Guide Origin: Official | ArcKit Version: [VERSION]
/arckit.gcp-research researches Google Cloud services, architecture patterns, and implementation guidance using the Google Developer Knowledge MCP server for authoritative documentation.
Agent Architecture: This command runs as an autonomous agent via the Task tool. The agent makes 15-30+ MCP calls to gather Google Cloud documentation in its own context window, keeping the main conversation clean. The slash command is a thin wrapper that delegates to the agent.
This command requires the Google Developer Knowledge MCP server to be installed. It will not work without it.
API Key Required: Unlike AWS Knowledge and Microsoft Learn MCPs (which are free/unauthenticated), the Google Developer Knowledge MCP requires an API key. Get one from Google AI Studio or the Google Cloud Console.
Installation:
Add to your Claude Code MCP configuration (~/.claude/claude_desktop_config.json or project .mcp.json):
{
"mcpServers": {
"google-developer-knowledge": {
"type": "http",
"url": "https://developerknowledge.googleapis.com/mcp",
"headers": {
"X-Goog-Api-Key": "${GOOGLE_API_KEY}"
}
}
}
}Set the environment variable:
export GOOGLE_API_KEY="your-api-key-here"After installation, restart Claude Code to load the MCP server.

/arckit.gcp-research Research Google Cloud services for <project>Outputs: projects/<id>/research/ARC-<id>-GCRS-v1.0.md
Auto-versioning: Re-running this command when a document already exists automatically increments the version (minor for refreshed content, major for changed scope) instead of overwriting.
/arckit.gcp-research frequently exceeds 10 minutes as the agent issues dozens of Google Developer Knowledge MCP calls and fetches full documentation pages for cost and compliance analysis. To avoid babysitting the terminal, pair it with Claude Code Remote Control:
claude remote-controlDrive the session from claude.ai/code or the mobile app, then enable /config → Push when Claude decides so your phone gets a notification on completion or when the agent reaches a decision point (service shortlist confirmation, region selection). ArcKit's minimum Claude Code floor (v2.1.121) already covers the v2.1.110 RC requirement.
Caveats: Pro/Max plans only (no API keys, no Bedrock/Vertex/Foundry), push is a single on/off so chatty agents can over-notify, and the local claude process must keep running.
The command uses three Google Developer Knowledge MCP tools:
| Tool | Purpose |
|---|---|
search_documents |
Search Google Cloud documentation for services, patterns, best practices |
get_document |
Retrieve complete documentation pages for detailed analysis |
batch_get_documents |
Fetch multiple related documentation pages in a single call |
- Google Cloud Service Recommendations: Mapped to specific requirements (FR, NFR, INT, DR)
- Architecture Pattern: Reference architecture from Google Cloud Architecture Center
- Architecture Framework Assessment: All 6 pillars evaluated per service
- Security Command Center: Finding categories and CIS Benchmark for GCP
- UK Government Compliance: G-Cloud, europe-west2 region, NCSC principles
- Cost Estimates: Monthly and 3-year TCO with optimization recommendations
- Implementation Guidance: Terraform templates, Cloud Build pipelines
When UK Government project detected:
| Area | Coverage |
|---|---|
| G-Cloud | Framework reference, service IDs, procurement steps |
| Data Residency | europe-west2 (London) availability, cross-region replication |
| Classification | OFFICIAL, OFFICIAL-SENSITIVE suitability |
| NCSC | 14 Cloud Security Principles alignment |
| Note | No Google Cloud Government UK (US-only) — not suitable for SECRET |
