cloudarmor-mcp

A Claude Code plugin that connects to Google Cloud Armor and Cloud Logging to inspect web application firewall denial records. It summarizes blocked requests by rule, highlights possible requests from the organization’s home region, and reviews preview rules without making changes.

In plain words
What is it for?
Use it for Cloud Armor denial analysis, rule review, false-positive checks, and a daily health summary from Cloud Logging.
Why use it?
It helps investigate blocked traffic and possible false positives while keeping the service read-only. It requires a Google Cloud project and a service-account key file configured on the local machine.

Security

Grade A, and why

cloudarmor-mcp scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
