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 | $0.00186 | $0.00186 |
| Opus 5 | $0.00093 | $0.00093 |
| Sonnet 5 | $0.00037 | $0.00037 |
| Haiku 4.5 | $0.00019 | $0.00019 |
Grade A, and why
mcp-httpserver-proxy GEMINI.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 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 it actually says
Antigravity / Gemini Workspace Rules
Refer to AGENTS.md for full architecture overview, development workflows, and constraints.
Key Rules
- Never output to stdout (
console.log) in proxy code. All logs must useconsole.errorto avoid corrupting MCP JSON-RPC stdio transport. - Build and Verification: Always verify code changes with
pnpm run build,pnpm run format, andpnpm run check. - Commit & PR Standards: Use Emojified Conventional Commits (
✨ feat:,🐛 fix:,📝 docs:,🔧 chore:, etc.). - Pull Requests: Follow the AI PR workflow detailed in
.agents/skills/create-pr/SKILL.mdwith rich markdown formatting (What, Why, How to Test, Testing Evidence).
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.

mcp-httpserver-proxy GEMINI.md is an instructions file published in the GitHub repository shailesh17/mcp-httpserver-proxy (2 stars, last pushed 9d ago), licensed MIT. It adds 186 tokens to every session, about $0.0009 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.
