Available tools 4

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

analyze

analyze_wallet

Look up a specific wallet's worth-copying read (copyability / Realizability Score / risk) by address. venue 'hl' (Hyperliquid) or 'pm' (Polymarket).

copyable

find_copyable_traders

List Hyperliquid traders that are actually copyable AND realizable for a follower, pre-gated by copy-lag decay, de-leverage, and alpha-vs-beta (NOT raw leaderboard PnL). Returns copyability tier, Realizability Score 0-100, risk grade, PnL, return, copy-lag tolerance. Use when you need vetted copy candidates, not noisy 'top trader' lists.

traders

find_pm_traders

List Polymarket wallets with copyability classification (edge-family), PnL, edge-per-dollar, drawdown, category, invisible-maker volume. PM is structurally near-uncopyable; useful for edge-family research.

vaults

find_vaults

List Hyperliquid vaults ranked by allocation-worthiness (Sharpe, drawdown, operator skin-in-game, concentration, fees). Vaults are deposit products. Returns verdict, risk score, CAGR, max drawdown, TVL, APR.

Signals — questions

Answers built from our own checks of this server.

What can Signals do?

It exposes 4 tools, read directly from the server on our last check. Among them: analyze_wallet, find_copyable_traders, find_pm_traders, find_vaults. 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 →

Is Signals working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 90 of 91 checks got a reply (98.9%), average response time 183 ms. The bar chart above shows every period we have measured.

How do I connect Signals?

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 Signals need an API key?

No. Signals completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 4 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is Signals?

It answers our handshake in 183 ms on average, which is faster than 70% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
