Open-Source Alternative: Self-Hosting Slack AI Agents with Channels SDK
allenaa3 · reddit · 2026-08-05
Anthropic's recently launched Claude Tag feature is highly anticipated but restricted to enterprise users. While seeking alternatives, a developer discovered the open-source Channels SDK, built on the Agent-User Interaction protocol.
The SDK allows users to bypass enterprise plans by self-hosting and connecting their own Claude API to achieve similar workflows in Slack. Key features include:
- Integration with MCP servers for existing tools
- Custom tools (like web search), approval gates, and multimodality
- Cross-platform memory and generative UI (e.g., rendering charts directly)
- Per-user automatic learning
The author also shares thoughts on safely deploying the SDK in team environments and discusses how much autonomy AI should be granted in shared channels.
