How do I connect Slack to Claude?
Slack over MCP gives Claude channel history, thread replies and cross-workspace search — the org's conversation, retrievable at last.
Direct answer: connect Slack's MCP surface in Claude — Settings → Connectors, authorise the workspace ('claude mcp add' in Claude Code). Claude then reads channel history, thread replies, channel lists and cross-workspace search. What was said, by whom, in which thread, across every channel you can see — answered without the infinite scroll.
Retrieval beyond any scroll
What did engineering conclude about the migration, where is the thread where the client changed the deadline, who flagged the invoice issue first — searched and read in conversation. Slack is the org's memory of what was said; connected, it stops being write-only.
Said is not settled
Here is the distinction this connector makes urgent: threads are full of sentences that sound like decisions. 'Let's go with option B' at 11pm, three replies deep, half the room absent. A workspace search retrieves the sentence; whether option B was ever actually ratified — and what reasoning it stood on — is a different kind of fact, and the transcript alone leaves it unconfirmed.
Threads read against the record of what stands
Through Unl a Slack read arrives with the authority layer present: the thread proposes option B — which matches, or contradicts, the call you actually ratified, with its reasoning served alongside. Conversation gets demoted to evidence; your settled record holds authority. That ordering is the whole difference between a searchable chat log and a governed one.
Slack to Claude retrieves what was said; Slack through Unl reads what was said against what you actually settled — so a late-night thread stops passing for a ratified call.
Reads through Unl arrive with measured context — in the presence of the decisions you’ve already settled. The reach lane is live: one box, paste anything. If it speaks MCP, Unl can reach it. Readings arrive unprompted, the data beside the criterion; Unl is a courier, not a warehouse, and keeps only your keys and the frame.

Questions people ask
What does the Slack MCP surface expose?
Channel history, thread replies, channel lists and cross-workspace search — the retrieval layer over everything the authorising user can see.
Can other MCP clients connect to Slack the same way?
Yes; the surface is protocol-standard. ChatGPT and other clients add it through their own connector settings.
How does a decision get from Slack into Unl?
By your gesture: when something genuinely settles, you keep it — with its why. Nothing scrapes the workspace, and no message can write silently. That boundary is what makes the settled record trustworthy against the rest of the thread.
What this is
Think inside your AI world — you stay in command
Unlimitless (Unl to friends) holds what you've settled, reads what your tools are showing, and catches what's changed out in the world — and hands your AI whatever bears on the work, the moment it's needed, without you asking. The right thing, in front of the model, unprompted, with you in command of the call. So you keep moving toward what you set out to build, on top of everything you've already decided.
It plugs into Claude, Claude Code, ChatGPT and Cursor as an MCP connector. Quick to connect, in a couple of steps.
Unlimitless is open now to invited Alpha. Apply for the Beta waitlist to come in ahead of the full launch:
