What is the Slack remote MCP server?
The Slack remote MCP server is a hosted Model Context Protocol endpoint at https://mcp.slack.com/mcp, so AI assistants can connect to it without installing or running anything locally.
How do I connect to the Slack MCP server?
Add the endpoint https://mcp.slack.com/mcp to any MCP-compatible client such as Claude Code, Cursor, or VS Code. The setup snippets on this page configure each client in one step.
Does the Slack MCP server require authentication?
Yes. Slack uses OAuth: the first time you connect, your MCP client opens a browser window to sign in and authorize access, then reuses the credentials for future sessions.

Slack exposes a Streamable HTTP endpoint, the transport used by remote MCP servers and supported by all major MCP clients.
