Use the Slack MCP server
in Claude Code

Search messages, post to channels, and read your Slack workspace from your AI. This guide connects Slack to Claude Code (the terminal agent) through a governed gateway — one URL that also works in every other MCP client you use, with your rules and a full log attached.

Setup: Slack in Claude Code

Claude Code adds MCP servers via the `claude mcp add` command. The gateway route takes about two minutes:

  1. Connect Slack to your free gate gateway from the verified directory.
  2. In your terminal: claude mcp add gate https://gateturbo.com/api/mcp --transport http
  3. Approve the sign-in when Claude Code opens it in your browser.
  4. Slack's tools now appear in every Claude Code session — with per-tool allow/ask/block rules if you want them.

What to ask once it’s connected

“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?”

Why route it through a gateway

One URL, every client

The same Slack connection works in Claude, ChatGPT, Cursor, VS Code too — no per-client re-wiring.

Rules before regret

Allow, ask, or block every tool Slack exposes — reads can flow freely while writes require your approval.

Every call logged

A plain-language activity log of everything Claude Code did with Slack — searchable, exportable, auditable.

Scanned and probed

Slack passed a live handshake probe and a security scan before listing — and drift detection watches it after you connect.
