StealthGuard 402 — questions
Answers built from our own checks of this server.
What can StealthGuard 402 do?
It exposes 15 tools, read directly from the server on our last check. Among them: alpha_polymarket_whale_orderflow, base_trending_tokens, defi_yield_radar, hackernews_ai_digest, oracle_perp_funding_and_basis, polymarket_alpha_divergence and 9 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is StealthGuard 402 mostly used for?
Its tools cluster around security, polymarket and research. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is StealthGuard 402 working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 80 of 80 checks got a reply (100.0%), average response time 382 ms. The bar chart above shows every period we have measured.
Did StealthGuard 402 ever remove tools?
Yes. arxiv_agent_papers, base_new_pools, crypto_sentiment_pulse, github_trending_agents and 5 more are no longer exposed — we recorded the date each one disappeared. A tool vanishing usually means a breaking change for anything that depended on it.
How do I connect StealthGuard 402?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does StealthGuard 402 need an API key?
No. StealthGuard 402 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 15 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is StealthGuard 402?
It answers our handshake in 382 ms on average, which is faster than 33% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is StealthGuard 402 open source?
We cannot say either way: written in Python and 0 stars on GitHub, but we could not determine the licence, and without one the code is not open source by default.
