- Python qr-server uses uv with local path
- Removed Claude Desktop-specific references from qr-server
* feat(shadertoy): add fullscreen support
Add fullscreen toggle button that appears when the host supports fullscreen
display mode. Uses the same pattern as pdf-server:
- Check availableDisplayModes in host context
- Show/hide button based on capability
- Toggle between inline and fullscreen via requestDisplayMode()
- Update UI state on host context changes

* fix(examples): resolve DIST_DIR path for npm package execution
When servers are compiled to dist/server.js and published to npm,
`import.meta.dirname` already points to dist/, so joining with "dist"
results in dist/dist/ which doesn't exist.
This fix detects whether we're running from TypeScript source or
compiled JavaScript and adjusts the path accordingly:
- From source (server.ts): use dist/ subdirectory
- From compiled (dist/server.js): use current directory
Fixes ENOENT errors like:
"ENOENT: no such file or directory, open '.../dist/dist/mcp-app.html'"

* fix(pdf-server): mark pdfjs-dist as external in bundle
The pdf.worker.mjs file wasn't being found when running from npm
because bun bundled pdfjs-dist but didn't include the worker file.
By marking pdfjs-dist as external, it uses the installed package
from node_modules at runtime where the worker is available.

* map-server: fix async/await in ontoolresult, remove unused getViewStorageKey
* pdf-server: fix scrolling gap in inline mode
- Set html/body background to match .main background color
This hides any gap between .main and iframe border
- Change .main from height:100% to min-height:100%
Ensures .main fills container properly
* feat: compile example servers to JavaScript for npm consumption
Add TypeScript compilation for server code so the example packages can be
imported and used by consumers without requiring TypeScript compilation.
Changes:
- Add tsconfig.server.json to each example for compiling server code
- Update package.json exports to point to compiled dist/server/server.js
- Add types field pointing to dist/server/server.d.ts
- Update build scripts to include server compilation step
- Fix .ts import extensions to .js in customer-segmentation-server
This enables importing the createServer function from published packages:
import { createServer } from '@modelcontextprotocol/server-basic-react';
* fix: add type assertion for Nominatim API response
* chore: regenerate schemas
* refactor: split server examples into library and binary entry points
- server.ts: exports createServer() only (library entry point)
- main.ts: entry point with main() that runs the server (binary)
- package.json: adds bin field for npx support, uses inline bun build
- tsconfig.server.json: emitDeclarationOnly, outputs to dist/
This allows:
1. Importing the server as a library: import { createServer } from '@modelcontextprotocol/server-basic-react'
2. Running with npx: npx @modelcontextprotocol/server-basic-react [--stdio]
Added migration script at scripts/migrate-server-examples.ts
* refactor: migrate remaining server examples to library/binary structure
Apply the same refactoring to all 13 remaining server examples:
- scenario-modeler-server, shadertoy-server, map-server
- cohort-heatmap-server, customer-segmentation-server, video-resource-server
- system-monitor-server, budget-allocator-server, sheet-music-server
- threejs-server, integration-server, transcript-server, wiki-explorer-server
Each now has:
- server.ts: exports createServer() (library)
- main.ts: runs the server (binary with shebang)
- bin field in package.json for npx support
* chore: remove unused server-utils.ts from video-resource-server/src
* update
* fix(build): make Windows-compatible by removing chmod and fixing bun externals
- Remove 'chmod +x dist/index.js' which doesn't exist on Windows
- Add '--external ./server.js' to prevent bun from treating the import as a second entry point
* fix(build): use .ts import for bun compatibility
- Change import from './server.js' to './server.ts' in main.ts files
- Remove --external flag since bun should inline everything
- Fixes Windows build where bun couldn't resolve .js to .ts properly
* fix(build): use --external for Windows bun compatibility
Bun on Windows incorrectly treats imported .ts files as entry points.
Use --external './server.js' to work around this, creating a runtime
dependency between index.js and server.js.
* style: fix prettier formatting in pdf-server/main.ts
* fix(build): remove quotes from --external for Windows cmd.exe compatibility
* fix(build): use glob pattern for --external to work on all platforms
The literal path --external ./server.js was not matching the import.
Using glob pattern --external "./server*" correctly externalizes the server module.
* fix(build): use */server.js pattern for --external
The "./server*" pattern was not matching on Windows.
Using "*/server.js" matches any path ending in /server.js which works cross-platform.
* fix(build): use *server.js pattern without slash for Windows compatibility
* update package-lock
* chore: regenerate package-lock.json for cross-platform compatibility
* fix(build): use ./server.js instead of glob pattern for Windows compatibility
* fix(build): use double quotes for banner to fix Windows cmd.exe compatibility

