8550545ccbAccording to spec, mimeType should be present in both the resource declaration and the resource content. This adds the missing mimeType to the registerResource() declaration (third parameter) in all example servers and the quickstart documentation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-authored-by: Claude <noreply@anthropic.com> Co-authored-by: ochafik <olivier.chafik@gmail.com> |

basic-server-vanillajs!
Overview
- Tool registration with a linked UI resource
- React UI using the
useApp()hook - App communication APIs:
callServerTool,sendMessage,sendLog,sendOpenLink
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.
