rusq/slackdump

Supports multiple archive formats (SQLite, JSON+gzip) and export modes (Standard, Mattermost) for cross-platform compatibility, plus incremental backup capabilities for workspaces with message retention limits. Built in Go with a CLI-driven architecture offering diverse operational modes—from message dumping to emoji archival to filesystem-based search—alongside a Model Context Protocol (MCP) server for AI agent integration via stdio/HTTP transports. Integrates with Discord migration tools (Slackord2), third-party export viewers, and AI assistants like Claude and OpenCode through standardized MCP protocol support.
