Atlarix 15.15: Connect Slack to Your AI Coding Agent

Slack is now in the Verified part of Atlarix's MCP list. Open the list (in the desktop app, Integrations → MCP; in the CLI, /mcp; in VS Code, the MCP servers command), pick Slack and press Connect. Your browser opens, you sign in to Atlarix if it asks, choose your workspace and allow it on Slack's page. That's the whole setup: no app to create, no token to copy.

Once connected, the agent has six Slack tools:

• List channels, including your direct messages, shown by the person's name.
• Read a channel and read a thread.
• Search messages across the workspace.
• Find a person by name.
• Post a message or a reply, as you.

So you can ask things like "summarise what the team said about the release in #general today" or "reply in that thread that the fix is on dev", from the same chat where the agent is working on your code. Step-by-step instructions are in Connect Slack in Atlarix.

The agent acts as you, in the workspace you picked, and sees only what you can see in Slack. Connecting installs the Atlarix Slack app in that workspace, and your Slack sign-in is stored encrypted on Atlarix's servers. It works in the desktop app, the CLI, VS Code and the editors that speak the Agent Client Protocol, such as Zed and JetBrains. Connecting Slack is free on every plan.

To ask @Atlarix for work inside Slack itself, rather than reaching Slack from Atlarix, see Atlarix in Slack.

MCP servers that sign in with OAuth now open their sign-in page in your browser from the CLI, Zed and JetBrains, not only from the desktop app. The CLI tells you when a sign-in worked, and why when it didn't.

A few rough edges are gone too. Retrying a sign-in you abandoned starts a fresh one, where it used to refuse with "already in progress". The page you land on after signing in no longer claims the tab will close by itself. An optional token box no longer stands in front of the sign-in button. And a connection added to your Atlarix account is now bound to your account and your browser while it signs in. How MCP works in Atlarix is in MCP servers.

Atlarix keeps notes per project, so a session remembers what matters about the code it's working on. In 15.15 a session reads, lists and searches only its own project's memory, whether it uses its file tools or a shell command, on macOS and on Linux. Reading the memory file before any note exists says so, where it used to show an error.

A message also never waits for memory recall any more. The turn starts at once, and a note found a moment later joins the next step.

Commands the agent runs go through a sandbox. The Linux CLI now carries its sandbox helper inside the binary, so a CLI installed with the one-line installer or npm has it too. On Ubuntu releases that block the fallback sandbox, Atlarix says the sandbox isn't available, where it used to fail the command.

The agent can schedule itself to come back to a task later. Those wake-ups are now listed in Automations in the desktop app, and in the CLI status line, each with a Cancel button.

When you press Stop in the middle of a tool call, that call now reads "Stopped" (the CLI says "interrupted"). It used to look as if it had finished.

• A session's name follows the work when you approve a plan or hand a task over.
• The context meter drops right after /compact and shows the right size when you reopen a session.
• Sending a message to a session name that matches nothing lists the sessions that are live.
• The search icon inside a workspace searches that workspace's chats, and chat search shows why a chat matched.
• In the CLI, a typed path to an image is attached as if you'd pasted it, each waiting message gets its own row (ctrl+o shows it in full), and tmux gets the window title and bell.
• The VS Code panel says "Starting Atlarix…" while it starts.

The desktop app and the CLI update themselves to 15.15 (a Linux .deb or .rpm takes the new package from the downloads page). To install fresh:

• Desktop app: download it for macOS, Windows or Linux from atlarix.dev.
• CLI on macOS or Linux: curl -fsSL https://atlarix.dev/install | sh
• CLI on Windows (PowerShell): irm https://atlarix.dev/install.ps1 | iex
• CLI with npm: npm install -g atlarix
• VS Code, Cursor, Kiro or Windsurf: search for "Atlarix" in the VS Code Marketplace or on Open VSX. Details are on the extension page.

The app, the CLI and the editor extension share one account, so a chat started in one is there in the others. New to Atlarix? Start with Getting started.
