Changes since 1.2.1:
- fix(schemas): import from zod/v4 to match SDK's zod API (#548)
- test(e2e): fix no-op security injection test via frames[] traversal (#540)
* docs: restore full MCP client JSON configs to CONTRIBUTING.md
Reinstate the copy-pasteable JSON configurations for running all examples
with MCP clients (npx-based and local development), which were removed
from README.md in 2af02ba. Placed in CONTRIBUTING.md as a better home
for contributor-facing setup instructions.
https://claude.ai/code/session_014pjt7bE4ckHns5QFPkdWQp
* Use start:stdio in local dev config, add missing scripts to 9 examples
Update the local development JSON config in CONTRIBUTING.md to use
`npm --silent run start:stdio` instead of manual bash commands.
Add `serve:stdio` and `start:stdio` scripts to the 9 examples that
were missing them (basic-server-*, sheet-music, transcript,
video-resource, debug) to match the pattern already in place for the
other 11 showcase examples.

* chore: bump ext-apps to 1.1.2
Changes since 1.1.1:
- feat: add ui/download-file method for host-mediated file downloads (#475)
- pdf-server: robust path validation + folder/file root support (#497)
- ci: auto-fix prettier formatting in pre-commit hook and CI (#498)
* fix: sync local SDK build into node_modules for examples
npm workspaces hoists example dependencies to the root node_modules,
but installs the published registry copy of @modelcontextprotocol/ext-apps
instead of linking to the local source. This causes type-check failures
when examples use features not yet published to npm.
Add scripts/link-self.mjs which copies the freshly-built dist/ and
package.json into the hoisted node_modules copy after each SDK build,
ensuring examples always type-check against the latest local types.
See: https://github.com/npm/feedback/discussions/774
* Revert "fix: sync local SDK build into node_modules for examples"
This reverts commit e3387e8434f3def030f5a223a70632092c929119.
Bug fixes / improvements since 1.1.0:
- fix: add audio/video support for basic-host (#460)
- fix(pdf-server): remove page-loading overlay (#493)
- pdf-server: remove domain allowlist, require HTTPS only (#487)
- Set audioSession.type to playback in sheet music app (#489)

- Align basic-host dark mode styles (#438)
Spec:
- Change Host <> Sandbox communication protocol to SHOULD (#435)
- Clarify UIResourceMeta in both list and read responses (#410)
* fix(debug-server): add missing npm package config (main, bin, types, exports)
Align debug-server package.json with all other server examples:
- main: dist/server.js (was server.ts)
- types: dist/server.d.ts
- bin: mcp-server-debug -> dist/index.js
- exports with types
- files: only dist (remove source server.ts)
Single quotes in `concurrently` commands work on Unix shells but not on
Windows Command Shell (`cmd.exe`), causing the `INPUT` environment
variable to not be set and npm scripts to fail with errors like:
'cross-env' is not recognized as an internal or external command
Error: INPUT environment variable is not set
Replace single quotes with escaped double quotes (`\"`) in npm scripts
in all example `package.json` files.

* fix(examples): use npm reference for ext-apps dependency
Replace local path '../..' with '^1.0.0' npm reference in all example
packages. The local path was accidentally published to npm, causing
npm install to hang when installing server-* packages.
Bump versions to 1.0.1 for all public packages to fix the published
versions.
Fixes npm install hanging issue in dependent projects like
example-remote-server.
Note: npm workspaces automatically resolves the dependency to the
local package during development, so no overrides are needed.

* feat(server): add getUiCapability helper for capability negotiation (#313)
* feat(server): add hasUiSupport/getUiCapability for experimental+extensions
Support double-tagging for MCP Apps capability negotiation:
- Check both experimental and extensions fields in client capabilities
- Add hasUiSupport() to easily check if client supports MCP Apps
- Add getUiCapability() to retrieve the capability settings
- Update spec to document both capability locations
This enables forward compatibility as MCP transitions from experimental
to the extensions field (SEP-1724).

