Productivity · Slack (Salesforce)

Set up Slack

Slack's own hosted server: search messages, read channels and threads, and post as the signed-in user.

Publisher: Slack (Salesforce) Official
Hosted endpoint: https://mcp.slack.com/mcp
Transports: streamable-http
Authentication: OAuth through a registered Slack app, without dynamic registration. Partner clients include Claude Code and Cursor.
What it can touch: Reads your messages and posts on your behalf.
Status: Active

Install

The vendor hosts this server, so you only add its URL and nothing runs on your machine. If it needs authentication, the row above says how; OAuth servers prompt you on first connection.
