The plugin enforces least-privilege IAM patterns and requires user consent before enabling billable APIs or modifying cloud infrastructure, and its gcloud skill validates syntax and blocks destructive commands. Installation needs no API keys, OAuth token exchange or configuration-file edits, with Antigravity managing authentication transparently.", "body_md": "Building cloud solutions with autonomous AI agents should feel fast, safe, and reliable. Without cloud-specific context, coding agents often struggle. They might invent deprecated SDK syntax, guess invalid command flags, or attempt operations without the required Identity and Access Management (IAM) permissions. Even worse, an unguided agent can enable billable APIs or provision cloud resources without your explicit permission.\n\nStarting today, you can install the **google-cloud-developer** plugin directly from the Antigravity Marketplace in the `Build with Google` section. This plugin equips Antigravity with foundational skills, safety guardrails, and live documentation grounding for building on Google Cloud. If you've never installed a plugin using the marketplace before, you can refer to the [Antigravity documentation](https://antigravity.google/docs/marketplace/).\n\nConfiguration is straightforward. The bundled Developer Knowledge Model Context Protocol (MCP) server is pre-authorized by default. You don't need to configure API keys, exchange OAuth tokens, or edit any configuration files. You install the plugin, and your agent connects to official Google developer documentation immediately.\n\nIn this post, we'll walk through what's included in the plugin, how to install it with one click, and how it grounds your agent in live Google Cloud documentation.\n\nCoding agents often rely on static training data. Cloud platforms update quickly, and models can produce code with outdated client libraries or invalid parameters.\n\nThe `google-cloud-developer` plugin solves this issue. It bundles curated skills, intelligent routing rules, and the Developer Knowledge MCP server into a single portable package.\n\nThe plugin provides three key benefits:\n\n**Live documentation grounding**: The agent queries official Google Cloud documentation over streamable HTTP.\n\n**Safety and cost guardrails**: The agent enforces least-privilege IAM patterns and it requires your consent before it enables billable APIs or modifying cloud infrastructure.\n\n**Environment awareness**: The agent inspects your local environment, detects existing CLI configurations, and designs safe execution roadmaps before it runs commands.\n\nThe plugin pairs core baseline skills and live documentation grounding with an intelligent skill routing architecture. Rather than limiting your agent to a fixed set of capabilities, it acts as an extensible gateway that discovers and pulls specialized skills from Google on demand.\n\nThe bundled skills provide essential day-one guardrails, live documentation grounding, and the dynamic discovery engine that unlocks the broader catalog:\n\n[**`finding-google-skills`**](https://github.com/google/skills/tree/main/plugins/cloud/google-cloud-developer/skills/finding-google-skills): Powers flexible skill routing by discovering and loading skills on demand from the [`google/skills` repository on GitHub](https://g.dev/ai/skills). Rather than requiring you to research, install, and manage individual skills, it dynamically retrieves the exact instructions your agent needs for specialized tasks in real time.\n\n**retrieving-developer-knowledge**\n\n[**`gcloud`**](https://github.com/google/skills/tree/main/plugins/cloud/google-cloud-developer/skills/gcloud): Enforces execution guardrails, validates syntax, and applies safety checks to Google Cloud CLI (`gcloud`) commands. It blocks accidental destructive operations and it keeps you in control.\n\n**google-cloud-recipe-auth**\n\n**google-cloud-recipe-onboarding**\n\nThe plugin connects your agent to the [Developer Knowledge MCP server](https://developers.google.com/knowledge/mcp). Typically, adding an MCP server requires manual API key handling. With the Antigravity Marketplace integration in the `Build with Google` catalog, this MCP server is pre-authorized: Antigravity manages the authentication transparently. Your agent connects to Google's documentation server immediately after installation.\n\nThe plugin includes `google-cloud-discovery.md`, an active routing rule that works together with the `finding-google-skills` bundled skill. When your prompt touches specialized topics, the routing rule directs the agent to fetch the relevant skills from the public catalog as needed.\n\nThis dynamic routing keeps your agent fast and token-efficient. Instead of preloading dozens of niche skills that clutter the context window, your agent pulls in deep, specialized guidance only when your task requires it.\n\nYou can install the plugin through the Antigravity Marketplace UI or through your terminal.\n\nIf you prefer the command line, install the plugin with a single command:\n\nThe CLI registers the skills and connects the Developer Knowledge MCP server immediately. You can also explore the plugin and skills directly on [GitHub](https://g.dev/ai/skills).\n\nAfter the plugin is installed, your agent automatically grounds its answers in current documentation. You don't need to prompt it with special syntax. Consider a practical query:\n\n\"Based on the documentation what is the main difference between GKE and Cloud Run? When should I use one over the other?\"\n\nWithout the plugin, an agent might guess or provide outdated information. With the `google-cloud-developer` plugin active, the agent queries the pre-authorized Developer Knowledge MCP server:", "url": "https://wpnews.pro/news/google-cloud-developer-plugin-now-available-in-antigravity-marketplace", "canonical_source": "https://cloud.google.com/blog/topics/developers-practitioners/google-cloud-developer-plugin-now-available-in-antigravity-marketplace/", "published_at": "2026-11-02 18:00:00+00:00", "updated_at": "2026-11-02 21:20:45.312945+00:00", "lang": "en", "topics": ["ai-agents", "agent-protocols", "ai-tools", "developer-tools", "ai-products"], "entities": ["Google Cloud", "Antigravity Marketplace", "google-cloud-developer", "Developer Knowledge MCP server", "gcloud", "google/skills"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/google-cloud-developer-plugin-now-available-in-antigravity-marketplace", "markdown": "https://wpnews.pro/news/google-cloud-developer-plugin-now-available-in-antigravity-marketplace.md", "text": "https://wpnews.pro/news/google-cloud-developer-plugin-now-available-in-antigravity-marketplace.txt", "jsonld": "https://wpnews.pro/news/google-cloud-developer-plugin-now-available-in-antigravity-marketplace.jsonld"}}
