent handles the complexity of checking multiple plans or listing all subscriptions through list_subscriptions.
See it in action
A Support Agent needs to check a user's plan.
The customer calls saying they think their rate is wrong. The agent asks the AI client to use get_customer_subscriptions for that ID, immediately confirming if they are on the correct tier and when it expires.
Finance needs a quick revenue snapshot.
Before running month-end reports, the finance team asks their agent to execute list_invoices. This quickly confirms how many invoices are paid versus overdue without navigating the billing portal.
Sales wants to check product availability.
A sales rep talks to their client and needs pricing info on a new feature. They ask the agent to use list_products to get real-time pricing, making the conversation accurate right then.
Product Manager is planning an upsell.
The PM wants to see what extra features they can sell. They prompt their agent using list_addons, which instantly provides a catalog of available add-ons and their associated costs.
The honest tradeoffs
Trying to check billing data manually.
Logging into the Billsby website, finding the customer ID in one tab, then switching tabs to find the invoice history, and finally checking a third section for available plans. It takes 15 clicks and three browser windows.
Just ask your agent to 'Show me all billing data for this user.' The MCP handles querying get_customer, list_invoices, and get_customer_subscriptions in one go.
Assuming the tools are separate.
Trying to find out if a customer's current subscription is related to an add-on without knowing how to cross-reference the data.
Ask your agent to check both the list_subscriptions and then specifically call get_customer_subscriptions. The MCP links them for you.
Writing a script that only handles one task.
Building a dedicated Python function just for listing customers, which fails if they need to check payments next. It's brittle and siloed.
Use the Vinkius catalog connection. Your agent can chain multiple calls—like list_customers followed by checking their invoices—in one natural conversation.
When It Fits, When It Doesn't
Use this MCP if your primary need is to query or modify core billing records, such as customer data, subscription status, or invoice history. You'll use it for anything that requires read/write access across the entire user lifecycle. Don't use it just because you want a simple contact list; if all you need is a name and email, a simpler CRM tool might suffice. But if you need to know what they paid or if their subscription expired, this MCP is necessary. If your goal is pure data analytics (e.g., calculating lifetime value from raw transaction logs), then an external warehouse connection would be better; use the list_invoices and get_customer tools if you need to pull structured, clean data points for that analysis.
Questions you might have
How do I list all customers using the Billsby MCP? +
You trigger the list_customers tool. This gives you a clean manifest of every account currently in your billing system, which is great for quick audits.
Can I check an invoice's payment status with the Billsby MCP? +
Yes, use list_invoices. You can ask to see recent invoices and whether or not they have been marked as paid by your client.
Do I need the get_subscription tool for everything? +
Not necessarily. While get_subscription gives deep details on one plan, you might prefer using list_subscriptions if you want a broader overview of every active service.
What if I need to create a new customer account? +
Use the create_customer tool. This executes the creation process directly, letting your agent handle the API call for you.
If I only know a customer's ID, how do I use the `get_customer` tool to retrieve their specific details? +
The get_customer tool fetches all core data for one user. You just pass the unique customer identifier when invoking the function. This is fast and lets you verify account information without needing a list view.
How do I use the `list_plans` tool to see every available pricing tier? +
Running list_plans gives you a complete overview of all defined subscription models. This is useful for checking your product catalog or comparing different service levels before making recommendations.
I need to know about extra features; what does the `list_addons` tool do? +
The list_addons tool retrieves all available add-ons that can be attached to a core subscription. This lets you check compatibility and pricing for extras your customers might want.
What is the difference between checking one customer's subs using `get_customer_subscriptions` and running `list_subscriptions`? +
Using list_subscriptions shows an account-wide view of every active billing record. Meanwhile, get_customer_subscriptions filters that list down to show only the plans tied to one specific customer.
Can I check which subscription plan a customer is currently on? +
Yes! Use the get_customer_subscriptions tool with the Customer Unique ID. It will fetch all active and inactive plans for that user.
Does the integration allow me to cancel a subscription? +
Currently, the toolset focuses on querying and management functions (listing customers, checking invoices). Canceling or modifying subscription billing dates must be done on the Billsby platform.
Can I list all available subscription plans? +
Yes. Use the list_plans tool to retrieve all subscription plans configured in your Billsby account, including their pricing and cycles.
