v2.1.0Apache-2.0 AND ISC

Google developer platforms with live docs: the Google Developer Knowledge MCP (developer.android.com, developer.chrome.com, web.dev, Firebase, Google Cloud) plus two skills — android-compose (Android/Kotlin/Compose, Gradle/AGP 9, Nav 3, testing, performance, widgets, Media3) and chrome-web (MV3 extensions, Web Store publishing, Baseline web platform APIs).

Android & Chrome (Google Dev) plugin

Google developer platforms with live docs. Replaces the android plugin (uninstall it first; same MCP URL, so the existing Google Developer connector and sign-in are reused).

Components

ComponentWhat it does
MCP google-developerhttps://developerknowledge.googleapis.com/mcp — search_documents, get_documents, answer_query over developer.android.com, developer.chrome.com, web.dev, Firebase, Google Cloud, ai.google.dev, Flutter/Dart, Go, Maps, Workspace
Skill android-composeRecon-first Android/Kotlin/Compose: architecture, Gradle/AGP 9, Nav 3, testing, Compose performance, ANRs, R8, security, identity, widgets, Media3/Cast, on-device AI. Builds through CI
Skill chrome-webManifest V3 extensions (runtime traps, permissions, side panel, userScripts), Chrome Web Store publishing, Baseline-aware web platform APIs. scripts/check_mv3.py static check + headless Chromium load test

Other Google products (Firebase, Cloud, Gemini API, Maps) need no skill: query the MCP directly.

Surfaces

  • claude.ai chat / Cowork: skills + the remote MCP. The cloud sandbox has Playwright Chromium for extension load tests.
  • Claude Code / Codex: same, plus npx modern-web-guidance@latest for Google's curated web guides. Google recommends an API key in the X-Goog-Api-Key header for the MCP — set it in the client's MCP config, never in this plugin.

twojstar package

Canonical source here is the portable plugin.json + mcp.json + skills/; the Claude Code marketplace entry and the Codex overlay are generated (plugins/_shared/).

python -m pip install -r plugins/_shared/requirements.txt
python plugins/_shared/package_plugin.py plugins/google /tmp/google-2.1.0.zip

Claude Code: /plugin install google@twojstar (after /plugin marketplace add travnie/twojstar).
