Slack MCP Server

Full read + write access to Slack Lists for AI: create, update, check off, reassign, delete.

What the server does

This server acts as a bridge between AI models and Slack, enabling seamless creation, retrieval, updating, deletion, filtering, and management of Slack List items through a standardized protocol. It empowers AI assistants like Claude Desktop to become powerful productivity tools for managing tasks, projects, and data within Slack.

• Create Single Item — Add one item to a list with detailed fields
• Bulk Create Items — Add multiple items at once with built-in rate limiting to respect Slack's API
• Retrieve Items — Fetch a list of items with optional metadata
• Update Items — Update any cell on an existing item — check a task off, reassign it, reschedule it, or edit any field (full task management)
• Delete Items — Permanently remove an item from a list
• Discover Columns — Infer a list's column IDs, types, and select option IDs from its existing items (Slack exposes no schema API, so this saves you from hunting for IDs in browser dev tools)
