Show HN: The Channels SDK – Bring Any Agent to Any Channel (Slack, MS Teams)
The Channels SDK lets engineers embed AI agents directly into Slack, Microsoft Teams, and other chat platforms with native UI components.
Teams that already use Slack or Teams for daily work no longer have to switch to a separate web app to interact with an AI agent. The SDK handles the platform-specific UI rendering, so the same agent code can run across multiple chat surfaces without duplication. Adoption cost is a long-running Node process and platform credentials, but the agent’s core logic stays in your infrastructure.

Agents keep their existing tools and model; Channels only adds the chat-platform UI layer.
Native UI elements (Slack Block Kit, Teams Adaptive Cards) are generated from a single description.
Setup requires Node.js 22+, a persistent process, and platform credentials; credentials never leave your environment.
THE READ
What the cluster adds up to.
The Channels SDK shifts the integration boundary from a web dashboard to the chat platforms where engineers already collaborate. Instead of building a separate frontend for each agent, teams describe the interaction once and let the SDK render platform-native UI. This reduces frontend duplication but adds a dependency on CopilotKit’s runtime and Intelligence service for connection management.
Adoption requires a long-running Node process and platform credentials for Slack or Teams. The agent’s business logic remains in your infrastructure, but the SDK manages the connection and UI rendering. Credentials are never passed to the CLI, so they stay in your .env file. If the agent needs to call external tools, those calls still originate from your infrastructure, not the chat platform.
The SDK supports any AG-UI-compatible agent, so teams can reuse existing agents without rewriting them. However, the UI description must be written in a way that the SDK can translate to Slack Block Kit or Teams Adaptive Cards. If the agent’s UI needs exceed what those frameworks support, the SDK’s rendering layer becomes a constraint.
Setup can be driven by a coding agent following a hosted guide or by running CLI commands manually. The hosted guide is kept current, but it requires the agent to have browser or computer-use tools. Manual setup gives more control but requires familiarity with the CLI and platform-specific app creation. Both paths end with the same runtime and connection requirements.
