feat: use structuredContent with outputSchema in example servers (#220)
* build app-with-deps

* make registerAppTool more interchangeable w/ server.registerTool

* feat: use structuredContent in all example servers

All servers now return structuredContent alongside JSON text content.
All mcp-apps now read structuredContent directly (no JSON.parse fallback).

Updated servers:
- basic-server-vanillajs
- budget-allocator-server
- cohort-heatmap-server
- customer-segmentation-server
- integration-server
- scenario-modeler-server
- system-monitor-server
- threejs-server
- video-resource-server
- wiki-explorer-server

* feat: add outputSchema to all example servers

Define output schemas for structuredContent validation:
- basic-server-vanillajs: { time: string }
- budget-allocator-server: BudgetDataResponseSchema
- cohort-heatmap-server: CohortDataSchema
- customer-segmentation-server: customers/segments schema
- integration-server: { time: string }
- scenario-modeler-server: templates/defaultInputs schema
- system-monitor-server: SystemStatsSchema
- threejs-server: { code, height }
- video-resource-server: { videoUri, description }
- wiki-explorer-server: { page, links, error }

* prettier:fix

* prettier:fix

* revert: remove unrelated workflow, version, and arch changes

* chore: update package-lock.json

* refactor(basic-server-vanillajs): address PR review comments

- Simplify server.ts to return plain time string in text content (not JSON),
  matching the quickstart guide pattern
- Add defensive coding in mcp-app.ts with optional chaining and fallback
  to handle potential type mismatches gracefully

* refactor: restore rich text formatting for LLM-readable content

Restore the human-readable text formatting functions that were removed,
providing meaningful summaries in the text content while keeping
structuredContent for programmatic UI consumption:

- budget-allocator-server: formatBudgetSummary with config overview
- cohort-heatmap-server: formatCohortSummary with retention stats
- scenario-modeler-server: formatScenarioSummary with financial metrics

Example: Integration Test Server

An MCP App example used for E2E integration testing.

Overview

This example demonstrates all App SDK communication APIs and is used by the E2E test suite to verify host-app interactions:

Key Files

Getting Started

npm install
npm run dev

How It Works

  1. The server registers a get-time tool with metadata linking it to a UI HTML resource (ui://get-time/mcp-app.html).
  2. When the tool is invoked, the Host renders the UI from the resource.
  3. The UI uses the MCP App SDK API to communicate with the host and call server tools.
