Slack Conversations

Summary

Slack MCP Server provides a bridge between AI assistants and Slack's messaging platform, enabling access to conversation history from Slack channels. Developed by Dmitrii Korotovskii, this Go implementation authenticates with Slack using XOXC and XOXD tokens, handling the necessary HTTP transport customization to maintain session cookies. The server supports both stdio and SSE transport modes, includes API key authentication for secure access, and offers optional HTTP proxy and custom CA certificate configuration. Particularly useful for AI assistants that need to analyze, reference, or work with team communications stored in Slack channels without requiring direct Slack API integration.
