About

Slack Bot MCP server that provides comprehensive Slack workspace integration with OAuth 2.0 authentication, JWT-based client identification, and PostgreSQL token storage for persistent multi-user access. Built with FastMCP and the official Slack SDK, the implementation offers 47+ tools covering messaging, channel management, file uploads, reactions, pins, bookmarks, user management, and team administration, with automatic file source detection for URLs, local paths, and text content. Features a complete OAuth callback flow that maps JWT client IDs to Slack workspace tokens, enabling secure multi-tenant usage where different users can authenticate with their own Slack workspaces, making it valuable for AI assistants that need full Slack functionality across multiple organizations without manual token management.
