Rename `startServer` to `startStreamableHTTPServer` and add a new
`startStdioServer` helper to make the transport type explicit. Remove
the `ServerOptions` interface in favor of reading `PORT` directly from
the environment inside the function (defaulting to `3001`).
Also update Python examples to default to port `3001` for consistency.

* docs: standardize UI terminology to use "view" consistently
Replaces "widget" and "Guest UI" terminology with "view" across
the codebase as decided in the community survey.
This change updates:
- Specification document
- SDK source code and JSDoc comments
- Example servers and documentation
- Plugin documentation and skills
Closes#71
Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
Add `App_onhostcontextchanged_respondToDisplayMode` example showing how to
listen for display mode changes and update UI with `classList.toggle()`.
Update `App_requestDisplayMode_fullscreen` to `App_requestDisplayMode_toggle`
to show the common toggle pattern checking `availableDisplayModes` first.
Refactor full examples (pdf-server, shadertoy-server) to use
`classList.toggle(class, condition)` instead of add/remove branches.

* feat(shadertoy): add proper mouse/touch interaction support
- Fix iMouse uniform to match official Shadertoy specification:
- iMouse.xy only updates while button/touch is held down
- iMouse.zw uses positive values when down, negative when released
- Enables proper click detection via iMouse.z > 0
- Add touch event support for mobile devices:
- touchstart/touchmove/touchend/touchcancel handlers
- Same behavior as mouse events
- Update tool description with mouse interaction documentation
- Update README with:
- Mouse & Touch Interaction feature
- Improved Julia Set example with click detection
- iMouse specification table and usage examples
The iMouse uniform is a core Shadertoy feature used by popular shaders
like Star Nest, raymarching examples, and particle systems.
* style: fix Prettier formatting in shadertoy README
Shadertoy server improvements:
- Add ontoolinputpartial handler to show code preview during generation
- Add IntersectionObserver to pause/play shader based on visibility
- Apply host style variables (theme, colors, fonts)
- Add border-radius with fullscreen mode support
- Use gradient background and ghost text color for code preview
Skill documentation updates:
- Add streaming partial input section with use cases
- Add visibility-based resource management pattern
- Add fullscreen mode API and CSS patterns
- Expand host styling with CSS variable usage examples
Add stdio transport configuration snippets near the top of each example
README to help users quickly set up the servers in their MCP clients.
- Node.js examples use npx with the published npm packages
- 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.

* 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

* feat: add script to generate 300x300 grid-cell.png screenshots for examples
- Add generate-grid-screenshots.spec.ts Playwright test to capture screenshots
- Add npm run generate:screenshots command (Docker-based for Santa compatibility)
- Add sharp dependency for image resizing with centered-fill mode
- Generate grid-cell.png for 14 example servers (only React for basic-server-* series)
The screenshots are 300x300 PNG images cropped with centered fill mode,
suitable for use in a grid layout showcasing the examples.
* docs: add example gallery grid to README
Add a 3-column visual grid showcasing 14 example MCP Apps with:
- Thumbnail screenshots (300x300 grid-cell.png)
- Clickable links to example directories
- Hover tooltips with brief descriptions
Organized by visual impact: 3D/WebGL examples first, then
visualizations, charts, monitoring, and starter templates.
* fix: use aspect-fit instead of crop for screenshots
Change from fit: 'cover' (crops) to fit: 'contain' (letterbox)
so the full app content is visible without cropping.
* feat: improve screenshot generation
- Constrain viewport to 500px width for consistent rendering
- 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
- Improve Three.js default scene: isometric rotation + better lighting
- Update README: Starter Templates row with links to all framework variants
(React, Vue, Svelte, Preact, Solid, Vanilla JS)
- Regenerate all screenshots with updated settings
* fix: improve README gallery layout
- Fix uneven column widths by using minimal separator
- Move Starter Templates to separate 2-cell table with description
- Add screenshot.png to top of each example README (13 examples)
- Shorten tooltips for cleaner table
* revert to document.write again; cesiumjs doesn't like srcdoc, period.
* fix: map-server screenshot now renders properly
- Merged ochafik/post-fixes which reverts sandbox from srcdoc to document.write
(CesiumJS doesn't work with srcdoc iframes)
- Fixed map-server name in screenshot test ('Map Server' not 'CesiumJS Map Server')
- Simplified screenshot generation script (removed complex debugging code)
- Increased map-server wait time to 45s for reliable tile loading
- Regenerated all 13 screenshots
* fix: remove redundant screenshots from READMEs
Remove the simple \ line from READMEs that
already had nicer HTML table screenshots. Keep it only for examples
that didn't have existing screenshots.
* docs: move gallery to Examples section
- Move screenshot gallery from top of README to Examples section
- Remove redundant list of basic examples (now shown visually in gallery)
- Clean up duplicate run instructions
* fix: remove empty header row from starter templates table
* fix: remove empty header rows from both tables
* fix: add prettier-ignore to prevent table header expansion
* feat: use custom screenshot for video-resource-server
- Use better screenshot from PR #253 comment showing actual video playback
- Skip video-resource-server in screenshot generation script
- Add SKIP_SERVERS set for manually maintained screenshots
* fix: revert unrelated map-server name change
* fix: use correct server name 'CesiumJS Map Server' in screenshot test
* chore: release 0.4.0
* chore: add new examples to npm publish workflow
Add map-server, shadertoy-server, and transcript-server to the
publish-examples matrix.
Introduces a new MCP App example that renders ShaderToy-compatible GLSL
fragment shaders in real-time using WebGL 2.0 and ShaderToyLite.js.
Features:
- Standard ShaderToy uniforms (`iTime`, `iResolution`, `iMouse`, etc.)
- Multi-pass rendering with buffers A-D for feedback effects
- Shader compilation error overlay
