You are responsible for ensuring your use complies with your organisation’s policies and Slack’s terms of service.

Description

Typical use scenarios:

• archive your private conversations from Slack when the administrator does not allow you to install applications OR you don't want to use potentially privacy-violating third-party tools;
• archive channels from Slack when you're on a free "no archive" subscription; so you don't lose valuable knowledge in those channels;
• create a Slack Export archive without admin access;
• create incremental Slack archives, which is particularly useful for free workspaces with 90-day limits;
• save your favourite emojis; AND
• analyse you Slack data with AI Agent using Slackdump MCP Server.

There are several modes of operation

1. List users/channels
2. Dumping messages and threads
3. Creating a Slack Export in Mattermost or Standard modes.
4. Creating an Archive (Sqlite database or stored as json+gz)
5. Converting an archive to other formats (Export, Dump).
6. Emoji download mode.
7. Viewing Slack export, dump or archive files or directories (displays images).
8. Search mode (messages and files).
9. Resuming previous archive (adding new messages to an existing archive).
10. Local MCP Server to use with Opencode, Claude, or any other AI tool supporting mcp over STDIO or HTTP.
