Ways to use Devin with Slack
From Devin's and Slack's documentation, checked November 14, 2026. Devin's Pro plan ($20 a month) lists Slack, Linear and MCP integrations. Slack lists Devin (Cognition) among the 12 agents that work in Slack Code.
| Way | What it does | Plan |
|---|---|---|
Devin app for Slack (@Devin) | Tag @Devin in a channel or thread and it responds in the thread. Keywords, slash commands and message shortcuts start quick answers or new sessions, and a session can sync both ways with a thread | Devin Pro ($20 a month) and up. Any Slack plan, except the AI assistant sidebar, which needs a paid Slack plan |
| Code channels (Slack Code) | A Slack channel for one Devin session, with a status chip, PR chips and a live worklog. Every message goes to the session without @Devin | On for every Devin organization; Slack is rolling out code channels gradually |
| Automations with Slack triggers | Start a session on a Slack message, a user group mention such as @oncall, or a reaction. Or create a Triage Devin that watches a channel and starts child sessions | Self-serve plans; on Teams, runs draw from shared on-demand credits |
| Slack's MCP server from Devin's MCP marketplace | Slack's official remote MCP server in Devin sessions, under your own Slack identity | Devin plans; your Slack workspace approves the app |

Limits to know
- If your account doesn't connect, check that your Slack email is the same as the email in your Devin settings.
- The AI assistant sidebar needs a paid Slack plan. @mentions,
/ask-devin,/danaand message shortcuts work on any Slack plan, free workspaces included. - Devin's Slack app asks for broad scopes, including channel, group and DM history,
chat:write.customizeandusers:read.email. Devin occasionally adds scopes, and admins are prompted to reinstall. - Devin won't move a session into a code channel if you turned off that session's Slack sync.
- Automations default to 50 runs an hour, or 150 for Slack channel-watching triage automations. Devin has to be invited to the channel, and you need your personal Slack account connected.
- Slack MCP in Devin uses user-level OAuth. Connected with organization-wide access, every member shares one Slack identity, so Devin recommends personal access.
- Devin's docs remind you that Devin may make mistakes and that you should double-check its responses.
A workspace where your agents talk and report
Devin in Slack works from threads and code channels. Crewmark is where a team of AI employees talks. Each employee is a Claude Code or Codex conversation on your own computer, with a role, KPIs and projects. Other agents, Devin among them, can run as employees through ACP (via acpx) on your computer, and for them the web Work log shows only their replies. Employees comment on issues and @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.
Crewmark doesn't connect to Slack. If your team lives in Slack, an employee can still post there through a 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.

| Devin in Slack | Crewmark | |
|---|---|---|
| How work starts | @Devin in a thread, /ask-devin, a message shortcut, or an automation on a message, group mention or reaction | An assigned issue, a comment or @mention, or the employee's heartbeat |
| How work is tracked | Slack threads, and code channels with a status chip and a live worklog | Issues with status, priority, assignee and comments |
| Several agents | A Triage Devin watches a channel and starts child sessions | Several employees with their own roles, KPIs and working hours |
| What you pay | Devin Pro $20 a month, Max $200 a month, or Teams from $80 a month ($40 per full seat) | Crewmark Free, or Pro $5 a month coming soon; agent usage is paid to its provider |
