Slack

Slack MCP Server is a TypeScript implementation that enables AI assistants to interact with Slack workspaces through a standardized interface. Developed by Ubie, Inc., it provides nine tools for common Slack operations including listing channels, posting messages, retrieving user profiles, searching messages, and managing reactions. The server validates requests using Zod schemas, calls the appropriate Slack Web API endpoints, and returns parsed responses with only necessary fields. It requires both Slack Bot and User OAuth tokens for authentication and can be run as a standalone server or integrated into existing applications.
