CopilotKit Integrations

Live Documentation (MCP)

This plugin includes an MCP server (copilotkit-docs) that provides search-docs and search-code tools for querying live CopilotKit documentation and source code. Useful for looking up framework-specific integration details.

• Claude Code: Auto-configured by the plugin's .mcp.json -- no setup needed.
• Codex: Requires manual configuration. See the copilotkit-debug skill for setup instructions.

Overview

CopilotKit connects to external agent frameworks through the AG-UI (Agent-UI) protocol -- a streaming protocol that enables bidirectional communication between a frontend CopilotKit application and a backend agent. Every integration follows the same architectural pattern:

1. Agent server -- your agent framework runs as an HTTP server (usually FastAPI/uvicorn for Python, or an Express/Next.js route for JS/TS)
2. AG-UI adapter -- a framework-specific adapter translates between the agent's native interface and the AG-UI wire protocol
3. CopilotKit runtime -- the Next.js catch-all API route creates a CopilotRuntime that connects to the agent via an AG-U…
