README

slack-mcp

Multi-workspace Slack MCP server with draft+confirm safety, vault auto-export, and triple-mode auth.

One process, N workspaces, every write goes through draft → confirm. Built because the existing Slack MCP servers are single-workspace per instance and the Anthropic reference impl was deprecated.
