English | 日本語

MCP server for Google Cloud Armor WAF log patrol — deny summaries per rule, home-region false-positive checks, and preview (dry-run) rule review, straight from Cloud Logging.

Built for a daily "is the WAF healthy?" patrol: one dailybrief call answers what did we block, did we block anyone we shouldn't have, and are the preview rules ready to promote*.

Documentation:

Tools

All tools are read-only. Counts are hard-capped (default 2000 entries per query) and a capped result is reported as >= N (capped), never as an exact total.

Setup

1. Least-privilege service account

Create a service account with roles/logging.viewer only and download a key. Unlike human accounts, service accounts are not subject to organization re-authentication policies, so an unattended patrol never silently expires.

gcloud iam service-accounts create waf-log-viewer --project=YOUR_PROJECT
gcloud projects add-iam-policy-binding YOUR_PROJECT \
  --member=serviceAccount:waf-log-viewer@YOUR_PROJECT.iam.gserviceaccount.com \
  --role=roles/logging.viewer
gcloud iam service-accounts keys create key.json \
  --iam-account=waf-log-viewer@YOUR_PROJECT.iam.gserviceaccount.com

2. Install

pip install cloudarmor-mcp
# or
uv tool install cloudarmor-mcp

3. Environment variables

4. Optional rules INI

Keep your rule numbering out of prompts and give the reports human-readable labels:

[rules]
101 = block non-home deep-path crawlers
500 = AutoDiscover probe block
1002 = OWASP LFI protection

[home]
; home-region DENYs on these priorities are expected, not false positives
known_normal_priorities = 500, 600

5. Claude Code (plugin)

This repository doubles as a single-plugin marketplace, so Claude Code can install the server for you:

/plugin marketplace add shigechika/cloudarmor-mcp
/plugin install cloudarmor-mcp@cloudarmor-mcp

The plugin launches uvx cloudarmor-mcp and reads the same environment variables described in Environment variables above; export them before starting Claude Code. GOOGLEAPPLICATIONCREDENTIALS still has to point at a service-account key file that exists on your own machine — the plugin can't ship or fetch that file for you, so this server can't be fully configured through the plugin's own settings alone.

uvx must be on the PATH of the process that runs Claude Code — a login shell usually has it, but a GUI-launched app may not; install uv system-wide if the plugin fails to start.

6. Claude Code (manual)

Shortened. The full README is on GitHub.

Nothing above is checked by us. What we check is on the safety report.
