Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01447 | $0.01447 |
| Opus 5 | $0.00724 | $0.00724 |
| Sonnet 5 | $0.00289 | $0.00289 |
| Haiku 4.5 | $0.00145 | $0.00145 |
Grade A, and why
cloudarmor-mcp copilot-instructions.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 3d 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 — 120 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copilot review instructions — cloudarmor-mcp
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.
Review against the properties below. They are specific to this repository — skip generic advice that any Python project would receive.
This is a read-only server, and that is load-bearing
Every tool only reads Cloud Logging. The service account it authenticates with
is expected to hold roles/logging.viewer and nothing else, and the docs tell
operators to create it that way.
- Flag any new call that mutates state (Cloud Armor policy edits, log exclusions, writing back to GCP) — that would break the security model the deployment guide promises, not just add a feature.
- A tool that acquires broader scopes than log reading needs the same scrutiny.
Never let a truncated count read as a total
Queries are capped (CLOUDARMOR_MAX_ENTRIES, default 2000). When the cap is
hit, reports must print >= N (capped at N) — this is what _count_fragment
in server.py exists for.
- A new report path that formats
len(entries)directly, bypassing_count_fragment, is a defect: it turns a lower bound into an apparent exact figure, and the whole point of the cap notation is that a busy day must not be mistaken for a quiet one. _collectreturns(entries, cap)for this reason. A caller that discards the cap loses the ability to flag truncation.
Rule priorities arrive as floats
Cloud Logging returns jsonPayload.*SecurityPolicy.priority as a JSON number,
so a priority shows up as 101.0. _normalize_priority in client.py folds
integral floats back to "101" so they match the plain integers operators
write in the rules INI.
- Any new code path that reads a priority must go through that normalization,
or label lookup and
known_normal_prioritiesmatching will silently miss. - This was a real bug found in the first live run; do not regress it.
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 copilot-instructions.md is an instructions file published in the GitHub repository shigechika/cloudarmor-mcp (0 stars, last pushed 7d ago), licensed MIT. It adds 1,447 tokens to every session, about $0.0072 per session on Opus 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.
