An assistant is only as good as its data. Ours is real time, from day one.
Connect an assistant to messy payables and you get confident answers that are quietly wrong. The reasoning is fine, the ground truth is not. So we split the problem: Claude answers in plain words, Cortena builds the part you cannot leave to chance.
Claude understands the question and replies in plain language, over your own data. That part is genuinely good.
Cortena delivers clean, booking-ready data. Right entity, right accounts, right cost centre, right VAT. Same invoice, same result, every time.
Right from the first minute
Invoices are captured and pre-booked as they arrive, so the data is booking-ready from the moment it lands.
Real time
Invoices are pre-booked in seconds. Often the answer is ready before you finish asking.
Same rules, every time
Every invoice coded, every line booked, on your rules. The same invoice gives the same result, not a fresh guess each run.
Answers on truth
Claude reasons over correct financial data, not a spreadsheet you hope still holds. That is the difference between guessing and knowing.
The Cortena MCP server, answered.
The Cortena MCP server is a Model Context Protocol endpoint at app.cortena.ai/api/mcp that lets an AI assistant read and act on your accounts payable. You add it to Claude as a custom connector, then ask about your invoices, metrics and queues in plain language.
You can connect any assistant that supports custom MCP connectors, starting with Claude. You point the client at app.cortena.ai/api/mcp and authorise it over OAuth, scoped to your Cortena workspace.
You can list and search invoices, read your Pulse dashboard metrics, check workflow queues, and get deep links back into the app. The assistant answers from your live Cortena data, filtered to what your account is allowed to see.
Not by default. Connectors are read-only unless you grant a client write access. When you do, writes follow a prepare, confirm and commit flow, so nothing is changed until you approve the exact action.
Yes. Every request is scoped to your tenant and permissions, all activity is logged, and clients connect over OAuth so you can revoke any of them at any time. Data is hosted in the EU and is never used to train AI models.
The MCP server is in beta. It is available to Cortena customers who want to connect their assistant, and we are expanding coverage of tools and clients. Book a demo and we will set up a connector for your workspace.
