Example: Basic Server (React)
An MCP App example with a React UI.
Tip
Looking for a vanilla JavaScript example? See
basic-server-vanillajs!
Overview
- Tool registration with a linked UI resource
- React UI using the
useApp()hook - App communication APIs:
callServerTool,sendMessage,sendLog,openLink
Key Files
server.ts- MCP server with tool and resource registrationmcp-app.html/src/mcp-app.tsx- React UI usinguseApp()hook
Getting Started
npm install
npm run dev
How It Works
- The server registers a
get-timetool with metadata linking it to a UI HTML resource (ui://get-time/mcp-app.html). - When the tool is invoked, the Host renders the UI from the resource.
- The UI uses the MCP App SDK API to communicate with the host and call server tools.
