Slack Explorer MCP

Gives Claude direct access to your Slack workspace through a User Token, exposing six focused tools for message retrieval and search. You get search_messages with granular filters (channel, user, date range, reactions), get_thread_replies for conversation context, bulk user profile lookups, file search across canvases and attachments, and get_canvas_content for extracting HTML. Runs on stdio by default or as an HTTP server. Reach for this when you need Claude to dig through Slack history, analyze thread discussions, or pull context from past conversations without manually copying messages. Requires a User Token with appropriate scopes like channels:history, search:read, and files:read.
