Slack Explorer MCP

What it does

Slack Explorer connects an AI agent to a Slack workspace, enabling sophisticated retrieval of conversations, file metadata, and user information. It is designed for users who need to synthesize information across multiple channels or deep-dive into specific message threads using a User Token (xoxp).

Tools

• search_messages: Perform advanced searches with filters for channels, users, date ranges, and reactions.
• get_thread_replies: Retrieve all replies within a specific message thread with pagination support.
• get_user_profiles: Bulk retrieve profile data (names, emails) for a list of user IDs.
• search_users_by_name: Find users by display name with exact or partial matching.
• search_files: Search for canvases, PDFs, and images across the workspace.
• get_canvas_content: Extract HTML content from Slack canvases.