* fix(map-server): improve updateModelContext and fix initialization
- Use structured YAML frontmatter format for model context (like pdf-server)
- Add tool name, altitude, and cleaner data format
- Fix initialization deadlock: app.connect() was inside ontoolresult handler
which could never fire until connected
- Fix view state persistence: widgetUUID now properly extracted from
ontoolresult and used to restore persisted camera position
- Server now includes widgetUUID in tool result _meta for widget identification
* fix(pdf-server): use widgetUUID for page persistence
- Add widgetUUID to tool result _meta for widget identification
- Use widgetUUID instead of generated key (pdfUrl+toolId) for localStorage
- Enables reliable page restoration when revisiting PDF widgets
* fix(transcript-server): use structured YAML frontmatter for model context

- Replace requirements.txt with inline script dependencies in server.py
- Add package.json with npm scripts for run-all.ts integration
- Update CI workflow to install uv via astral-sh/setup-uv@v5
- Update Docker commands to install uv for e2e tests
- Add Playwright golden screenshot for qr-server
- Update README with uv installation and usage instructions
* feat(pdf-server): Interactive PDF viewer example
PDF viewer with PDF.js featuring:
- Chunked binary loading with progress bar
- Text extraction for AI context
- arXiv paper support (fetch by ID)
- Page navigation with keyboard shortcuts
- Zoom controls (including Ctrl+0 reset)
- Fullscreen mode support
- Horizontal swipe for page changes (disabled when zoomed)
- Page persistence in localStorage
- Text selection via PDF.js TextLayer
- Clickable title link to source URL
- Rounded corners and subtle border styling
* chore: Add pdf-server to screenshot generation list
* refactor(pdf-server): Simplify and generalize PDF loading
- Accept any HTTP(s) URLs instead of ArXiv-only
- Use HTTP Range requests for chunked binary loading
- Remove ArXiv-specific code (arxiv.ts, metadata fetching)
- Remove CLAUDE.md index generation
- Flatten hierarchical folder structure to simple entries list
- Remove dead code: getPdfSummary, httpFileSizes
- Simplify base64 encoding using Buffer
- Simplify chunk extraction using slice()
- Consolidate DEFAULT_PDF_URL constant
The server now works with any PDF URL, not just arXiv papers.
HTTP Range requests stream chunks on-demand when supported.
* feat(pdf-server): Include title and selection in model context
- Add pdfTitle to updateModelContext structuredContent
- Include selection position (text, start, end) when text is selected
- Add debounced selectionchange listener to update context on selection
* fix(pdf-server): Restore default URL in view_pdf schema
The UI needs the default value in the schema to show it properly.
* refactor(pdf-server): Further simplifications
- Remove hard-coded test paths from main()
- Remove unused resources: pdfs://metadata/{pdfId}, pdfs://content/{pdfId}
- Remove unused metadata fields: subject, creator, producer, creationDate, modDate
- Remove unused entry fields: relativePath, estimatedTextSize
- Remove filterEntriesByFolder and folder filter from list_pdfs
- Remove redundant output schema validation (trust typed returns)
- Simplify scanDirectory and createLocalEntry signatures
Total: 1836 → 1666 lines (-170 lines, -9%)
* refactor(pdf-server): Major simplification for didactic focus
Simplified the example to focus on key MCP Apps SDK patterns:
- Chunked data through size-limited tool calls
- Model context updates (page text + selection)
- Display modes (fullscreen vs inline)
- External links (openLink)
Changes:
- Remove local file support (HTTP URLs only)
- Restrict dynamic URLs to arxiv.org for security
- Simplify types: url instead of sourcePath/sourceType
- Simplify indexer: 168 → 44 lines
- Simplify loader: 318 → 171 lines
- Simplify server: 337 → 233 lines
- Fix selection text normalization
- Rewrite README with didactic focus
Total: 1836 → 1236 lines (-33%)
* feat(pdf-server): Add file:// URL support for local files
- Local paths are converted to file:// URLs on startup
- file:// URLs must be in the initial list (strict validation)
- Dynamic URLs still restricted to arxiv.org only
- Updated README with local file examples
* fix(pdf-server): Improve selection detection with logging
- Add logging to selectionchange handler to verify it fires
- Add fallback matching without spaces (TextLayer spans may lack spaces)
- Log selection detection success/failure for debugging
The issue: PDF.js TextLayer renders text as positioned spans without
space characters between them. When selecting across spans:
- pageText has spaces (items joined with ' ')
- sel.toString() may not have spaces
- indexOf fails to match
The fix tries exact match first, then falls back to spaceless matching.
* feat(pdf-server): Format model context as markdown with front matter
Model context now looks like:
```markdown
---
url: https://arxiv.org/pdf/...
page: 5/144
---
Page text with <pdf-selection>selected text</pdf-selection> inline.
```
This is cleaner for the model to parse and includes the source URL.
* refactor(pdf-server): Extract smart truncation helpers
Added two well-designed helpers:
formatPageContent(text, maxLength, selection?)
- Centers truncation window around selection if present
- Adds <truncated-content/> markers at elision points
- Wraps selection in <pdf-selection> tags
- Allocates 60% context before, 40% after for readability
findSelectionInText(pageText, selectedText)
- Tries exact match first
- Falls back to spaceless match for TextLayer quirks
- Returns { start, end } or undefined
Example output with selection:
```
<truncated-content/>
...context before... <pdf-selection>selected text</pdf-selection> ...context after...
<truncated-content/>
```
* fix(pdf-server): Truncate inside selection tags when selection too long
When selection is too large for the budget:
<truncated-content/><pdf-selection><truncated-content/>start...end<truncated-content/></pdf-selection><truncated-content/>
This keeps the selection structure intact while showing beginning and end.
* refactor(pdf-server): Remove unused read_pdf_text, use Attention paper as default
- Remove read_pdf_text tool (viewer extracts text client-side with pdfjs)
- Remove PdfTextChunk and ReadPdfTextInput types
- Remove loadPdfTextChunk from pdf-loader
- Change default PDF to 'Attention Is All You Need' (1706.03762)
- Update README with modest language
* refactor(pdf-server): Simplify to use URL as ID, rename view_pdf to display_pdf
Major simplifications:
- Use URL directly as identifier (no hashing)
- Remove displayName - show elided URL with full URL as tooltip
- Rename view_pdf to display_pdf with better description
- Update all references from pdfId to url
- Simplify storage key and model context
The tool description now explains it displays an interactive viewer in the chat.
* feat(pdf-server): Normalize arxiv URLs to PDF format
arxiv.org/abs/... -> arxiv.org/pdf/...
Applied both at startup and when loading dynamic URLs.
* docs(pdf-server): Add prompt engineering to display_pdf description
* fix(pdf-server): Sharp rendering on retina displays
Account for devicePixelRatio when rendering canvas:
- Scale canvas dimensions by dpr
- Scale context by dpr
- Keep CSS size at logical pixels