* fix: update @types/node version in package-lock.json
Replace invalid 22.19.5/22.19.6/22.19.7 versions with valid 22.19.3
* docs(spec): clarify hosts SHOULD double-tag, servers SHOULD check both
- Hosts SHOULD advertise capabilities in both experimental and extensions
- Servers SHOULD check both locations, preferring extensions when present
- Updated example to show double-tagging pattern
* chore: remove double-tagging recommendation, keep hasUiSupport helper
Reverts the spec changes that recommended clients double-tag capabilities
in both experimental and extensions fields. The helper functions remain
as they're useful for checking capability in either location.
* refactor(server): simplify to only getUiCapability, remove hasUiSupport
- Remove hasUiSupport function (use getUiCapability directly)
- Remove double-tagging logic (only check extensions field)
- Add ClientCapabilitiesWithExtensions type using SDK's ClientCapabilities
- Update spec to use getUiCapability
- Simplify tests
* fix: update @see link to getUiCapability
* refactor(server): inline ClientCapabilitiesWithExtensions type in getUiCapability
* refactor: move McpUiClientCapabilities to spec.types.ts
* fix: update playwright docker image to v1.58.0
* fix: use -i instead of -it for docker commands (no TTY needed)
* fix: Python server dependency resolution and Docker host validation (#333)
* fix(say-server): add --index flag to uv run for PyPI resolution
The pocket-tts dependency wasn't resolving without explicit --index flag
when invoked via npm scripts.
* fix(qr-server): allow Docker bridge IP in transport security
Add 172.17.0.1:* to allowed_hosts to fix 421 Misdirected Request errors
when the server is accessed from Docker containers.
* feat(basic-host): Add theme toggle and MCP style variables (#336)
* feat(basic-host): add theme toggle and MCP style variables
Add theme support to basic-host example:
- theme.ts: Global theme manager with light/dark toggle
- host-styles.ts: Full set of MCP CSS variables using light-dark()
- ThemeToggle component with sun/moon icons
- Theme-aware CSS using CSS custom properties
- Pass theme + styles to apps via hostContext
- Notify apps when theme changes via sendHostContextChange
Apps now receive:
- hostContext.theme: 'light' | 'dark'
- hostContext.styles.variables: All 60+ MCP CSS variables
- onhostcontextchanged notifications when theme changes
* test: update e2e goldens for theme changes
* [MCP Apps] Add appCapabilities.availableDisplayModes documentation to spec (#331)
* Add appCapabilities.availableDisplayModes documentation to spec
Document the availableDisplayModes field in McpUiAppCapabilities that allows
apps to declare which display modes they support. This enables hosts to
compute the intersection of host and app capabilities and only offer
appropriate display mode controls.

* Refactor server startup functions
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.

* Support full-file inclusion in synced code snippets
Previously, the script only supported extracting regions from `.ts/.tsx`
files using the `#regionName` syntax. Now it also supports including
entire files without a region specifier, enabling sync of any file type
(JSON, YAML, shell scripts, etc.) into documentation.
Changes:
- Make `#regionName` optional in the `source=""` attribute
- Accept any fence language (not just `ts`/`tsx`)
- Simplify cache to flat map with composite keys
- Add validation error for region extraction on non-TypeScript files

* Rewrite Quickstart guide with type-checked code examples
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

* Add MCP Apps Overview document
Adds `docs/overview.md` covering the core concepts: architecture,
lifecycle, UI resources, bidirectional communication, theming, display
modes, and security. Includes mermaid flowchart and sequence diagrams.
Also adds the `@boneskull/typedoc-plugin-mermaid` TypeDoc plugin for
mermaid diagram support. However, the plugin handles HTML entities from
TypeDoc incorrectly, so `scripts/typedoc-plugin-fix-mermaid-entities.mjs`
decodes HTML entities before the plugin processes them.

plugin, Vercel Skills CLI (`npx skills add`), and manual installation.
Update `README.md` to link to the new guide and reframe the plugin
section around the broader "Agent Skills" concept.

* Fix mermaid diagram arrowheads not rendering
The `@boneskull/typedoc-plugin-mermaid` creates both dark and light theme
variants of each diagram, each with identical marker IDs (e.g., `#arrowhead`).
When mermaid renders SVGs at runtime, lines reference `url(#arrowhead)`, but
the browser resolves this to the first match in document order — the hidden
dark-theme SVG — causing arrows to be invisible.
The fix removes dark-theme `<div class="mermaid dark">` elements at build time,
leaving only one SVG per diagram with unique marker IDs. A CSS filter
(`filter: invert(1) hue-rotate(180deg)`) handles dark mode styling instead.

* fix(docs): improve OpenAI migration guide accuracy (#349)
- Add missing setOpenInAppUrl API to 'Not Yet in MCP Apps' section
- Clarify Event Handling table: specify exact OpenAI properties

- Improve notes to distinguish sync property reads vs callbacks
* Add Testing MCP Apps guide
Document how to test MCP Apps using `basic-host` and MCP Apps-compatible
hosts like Claude.ai and VS Code Copilot. Cover debugging features for
`basic-host`, and using `cloudflared` to expose local servers for remote
hosts.

* Fix `onhostcontextchanged` handler invocation in examples
`App.onhostcontextchanged` is a setter-only property with no getter.
TypeScript doesn't prevent reading from setter-only properties, so
`app.onhostcontextchanged?.(ctx)` compiles but silently returns
`undefined` at runtime.
Extract the handler into a named `handleHostContextChanged()` function
and call it directly after `connect()`, matching the pattern used in
`basic-server-vanillajs` and other examples.

* Expand Agent Skills guide
Add intro explaining what Agent Skills are and link to the two skill

text and add tip to quickstart suggesting agent skills as an alternative.

examples with `basic-host` vs MCP clients using stdio transport. Move the
`qr` server note outside the collapsed details block.

* 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
