Claude Threads

Claude Code × Slack & Mattermost

  claude-threads.run

Run Claude Code from your team's chat. The bot lives on your machine, next to your checkout and your local tools. Sessions stream live into Slack or Mattermost threads where teammates watch and steer what Claude does. No cloud sandbox and no enterprise plan required: it works with the Claude subscription or API key you already have.
_Think of it as screen-sharing for AI pair programming, but everyone can type._

    Mattermost

How it works

1. Mention the bot in a channel: @claude fix the flaky test in ci.yml
2. It spawns a real Claude Code session in a working directory on your machine.
3. Everything streams into the thread: output, diffs, task lists, permission prompts.
4. Steer by replying in the thread or reacting with emoji. Anyone you invite can do the same.

Features

- Live streaming - Responses, tool calls, diffs, and a sticky task list render in the thread as the session runs
- Slack and Mattermost - Connect multiple workspaces at once. Mattermost support means this also works where chat is self-hosted and cloud assistants cannot go
- A session per thread - Concurrent sessions, each with its own working directory, resumed automatically after a bot restart
- Your machine, your setup - Sessions use your local checkout plus whatever MCP servers and plugins you already configured
- Your existing subscription - Any Claude Pro/Max account or API key works. An optional multi-account pool routes each new session to the account with the most subscription headroom and cools down rate-limited ones (docs)
- Permission control by emoji - default prompts the thread for every tool use (👍/✅/👎), auto lets Claude's classifier approve low-risk actions, bypass skips prompts entirely. Switch…
