Rewrites the Quickstart tutorial to provide a more focused, step-by-step
introduction to building MCP Apps. The guide now uses synced code fences
that pull from `examples/quickstart/`, ensuring all code shown in the
documentation is type-checked and tested.
Key improvements:
- Clearer project setup instructions with explicit commands
- Streamlined explanations of the tool + resource registration pattern
- Added screenshot showing the completed app
- E2E test coverage validates the example works end-to-end

* 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: publish example servers to npm
Make example MCP App servers publishable to npm under the
@modelcontextprotocol scope:
- server-basic-react
- server-basic-vanillajs
- server-budget-allocator
- server-cohort-heatmap
- server-customer-segmentation
- server-scenario-modeler
- server-system-monitor
- server-threejs
- server-wiki-explorer
Changes:
- Remove `private: true` from example package.json files
- Add proper npm metadata (description, repository, license, files)
- Update ext-apps dependency from relative to ^0.2.2
- Copy server-utils.ts into each package for standalone use
- Add publish-examples job to npm-publish.yml workflow
The examples will be published automatically when a GitHub release
is created, after the main SDK package is published.
