What is CopilotKit Channels SDK?
CopilotKit Channels SDK is an open-source, self-hostable framework that connects any AG-UI-compatible AI agent to Slack, Microsoft Teams, Discord, and other communication platforms. Instead of forcing agents into a custom chat widget, Channels lets your existing agent—with its tools, model, and business logic intact—operate natively inside the channels where your team already works. The SDK handles the platform-specific rendering, conversation context, and interaction layer, so your agent can stream responses, call tools, work with files, and pause for human approval without you rebuilding anything.
Who it's for
- Developer teams building production agents — if you've already invested in an agent framework like LangGraph, CrewAI, Mastra, Pydantic AI, or Google ADK, Channels plugs your existing work into Slack and Teams without a rewrite.
- Platform engineers tired of maintaining integrations — the SDK abstracts away Slack Block Kit and Teams Adaptive Cards, so you describe a message once and it renders natively everywhere.
- Teams that need human oversight in automated workflows — if your agents act on sensitive actions, Channels puts approval gates, buttons, and choices directly into the conversation before anything executes.
Key features
Bring your own agent
Channels works with CopilotKit's built-in agent or any AG-UI-compatible framework—LangGraph, CrewAI, Mastra, Pydantic AI, Google ADK, and more. Your agent keeps its existing tools, model, and business logic; Channels only adds the communication layer.
Native UI rendering
Describe a message once, and Channels renders it as Slack Block Kit, Teams Adaptive Cards, or platform-specific UI automatically. No more writing and maintaining separate UI code for each channel your agent lives in.
Human-in-the-loop approvals
Put buttons, choices, and approval gates directly into the conversation. The agent can pause mid-task, ask a person to confirm, and only proceed once approved—keeping people in control of high-stakes actions.
Single-prompt setup
Run npx copilotkit@latest channels setup, and the CLI installs a setup skill, prints a prompt, and copies it to your clipboard. Paste it into your coding agent, and it walks through the entire configuration—project, agent, managed channel, provider app, and runtime—using a live guide that stays current.
What stands out
Your agent keeps its tools, model, and business logic—Channels gives it a native place to work with people.
Most agent-to-channel solutions force you to adapt your agent to a platform's constraints or rebuild your UI for each destination. Channels flips that: the agent stays exactly as you built it, and the SDK handles the platform-specific translation. The managed connection through CopilotKit Intelligence means you don't run your own Slack or Teams app infrastructure, while your agent logic still runs entirely in your own environment. And because the setup guide is fetched live during installation, the workflow never goes stale—even if you installed the skill months ago.
Worth checking out if…
You're building an agent that needs to meet users where they already work—whether that's Slack, Teams, or Discord—and you don't want to maintain separate integrations for each. It's especially valuable if you're already using a modern agent framework and want human approval workflows, interactive UI, and per-user context without rebuilding your agent from scratch. If you prefer full control, the self-hostable, open-source nature means you can run everything on your own infrastructure.
