Summary
On September 10, 2026, Google released the google-cloud-developer plugin, an installable bundle that equips AI coding agents with Google Cloud onboarding, authentication, gcloud CLI guardrails, and current developer documentation through a Developer Knowledge MCP server. It supports Claude Code, Codex, and Antigravity CLI and is published under Apache-2.0 in Google's open-source google/skills repository.
What changed
Google published the open-source (Apache-2.0) google-cloud-developer plugin on September 10, 2026, packaging Google Cloud auth and authorization, project management, gcloud guardrails, and a Developer Knowledge MCP server for grounded docs, with install paths for Claude Code, Codex, and Antigravity CLI using the Agent Plugins 1.0.0 schema.
Why it matters
Cloud vendors are competing to be the default execution target for coding agents; shipping a portable, agent-agnostic plugin rather than a proprietary agent meets developers inside whichever agent they already use and turns MCP-grounded docs and gcloud guardrails into a distribution channel for Google Cloud.
Evidence excerpt
The google-cloud-developer plugin packages Google Cloud onboarding, authentication, gcloud guidance and current developer documentation into one portable plugin, with install paths for Codex, Claude Code and Antigravity, published under Apache-2.0 in the google/skills repository.
