How to connect Claude Code to your team's chat so it answers @mentions

Claude Tag (Slack, Team and Enterprise plans)

Claude Tag is "Claude working in your team's Slack channels". [1] It's in public beta. [1]

• Pick it if your team wants one shared @Claude that anyone in a channel can hand work to, with access set by an admin.
• Who sets it up. An Owner of a Claude organization on a Team or Enterprise plan runs setup, together with a Slack workspace admin, who runs @Claude connect and passes the pairing code over. It isn't available on Free, Pro, Max or Ultra. [1]
• Where the work runs. Each thread gets its own session, and "the work runs in an ephemeral cloud sandbox, not on your local machine." [2] For code, Claude clones your GitHub repositories into the sandbox and pushes back a branch or pull request. [2]
• Whose identity. In channels, Claude acts under its own service accounts that an admin provisions, not as the person who asked. Access is set per channel. [2]
• Add it to a channel with /invite @Claude. [1]

Claude Code in Slack, the earlier app (Pro, Max and Ultra)

Anthropic's docs call this "the earlier Claude Code in Slack". [3]

• Pick it if you're on a Pro, Max or Ultra plan and you want to start cloud coding tasks from a Slack thread.
• It answers channel @mentions "only from Pro, Max, and Ultra accounts, and only in a Slack workspace that no organization has connected to Claude Tag." [3]
• Each session "runs under your own Claude account, using your connected repositories and your plan limits." [3] A coding request creates a Claude Code cloud session on claude.ai/code. [3]
• It works in public and private channels, not in DMs. You add it with /invite @Claude. [3]
• Repositories must be on GitHub, and each session can open one pull request. [3]

Your own Slack bot

If neither fits, a Slack app can subscribe to the app_mention event, which delivers "only the message events that mention your app or bot" and needs the app_mentions.read scope. [4] Your handler then runs Claude Code non-interactively with claude -p "<the message>". [5]

• Set what the agent may do without asking with --allowedTools, or with a permission mode such as --permission-mode dontAsk. In a manual-mode -p run, a call that needs approval is denied unless something approves it. [5]
• Use --output-format json to get the reply text back in the result field, ready to post into the thread. [5]
• In scripts, --bare skips the host's hooks, plugins, memory and CLAUDE.md, so every run starts the same. Bare mode doesn't use your Claude login, so set ANTHROPIC_API_KEY. [5]
• You host and secure the bot yourself. Slack messages become prompts, so keep the allowed tools narrow. Anthropic warns that Claude "may follow directions from other messages in the context" of a Slack thread. [3]

Each teammate's own Claude Code, in one pod (Commonly)

The options above give the team one @Claude. In Commonly, each teammate brings their own agent into one pod, and people and agents share the same conversations and one task board. Each agent is a named member with an owner, so everyone sees whose agent did what. [6]

Claude Code answers @mentions on a Mac, and on Linux in invite-only pods. On Windows it connects over MCP but doesn't answer @mentions. Codex answers on a Mac. [6]

1. Create a pod and invite your teammates with the invite link.
2. Each teammate opens Bring your own, then Use my own agent, then Get my connect command, and runs it to bring their own Claude Code. On a Mac, it then answers @mentions in the pod. Codex on a Mac connects the same way.
3. Mention a teammate's agent by name. It runs on its owner's machine, with that person's checkout and settings, and replies in the pod.

Or start a hosted agent

You can also start a hosted agent in the pod with one click. Hosted agents answer in the pod but don't claim tasks on the board.

Which to pick

• One shared @Claude for the whole Slack workspace, admin-managed: Claude Tag. [1][2]
• You alone, on a Pro, Max or Ultra plan, starting cloud tasks from Slack: the earlier Claude Code in Slack app. [3]
• Full control, and you'll run the service: your own bot calling claude -p. [4][5]
• Each teammate's own agent on their own Mac, answering in one shared space with a task board: Commonly. [6]
