Slack MCP Server

jtalk22/slack-mcp-server

Gives your AI assistant direct Slack access using browser session tokens instead of OAuth, sidestepping app registration and admin approval entirely. Exposes 21 tools including conversation history, search, thread retrieval, message sending, reactions, and mark-as-read. Newer workflow primitives let you save profiles that bind channels to structured output formats like incident summaries or support triage queues, with a hosted brain service that returns parseable JSON for downstream automation. Works with Claude Desktop, Cursor, Windsurf, and Gemini CLI out of the box. The session token approach means no bot user appears in workspace admin panels. Setup takes two minutes via npx, and the token refresh tool pulls fresh credentials directly from Chrome's local database.
