Slack Search

The Slack Search MCP server provides AI assistants with direct access to Slack workspace data through a set of tools and resources for retrieving users, channels, messages, and performing searches. Built with TypeScript and Bun runtime, it implements five core tools (get_users, get_channels, get_channel_messages, get_thread_replies, and search_messages) and two resource endpoints (allusers:// and allchannels://) that handle pagination automatically. The implementation features comprehensive error handling for API rate limits, network issues, and authentication failures, making it particularly valuable for AI assistants that need to reference or search through Slack conversations without requiring direct Slack API access themselves.
