Nia CoreNia Core Agent is a small program your IT team runs on a machine inside your own network. It lets Nia Core read your databases and deliver data without your database ever being reachable from the outside. Here is the whole journey, in five steps.
An admin, owner, or member with access to this workspace opens the Agents page and clicks "Add agent." This creates a one-time pairing code to hand to whoever runs the install on the machine.
From the downloads page, get the package for your operating system and run it. See the install guide for your OS for the exact click-through steps.
The installer walks you through a short set of questions: your pairing code, your database's server address and port, a username and password for it, which databases to read, and your timezone. See Connect a database for what to have ready beforehand.
Once the agent starts, it shows up on the Agents page as online within a few seconds. That confirms the pairing worked and the platform can reach it.
On the Canvas, add a "Local database (via agent)" connection, pick a table, map its fields, choose a destination, and publish. See Use a local database on the Canvas.
