Create Kadaster database

In this step, we set up a database with data from Kadaster. The database is "virtual" because it is not a traditional database, but is fed real-time from Kadaster. Invantive Cloud provides Claude with a real-time link to Kadaster. The database will be used for all your Kadaster reporting with Claude. So you only need to perform these steps once.

  1. Click the Add Database button. Add database.

  2. Select Kadaster from the list. Select Kadaster connector.

  3. Please fill out the form with login information for Kadaster.

  4. Select the OK-button.

Congratulations! You can now process data from Kadaster within the Invantive Cloud website. You can do this for example with the interactive SQL editor.

Grant connection from Claude access to Kadaster

To retrieve the data from Claude we create a link via Invantive Bridge Online. This creates a "bridge" between the cloud of Invantive and the standard OData connector that is available in every version of Claude. You do not need to install anything locally: no connector, no ado.NET provider and no Claude add-on neither.

Execute the following steps to safely use the data from Kadaster outside of Invantive Cloud:

  1. Next to the database you will find an orange text requesting you to allow access from your current location (IP address). Select the nearby orange button.

  2. You can completely disable IP address checking by entering an asterisk ("*").

You are now ready to import the Kadaster data into Claude.

What Claude Can and Cannot Do

The connector offers tools such as to describe the data model and read records. There is no tool that writes, posts, deletes or executes SQL, so no instruction in a conversation can change anything in Kadaster.

Reading is bounded by the database: platforms not in it and Kadaster companies not selected are not reachable.
