Heads-up: Slack currently only admits selected AI clients to its sign-in — we're working with the vendor on access. You can start free and connect it the moment it opens.

What you can do

What your AI can do with Slack

Real prompts you can type the moment it's connected — no setup, no docs to read.

“Summarize #support since yesterday.”

“Find the thread where we decided on the pricing change.”

“Post these release notes to #general.”

“What did I miss while I was out?”

Security check

How secure is the Slack MCP server?

Every server in the gate directory has to pass the same four checks before your AI can touch it. Here's how Slack holds up.

✓ Verified directory serverSlack · slack.com

Official endpoint

Operated by Slack (slack.com) at its documented MCP endpoint — not a third-party mirror or community re-host.

OAuth sign-in — your account, your rules

You grant access from your own Slack account and can revoke it there at any time. gate never sees your password.

Scanned before it goes live

gate checks every tool for prompt injection, hidden instructions, data-exfiltration hints, and over-broad permissions before the server is available through your gateway.

Watched for drift

If Slack adds or changes tools later, gate re-scans and alerts you — before your AI acts on the change.

Transparency: Slack's sign-in currently only accepts a fixed list of AI clients, so connecting through gate is pending the vendor's approval. The endpoint itself is verified and monitored.

How it works

Connected in three steps

FAQ

Questions, answered

Is there an official Slack MCP server?

Yes — Slack operates its own remote MCP server at mcp.slack.com. gate connects you to that official endpoint and adds security scanning, per-tool access rules, and an activity log on top.

How do I connect Slack to Claude or ChatGPT?

Add gate's gateway URL to your AI client once, then pick Slack in the directory. You sign in to Slack via OAuth to grant access. From then on, Slack's tools are available in every client you've connected to gate.

Do I need to host anything?

No. Slack runs the server, and gate is fully managed. You just connect one URL — there's nothing to install, deploy, or maintain.

Is the Slack MCP server safe to connect?

It's the vendor's official endpoint, and gate scans its tools for prompt injection and hidden instructions before it goes live, re-checks it whenever it changes, and lets you allow, block, or require approval for every single tool.
