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 }

- wiki-explorer-server: { page, links, error }
* 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

Use content instead of structuredContent in examples
...
Not all MCP clients support structuredContent in MCP tool results, so
examples now return data as JSON in content and parse it client-side.
Pattern used:
- Server: content: [{ type: "text", text: JSON.stringify(data) }]
- Client: JSON.parse(result.content!.filter(...).map(...).join(""))
