Token cost

What it costs to keep this loaded

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.

Security

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.

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/sdk with Streamable HTTP transport
  • Transport: Stateless — each POST creates fresh McpServer + transport
  • Auth: stlth_* API key from Authorization: Bearer header, 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.
