react-mcp
Lets end users add, authenticate, and manage MCP servers from the browser in assistant-ui apps with @assistant-ui/react-mcp. Use when building user-managed MCP server UIs: mounting McpManagerResource via useAui({ mcp }), declaring presets with defineConnector, dropping in McpConfigDialog, or composing McpManagerPrimitive (Root, Connectors, CustomServers, AddCustomTrigger), McpServerPrimitive (Root, Name, Icon, Status, ConnectButton, DisconnectButton, OAuthLink, RemoveButton, Error, Tools, ToolName), McpAddFormPrimitive (NameField, UrlField, AuthSelect, AuthFields, Submit, Cancel), and McpElicitationPrimitive (Root, Message, Fields, Items, Accept, Decline, Cancel, Error) for server-initiated input requests. Covers auth modes none/bearer/oauth, the OAuth flow with McpOAuthCallback and useMcpOAuthCallback, connection states, storage via McpLocalStorage/McpMemoryStorage/McpCustomStorage, reading state with useAuiState (s.mcp, s.mcpServer) and useMcpElicitation/useMcpElicitationField/useMcpServerTool, and imperative addCustomServer/connect/callTool. Distinct from developer-defined backend @ai-sdk/mcp tools in the tools skill. Reach for this when connected-server tools are missing, OAuth never completes, an elicitation prompt does not render, or servers do not persist.
