Can I limit what agents can do in Slack?

Yes, twice over. The connection itself has an access level (Read-only, Read + send, Full access), and on top of that you can allow, scope, or deny each individual agent from the Integrations page.

Can I connect more than one Slack account?

Yes. Connect additional accounts from the same card and mark one as primary; agents use the primary unless a mission names a specific account.

How do I disconnect Slack?

Open Integrations, choose the account under Slack, and revoke it. Agents lose access immediately; nothing keeps working in the background.

Communication

💬 Slack integration

Access levels: Read-only · Read + send · Full access · Verified July 15, 2026

Connect Slack once and every agent in your squad can work in it for you, with exactly as much access as you decide to give, and a receipt for every call it makes.

What your squad can do in Slack

Look things up, admin conversations search; assistant search context; assistant search info, and more.
Do real work, add call participants; add emoji; add emoji alias; add enterprise user to workspace, and more.
Run it on a schedule: any of the 154 available tools below can be part of a scheduled task or a mission.

How to connect

In your dashboard, open Integrations and find Slack.
Click Connect and pick an access level (we recommend Full access): this is the ceiling for every agent.
Sign in to Slack in the window that opens and approve. You land back on the Integrations page with the account live.

You can change an account's access level any time under Manage. It applies instantly, no re-authorization. If the connection ever expires, the card shows Reconnect; one click re-authorizes the same account with the same settings.

Multiple accounts: connect as many as you need (say, yours and a client's). One is primary. Agents use it unless a mission says otherwise.

Access levels

The level you pick at connect time is enforced on our side for every agent call: an agent can never do more than the level allows, no matter what it's asked.

Level	What it allows
Read-only	Read messages in channels and DMs. Cannot send.
Read + send	Read history and post messages.
Full access	Read, post, manage channels, react, and pin.	Recommended

On top of the connection's level, every agent can be individually allowed, scoped down, or denied for this app from the Integrations page. Deny an agent and it doesn't even see the connection.

Every tool, in plain terms

The 154 tools agents use in Slack through Mission Control, and the lowest access level that includes each. Agents discover these themselves. You never have to name a tool; asking in plain language is enough.

What agents can't do in Slack (yet)

Anything not in the table above. The tools mirror what Slack makes available to connected apps. If Slack doesn't expose an operation, agents can't perform it either.
If something you need is missing, there's usually a path: add the service's API key under Settings → Custom integrations and your agents can call it directly. See custom integrations & secrets. You can also ask your lead agent to open a ticket describing what it needs.

Using it in missions

Just ask in plain language: “check Slack for …”, “create … in Slack”, “every Monday, … ”, and the agent finds the right tool, runs it, and reports back with a receipt in your Runs ledger. Anything outward-facing (sending, posting, publishing) that a mission didn't clearly authorize comes back to you as a ticket first.

Troubleshooting

Agent says	What's happening	Fix
"Slack isn't connected"	No active connection (or this agent is denied)	Connect on the Integrations page; check the agent's per-app policy
"The connection has expired"	Slack ended the authorization (they all do periodically)	Click Reconnect on the account, same settings, one click
"I'm not allowed to do that"	The action is above the account's access level, or the agent is scoped down	Raise the level under Manage, or adjust that agent's policy
It did something unexpected	The ask was ambiguous (e.g. matched an existing item)	Be explicit, "create a NEW …", and give agents a working folder where relevant
