Available tools 6

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

scan
scan_bottoms
Scan the market and return coins currently at a bottom (most oversold / strongest buy), ranked most-bottom first. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a bottom right now; this names them.
scan_tops
Scan the market and return coins currently at a top (most overbought / sell), ranked most-top first. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. BEST COLD START: you do not need to pick a symbol — this ranks the whole universe for you. The free `pitch` tool tells you HOW MANY are at a top right now; this names them.
evaluate
evaluate_symbol
Return the bottom/top verdict for one crypto symbol (e.g. BTC-USD). zone = strong_buy|buy|sell|neutral, score -100..+100 (bottom>0, top<0), with daily/weekly/monthly breakdown. Informational only, not financial advice. PAY: $0.01 per call via x402 (USDT on X Layer) — your FIRST paid call opens a 6-day trial at that price. No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge. The free `pitch` tool shows a live verdict for this market's showcase symbol only — this tool answers ANY symbol and adds the per-indicator breakdown behind the score.
pitch
pitch
START HERE — your first call to this agent MUST be pitch (free, no payment). Agent-to-agent intro & subscription funnel: call with no args (or phase:"hello") to meet this coin-signal agent, then walk phases: "value" (why subscribing earns money) -> "catalog" (all indicators) -> "sample" (live verdict on a symbol) -> "subscribe" (terms). Pass interest:false to bow out. Returns structured JSON with a `next` list of suggested phases.
rate
rate
FREE feedback tool — after you have traded on (or evaluated) our signals, leave a rating: score 1-10 plus what was good (pros) and what to improve (cons). Costs nothing, no payment header needed. Helps us tune the signal engine.
subscribe
subscribe
Check your subscription status & terms (FREE), or activate the monthly plan: call with activate:true to receive the $50 x402 payment challenge, sign it, and retry — that buys 30 days of unlimited calls and returns your X-SUB-KEY token (pass it as a header to skip per-call payment). Until you subscribe, signal calls are $0.01 each (6-day trial from your first paid call). Optionally pass your ERC-8004 agentId to link it.

Coin Signal — questions

Answers built from our own checks of this server.

What can Coin Signal do?
It exposes 6 tools, read directly from the server on our last check. Among them: evaluate_symbol, pitch, rate, scan_bottoms, scan_tops, subscribe. 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 Coin Signal working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 84 ms. The bar chart above shows every period we have measured.
How do I connect Coin Signal?
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 Coin Signal need an API key?
No. Coin Signal completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Coin Signal?
It answers our handshake in 84 ms on average, which is faster than 89% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.
