Show HN: slack-explorer-mcp – Let AI find historical context in Slack

2 shibayu36 0 9/2/2025, 11:14:31 PM github.com ↗

I built an MCP server that lets AI tools search Slack history to answer “why did we do X?” It reads messages and threads with your Slack user token, so agents like Claude Code/Desktop, VS Code and Cursor can pull context that isn’t in code or PRs.

Features: * Search by channel, user, date range, reactions, has:file, etc. * Get full thread replies. * Look up users by ID or display name.

Example uses: * “Why is foo_summary BigQuery table a materialized view?” * “Summarize this week’s topics in #random.”

More details in the blog post: https://dev.to/shibayu36/making-historical-context-easily-di...
