Give your AI client this address.
https://mcp.apiant.aiOne connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.
Setup guide (opens in a new tab)Keygen holds the licenses your software checks against; Lexware Office holds the invoices, quotations and contacts your accounting runs on. Joining them lets a new license raise the right document for the right contact, and lets a payment or a voided invoice in Lexware Office change the license state in Keygen without anyone retyping details.

Questions
Keygen and Lexware Office, answered
Can billing in Lexware Office change what happens to a license in Keygen?
Yes. A payment change or an invoice status change in Lexware Office can trigger Keygen actions such as Reinstate License or Suspend License, so an unpaid or voided invoice is reflected on the license. The agent tests each scenario before it goes live.
What if the customer is not yet a contact in Lexware Office when a license is created?
Find contacts in Lexware Office tells you whether a matching contact exists, so the run can stop or create the contact first instead of invoicing an unknown address. You decide which of those two scenarios applies, and both are tested.
What can start an automation from Keygen?
Any of Keygen's 13 triggers in the catalog, including License Created, License Expiring, User Created and New Event. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Lexware Office when something happens in Keygen?
Any of Lexware Office's 40 actions, including Create a contact, Create a quotation, Find contacts and Create a credit note. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Lexware Office to Keygen?
Yes. When something happens in Lexware Office, your agent can act in Keygen too. This page covers both directions: Lexware Office's triggers and Keygen's actions are listed here as well.
Do I have to build a connector for Keygen or Lexware Office?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Keygen and Lexware Office without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in either app once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
