Overview

Slack is a Model Context Protocol server that lets you read and write Slack messages and content using session tokens, without needing OAuth, a bot account, or admin approval. It exposes Slack functionality as tools that AI assistants can invoke directly on your behalf.

The server runs locally on your machine. Install it with npx -y @aaronsb/slack-mcp. It communicates with MCP clients over stdio and requires a Slack API key for authentication. Version v2.2.2 is published under the MIT license, with source code available at aaronsb/slack-mcp on GitHub.

Slack belongs in the Communication category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain this server, claim this listing to verify ownership and keep information up to date.
