What
Claude Code can now connect to Claude running on Google Cloud infrastructure via claude.googleapis.com, using Application Default Credentials or an explicit bearer token provider.
Usage
# Set your GCP project and let Claude Code discover the workspace
export ANTHROPIC_GOOGLE_CLOUD_PROJECT=my-gcp-project
export ANTHROPIC_GOOGLE_CLOUD_LOCATION=us-east5 # optional, defaults to global
export ANTHROPIC_GOOGLE_CLOUD_WORKSPACE_ID=my-workspace
# Or provide a full base URL directly
export ANTHROPIC_GOOGLE_CLOUD_BASE_URL=https://claude.googleapis.com/v1alpha/projects/...
# Enable the Google Cloud path
export CLAUDE_CODE_USE_ANTHROPIC_GOOGLE_CLOUD=true
# Skip auth entirely (if your infrastructure handles it externally)
export CLAUDE_CODE_SKIP_ANTHROPIC_GOOGLE_CLOUD_AUTH=trueDetails
- Routes to
https://claude.googleapis.com/v1alpha/projects/{project}/locations/{location}/workspaces/{workspace}/invoke - Authenticates using Google Application Default Credentials (ADC) automatically when no other auth is provided — no API key required
- Accepts an explicit
bearerTokenProvidercallback, agoogleAuthobject, or anauthClientdirectly - The deprecated text Completions API is not available on this provider
- GCP environment variable values for project, workspace, and location are validated to only contain letters, digits, hyphens, and underscores — URL metacharacters that could rewrite the request path are rejected with a clear error
- The
anthropicGoogleCloudprovider is now recognized in the provider enum in SessionStart hooks and other SDK schema positions
Evidence
AnthropicGoogleCloud client implementation (search for "Claude Platform on Google Cloud", "https://claude.googleapis.com", ANTHROPIC_GOOGLE_CLOUD_PROJECT)
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
