assistant-ui React MCP

Always consult assistant-ui.com/llms.txt for the latest API.

@assistant-ui/react-mcp lets users connect preset or custom Streamable HTTP MCP servers in the browser. The manager persists server and auth state, exposes connection state to primitives, and registers each connected tool into modelContext as a frontend tool named serverId__toolName.

Mount the manager
