Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02256 | $0.02256 |
| Opus 5.5 | $0.00902 | $0.00902 |
| Sonnet 5.5 | $0.00451 | $0.00451 |
| Haiku 4.5 | $0.00226 | $0.00226 |
Grade A, and why
cloudarmor-mcp CLAUDE.md 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 20d ago.
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.
How it starts
The opening of the file, as written. The whole thing — 160 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for AI assistants (and humans) editing this repository.
This file covers how to work here: commands, layout, conventions, and
the traps. Two sibling files carry the other halves and are not repeated
here — .github/copilot-instructions.md explains why the invariants
exist, and REVIEW.md decides what a reviewer treats as blocking.
What this repository is
An MCP server that reads Google Cloud Armor WAF deny logs out of Cloud
Logging and reports them: per-rule counts, a home-region false-positive
lens, and preview (dry-run) rule review. Built on the official MCP
Python SDK (mcp.server.fastmcp), published to PyPI as
cloudarmor-mcp.
Read-only by design. Every tool only reads Cloud Logging, and the
service account is documented as holding roles/logging.viewer and
nothing else. That is a security posture the deployment guide promises
to operators, not just a feature boundary.
Commands
uv sync --dev # install, including pytest + ruff
uv run pytest # unit tests (no network, no GCP creds)
uv run ruff check . # lint — gated in CI
uv run ruff format --check . # format — gated in CI (see the trap below)
uv run cloudarmor-mcp --check # live health probe against a real project
uv run cloudarmor-mcp --brief # render the daily brief to stdout
uv run python scripts/smoke_test.py # every tool against a real project
tests/ runs without network access or Google credentials:
test_client.py covers filter construction and config parsing,
test_server.py injects a fake log client. The live check is
scripts/smoke_test.py, run on a schedule against a deployed instance —
it is deliberately not part of the unit suite.
CLI exit codes (cloudarmor_mcp/__main__.py)
CLOUDARMOR_PROJECT is checked first, before either flag is handled, and
exits 1 on its own. So:
| Invocation | 0 | 1 | 2 |
|---|---|---|---|
--version |
always | — | — |
--check |
healthy | CLOUDARMOR_PROJECT unset |
degraded (probe failed) |
--brief |
every section rendered | CLOUDARMOR_PROJECT unset, or any section's query failed |
— |
deny-export |
exported | Cloud Logging query failed, or the reader closed stdout | usage/config error, including CLOUDARMOR_PROJECT unset, a client that cannot be created (credentials) and a day that has not ended |
traffic-export |
exported | as deny-export |
as deny-export, plus a --sample outside 0.000001–1 |
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.

cloudarmor-mcp CLAUDE.md is an instructions file published in the GitHub repository shigechika/cloudarmor-mcp (0 stars, last pushed yesterday), licensed MIT. It adds 2,256 tokens to every session, about $0.0090 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
