AIUS can work with the services and data you already use: GitHub, Linear, Notion, Slack, a database, a calendar and many more. It reaches them through connections (MCP servers). You don’t install or configure anything yourself: tell the agent what you want to connect.

​
Connect something

Ask in plain words, for example:
  • “Connect GitHub so you can read the issues for this project.”
  • “Connect our Postgres database at localhost so you can query the orders table.”
  • “I’d like you to read my Notion notes.”
The agent then:
  1. Looks for a connection in the public MCP registry, and on the web when the registry has nothing suitable.
  2. Tells you what it found, who runs it and what it can read or change, and what you need for it, such as an access key and where to get one. It asks in the conversation only for things that are not secret, such as the name of your workspace.
  3. Asks your approval before it connects, showing exactly what will run on your computer or which address it will connect to.
  4. Asks you to paste each key or password into a hidden field in the terminal (see Keys and passwords).
  5. Connects it, checks it with one call that only reads, and uses it straight away, in the same conversation.
You don’t have to ask first. When your question needs data from a service or database you mention or plainly use, such as a CRM, analytics, ads, Postgres, Notion, Google Sheets, Stripe, HubSpot or Slack, the agent proposes connecting it and leads you through it: what the connection can read or change, numbered steps to create the access key with read-only permissions in that service, and the hidden field to paste it in. It checks the connection with one read-only call and then answers your question with it. If something fails, such as a rejected key or missing permissions, it says what went wrong and how to fix it. It connects nothing until you approve the connection. The agent prefers the service’s own connection, where you sign in with the service and nothing runs on your computer. When only someone else’s connection is available, it tells you who runs it, because that server sees everything that passes through it, and it gives it no key without your yes. Some connections are small programs that run on your computer instead; the approval prompt shows the exact program before anything starts. For a database on your computer or your network, the agent picks one of those, since a hosted connection could not reach it. Each service gets a connection of its own, named after it. The agent replaces an existing connection only when you ask, and the approval prompt then says which one it replaces. Once connected, tools the service marks as read-only run freely. Any other tool may change data in the service or send data out, so it asks for your approval first; see Approvals.

​
Google Drive, Sheets and Docs

Google lets only registered apps sign in to Drive, Sheets and Docs. So the agent first offers the simple ways: download the files into your project folder (File > Download for a Sheet or Doc), or read files such as CSV and Excel from the Google Drive for desktop folder on your computer. Sheets and Docs appear in that folder only as links, so download those first. If you want a live connection, it walks you through registering an app in Google Cloud and connecting it.

​
Signing in

Many services ask you to sign in and approve access. AIUS opens the sign-in page in your browser and finishes connecting as soon as you approve. When no browser can open, for example on a remote computer, the sign-in link appears in the conversation and in a notice, and is copied for you. Open it in a browser on the computer that runs AIUS within five minutes. If the link runs out, ask the agent to connect the service again.

​
Keys and passwords

Once you approve a connection, AIUS asks for each key or password it needs in a hidden field in the terminal: the name of the key, where to get it, and a field that shows a dot for each character and how many there are, never the key itself. What you paste goes straight to a private file on your computer that only your user can read. It is never written into your AIUS settings, and it never goes into the conversation: the agent, the model, AIUS Light and the logs never see it. Don’t paste a key into the conversation itself; everything you type there is sent to the model. When you follow the conversation in the browser, AIUS Light says which key to paste in AIUS on which computer. There is no field for it in the browser. Keys given to a connection are also left out of the copy of the conversation that AIUS Light keeps and your other computers receive.

​
The MCPs list

Type /mcps to see every connection and whether it is connected, waiting for you to sign in, turned off or failing. Add a connection… at the end of the list asks what you want to connect and hands the request to the agent. AIUS Light, the connection to the web platform, comes with your AIUS sign-in. It is always on and can’t be removed. You can also manage connections in the conversation: “What’s connected?”, “Turn off the Slack connection”, “Remove Notion”.

​
Change how AIUS works

Your preferences are changed the same way, by asking:
  • “Always ask before running shell commands.”
  • “Use Claude Opus 5.5 as the default model.”
  • “Read notes.md as instructions in every conversation.”
  • “Don’t share conversations automatically.”
The agent shows the change for your approval and saves it for every folder. Changes to a connection apply immediately; other settings apply the next time you start AIUS. To switch the model for the conversation you are in, ask the agent or use /models. Models always come from the AIUS catalog; see Models.