(which adds the entry) and read_pdf_bytes (which previously only looked
up existing entries). Now read_pdf_bytes mirrors display_pdf's logic
and dynamically adds arxiv URLs to the index.

- Wait 5 seconds for full app load (tiles, animations, data)
- Screenshot just the inner iframe (no extra whitespace)
- Save both screenshot.png (full-size) and grid-cell.png (300x300 thumbnail)
- Use contain mode to preserve aspect ratio
* fix: use cover mode with top alignment for grid thumbnails
No letterboxing - crops to fill 300x300, aligned to top so headers
and important content are always visible.
* feat: improve screenshot gallery
- Remove integration-server from gallery (it's for E2E testing only)
- Add 30s extra wait for Map and Video servers to load fully

* feat(map): add keyboard shortcuts for fullscreen control
- Escape: exit fullscreen when in fullscreen mode
- Ctrl/Cmd+Enter: toggle fullscreen from any mode
* feat(map): persist view state to localStorage
- Save camera position/orientation on moveEnd (debounced 500ms)
- Restore persisted view when no explicit tool input is received
- Key by toolInfo.id (tool invocation ID) - localStorage is per-conversation
- Tool input (explicit bbox) takes precedence over persisted state
* refactor(map): use app.updateModelContext() instead of adhoc request

* refactor(basic-host): use SDK types for ModelContext and AppMessage
- Import McpUiUpdateModelContextRequest and McpUiMessageRequest from SDK
- Replace custom ModelContext with McpUiUpdateModelContextRequest['params']
- Replace custom AppMessage with McpUiMessageRequest['params']
- Pass full message params instead of extracting text
- Format messages by extracting text from content blocks in display
* feat(basic-host): handle non-text content blocks in display
- Add formatContentBlock helper for text, image, audio, resource types
- Show placeholders like <image: image/png> for non-text content
- Apply to both messages and model context display
* test: update shadertoy screenshot
* test: update screenshots from CI (linux x64)
Update all example servers to use the new recommended metadata format
for associating UI resources with tools. The old `RESOURCE_URI_META_KEY`
constant is deprecated in favor of the nested `_meta.ui.resourceUri`
structure.
