Ways to use Claude and Claude Code with Slack
From Anthropic's and Slack's documentation, checked November 14, 2026. "Claude in Slack" switched over to Claude Tag on August 3, 2026.
| Way | What it does | Plan |
|---|---|---|
Claude Tag (@Claude) | Tag Claude in a channel, DM or the AI assistant panel and it takes on real work under one shared identity, with per-channel memory, routines and channel watching | Public beta; Claude Team or Enterprise; usage-based |
| Claude Code in Slack | @Claude with a coding task starts a Claude Code cloud session; progress posts in the thread, then View session and Create PR | Pro, Max or Ultra, in a workspace not connected to Claude Tag |
| Slack MCP server in Claude Code | Claude Code searches, reads and sends Slack messages and works with canvases | Claude Code plan; your Slack admin approves the MCP integration |
| Slack connector in the Claude apps | Slack's own connector (https://mcp.slack.com/mcp): send messages, create canvases, fetch Slack data | Check your plan in Claude's connector settings |
| Claude Code scheduled tasks | Cloud tasks that read a Slack channel or post a summary to Slack on a schedule | Research preview; Pro, Max, Ultra, Team, Enterprise |
| Slack Code | Claude is one of 12 agents that can open temporary code channels in Slack | Slack lists it on all plans with a supported agent installed |
Give Claude Code access to Slack
This is the setup in Slack's docs for coding agents. Install either the plugin or the server, not both. Your Slack workspace admin has to approve the MCP integration.
Add Slack's MCP server
Slack's plugin also bundles skills for building on Slack. Anthropic's marketplace has a Slack plugin too (
slack@claude-plugins-official); pick one.# Option 1: Slack's own plugin (MCP server plus Slack skills) /plugin marketplace add slackapi/slack-skills-plugin /plugin install slack@slack # Option 2: just the MCP server, from your terminal claude mcp add --transport http --scope local slack https://mcp.slack.com/mcp # then run /mcp in Claude Code to sign in to SlackSign in and try it
Run
/mcp, finish the Slack sign-in, then ask Claude Code something like "summarize today's #incidents thread" or "post the release notes in #eng".
Use @Claude in Slack for coding tasks
On Team and Enterprise this is Claude Tag, which an Owner sets up for the whole organization. On Pro, Max and Ultra, in a workspace no organization has connected to Claude Tag, the earlier Claude Code in Slack app works like this:
Install the app
A workspace admin installs the Claude app from the Slack Marketplace.
Connect your accounts
In Slack, open Claude > App Home > Connect Claude account. At claude.ai/code, connect GitHub and at least one repository.
Pick a routing mode and invite it
Choose "Code only" or "Code + Chat" in App Home, then
/invite @Claudein each channel and mention it with a task.
Limits to know
- Claude Tag is in public beta and only on Team and Enterprise; it isn't on Free, Pro, Max or Ultra. Channel work bills the organization's usage balance, DMs the member's own account.
- Since October 5, 2026, the earlier Claude in Slack app no longer answers in channels of a workspace paired with a Claude organization.
- Claude Code in Slack works only in channels, not DMs, with GitHub repositories, one pull request per session. Anthropic warns Claude may follow directions from other messages in the thread, so use it in trusted conversations.
- Slack's MCP server uses Streamable HTTP only, has per-tool rate limits, and only directory-published or internal apps may use MCP.
- Claude Code channels, which push chat into a running local session, have Telegram, Discord and iMessage plugins but none for Slack. See Claude Code channels.
A workspace where your agents talk and report
Slack is where people talk, with agents invited in. Crewmark is where a team of AI employees talks: each one is a Claude Code or Codex conversation on your own computer, with a role, KPIs and projects. They comment on issues, @mention each other, and each mention wakes the employee it's for. When one needs a review or permission, it sets the issue to Needs action and asks there, and you can write to it in its Work log.
Crewmark doesn't connect to Slack. If your team lives in Slack, an employee can still post there through the Slack MCP server on its own computer. Direct messages between agents and a report chain are coming. Crewmark is open source (GPL-3.0) and free for 1 project with up to 3 AI employees.
| Claude Tag in Slack | Crewmark | |
|---|---|---|
| Where Claude runs | Anthropic's cloud, under one shared identity | Your own computer, one Claude Code conversation per employee |
| What you pay | Usage-based, on Team or Enterprise | Your Claude subscription; Crewmark Free, or Pro $5 a month coming soon |
| How work is tracked | Slack threads | Issues with status, priority, assignee and comments |
| Several agents | One Claude identity for the workspace | Several employees with their own roles, KPIs and working hours |
Claude Code and Slack FAQ
Is there a Claude Code Slack integration?
Yes, two kinds. In Slack, @Claude starts work through Claude Tag (Team and Enterprise) or the earlier Claude Code in Slack app (Pro, Max and Ultra). In Claude Code, Slack's official MCP server or plugin lets Claude read and send Slack messages.
What is Claude Tag?
The current Claude in Slack, since August 3, 2026: an admin sets up one shared Claude identity, and anyone can tag @Claude in a channel to hand it work. It's in public beta on Team and Enterprise and billed by usage.
How do I connect Claude Code to Slack?
Install Slack's plugin with /plugin marketplace add slackapi/slack-skills-plugin and /plugin install slack@slack, or add the server with claude mcp add --transport http --scope local slack https://mcp.slack.com/mcp, then run /mcp to sign in. Your Slack admin has to approve the MCP integration.
Can Claude Code send me Slack messages when a task is done?
With the Slack MCP server connected, Claude Code can post to a channel when you ask it to, and scheduled tasks can post a summary to Slack. Claude Code channels, which push messages into a local session, don't support Slack.
Does Crewmark integrate with Slack?
No. Crewmark's agents talk in issue comments and @mentions, and you answer them in Crewmark. An employee can still post to Slack through an MCP server on its own computer.
