Works with Claude, ChatGPT, Cursor, and more
The Model Context Protocol standardizes how applications expose capabilities to LLMs. Instead of operating in isolation, your AI gains direct access to external platforms, live data, and real-world actions through secure, standardized connections.
This connection provides 9 powerful capabilities that interface natively with Claude, ChatGPT, Cursor, and other compatible AI platforms. No middleware. No custom integration required.
The pain of switching between systems is real.
Right now, checking your company’s financial health feels like a data scavenger hunt. You have to jump from the invoicing platform to check outstanding bills; then open your CRM to confirm client details; and finally toggle over to a separate expense tracker just to reconcile receipts. It's constant copy-pasting, clicking through dashboards, and waiting for three different systems to talk to each other.
With this MCP, all that friction disappears. You talk to the AI agent in one place. Need to know if an invoice was paid? Ask. Do you need a client ID checked against their tax status? Ask. The system runs the necessary checks and pulls everything into one answer.
The Billit MCP gives you control over your core financial data.
You no longer have to manually check if a client is properly logged before issuing a bill. You can use the agent to confirm party status via get_party and ensure all related products are listed using list_products, all in one chat sequence.
The result is clean, immediate action. The process isn't just faster; it's fundamentally more reliable because you're working with a single source of truth.
What your AI can actually do with this
Need to handle billing from a chat window? Billit connects your e-invoicing system to your preferred AI client so you can run complex accounting tasks using natural conversation. You ask for the information, and it happens. Your agent reads detailed invoices across the Peppol network, checks who your clients are, or pulls receipts into one summary.
This capability lets you handle everything from initial expense logging to generating a final bill in one go. Since Vinkius hosts this MCP, all these financial tools are available under one connection point for your AI client, meaning you don't need dozens of API keys just to manage your day-to-day books.

Here's how it actually works
The bottom line is you talk to your accounting system like talking to a person on the phone.
First, subscribe to the Billit MCP and enter your unique API key and desired environment (like 'api.sandbox') in Vinkius.
Next, connect this MCP to any compatible AI agent—your client does the rest.
Finally, you simply ask your agent what you need. It uses the tools available here to pull or create the data for you.
Who is this actually for?
This MCP is built for operations teams, bookkeepers, and small business owners who spend too much time switching between their CRM, expense tracker, and invoicing software. It’s for anyone whose job requires turning raw data—like receipts or client lists—into structured financial records.
Manages the flow of money by listing invoices to check payment statuses, and using tools like list_expenses to reconcile incoming receipts.
Needs to keep client records accurate; they use the MCP to create new parties or retrieve specific client details when setting up a contract.
Uses the system to pull detailed lists of all products and services, cross-referencing them against outstanding invoices for auditing purposes.
What Changes When You Connect
You stop jumping between tabs. Instead of logging into your CRM, then opening your accounting software to check on outstanding bills, you ask your agent directly for the status using list_invoices.
Creating new records is simple. Need a client? Just tell your agent to create_party; no need to manually fill out forms in another system first.
Expense tracking becomes instant. Instead of downloading spreadsheets and cross-referencing receipts, you simply ask to see all expenses using list_expenses.
Auditing pays off immediately. When you need proof on an old bill, your agent can pull the exact details for a specific invoice number with get_invoice.
Build better records by ensuring every new item is backed up. Before creating an invoice, checking available products via list_products keeps your billing accurate.
See it in action
Client asks why their bill was delayed
The agent checks the party details using get_party and cross-references that against the invoice status found by list_invoices. It then tells you exactly which payment stage caused the delay, giving you an immediate answer for your client.
Starting month-end reconciliation
The agent runs a query to pull all expenses using list_expenses. Next, it asks for a list of products and compares that against the expense categories to flag any non-standard costs before sending out reports.
Onboarding a new vendor
Instead of creating a profile in two different places, you just ask the agent to create_party. You confirm it's accurate, and the billing system is updated instantly for future payments.
The honest tradeoffs
Manual data gathering
Downloading a list of invoices from System A, opening an Excel sheet to match dates, then manually looking up client tax IDs in CRM B.
Ask your agent to run list_invoices and get_party. Your AI client handles the cross-referencing instantly. You just review the consolidated data.
Guessing which tool is best
Trying to use a general search tool that returns too many documents, forcing you to read through PDFs and web pages to find a single invoice number.
Use the specific get_invoice tool. Just providing the ID narrows down the result immediately to the exact bill details you need.
Forgetting preliminary checks
Jumping straight into create_invoice without first ensuring the client exists, which leads to an error and a delay while you track down the right party ID.
Always check or list parties with list_parties before attempting any creation. It ensures your foundational data is solid.
When It Fits, When It Doesn't
Use this MCP if your core pain point is coordinating three specific processes: billing, client management, and expense logging. If you need to create a bill and make sure the buyer exists in your books, this is what you want. Don't use it if all you need to do is read historical data; then simply using list_invoices or list_parties might be enough. However, don't try to use it as a general ledger tool. If you need complex, multi-year tax calculations that aren't tied to an invoice event, you need specialized accounting software, not this conversational interface.
Questions you might have
How do I create an invoice using the create_invoice tool? +
You simply tell your agent that you want to create an invoice, and it walks you through the required details like dates and line items. It handles the API call structure so you don't have to worry about JSON formatting.
Can I find out if a client already exists using list_parties? +
Yes, running list_parties gives you a full roster of all your current customers and suppliers. You can then use get_party with the name or ID to deep-dive into that one account.
What if I need details about an invoice before it's paid? +
Use the get_invoice tool. Just providing the specific invoice number lets your agent pull up all the billing details, including line items and payment history, without you needing to manually search through records.
Is list_expenses better than listing invoices for reconciliation? +
They track different things. Use list_invoices when you need to know what money was billed out; use list_expenses when you need to see the actual receipts and costs your company incurred.
When I use get_company_info, what kind of data must be provided for authentication? +
You need your Billit API Key and the correct environment (sandbox or production). You provide these credentials during the initial setup process; they are not included in the natural language prompt when you call the tool.
What should I do if a request to create_invoice fails with an error? +
Review the specific error message returned by the MCP. Failures usually relate to invalid API keys, missing required fields (like tax IDs), or incorrect data formatting for a specific parameter.
Does the list_products tool include pricing and tax information? +
Yes, it returns detailed product records. Each record includes the current price point and any necessary associated tax codes you need to know when generating an invoice.
How do I get full contact details after running list_parties? +
First, run list_parties to find the unique Party ID. Then, pass that specific ID into the get_party tool. This retrieves the complete set of contact and tax information for that single entity.
Can I check the payment status of a specific invoice? +
Yes! Use the get_invoice tool with the Invoice ID. Your agent will fetch the latest details and payment status (e.g., Draft, Issued, Paid).
How do I list all my customers in Billit? +
Simply ask the agent to list_parties. It will retrieve the directory of all companies and persons registered as customers or suppliers in your account.
Can I see recent expenses or receipts? +
Yes. Use the list_expenses tool to retrieve a list of all incoming invoices and receipts recorded in your Billit account.
