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 | $0.01414 | $0.01414 |
| Opus 5 | $0.00707 | $0.00707 |
| Sonnet 5 | $0.00283 | $0.00283 |
| Haiku 4.5 | $0.00141 | $0.00141 |
Grade A, and why
mcp AGENTS.md scanned grade A with 1 finding 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 4d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

AGENTS.md - StealthSurf MCP Server
Project Context
This is a stateless MCP proxy server that maps StealthSurf VPN API endpoints to MCP tools. It allows AI agents to manage VPN configurations, cloud servers, paid options, and user profiles through natural language.
Architecture
- Runtime: Node.js 22+, TypeScript, ES modules
- MCP SDK:
@modelcontextprotocol/sdkwith Streamable HTTP transport - Transport: Stateless — each POST creates fresh McpServer + transport
- Auth:
stlth_*API key fromAuthorization: Bearerheader, forwarded to backend API - No framework: Raw
http.createServer+ MCP SDK transport

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 AGENTS.md is an instructions file published in the GitHub repository StealthSurf-VPN/mcp (3 stars, last pushed 4mo ago), licensed MIT. It adds 1,414 tokens to every session, about $0.0071 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
