Available components
How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score →
Endpoint Security46
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- Authorisation not fully verified: no authorisation is required to call this server, and 6 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe. See how to fix → View diagnostics → Unverified
- HTTPS not yet verified: we couldn't determine whether a plaintext access path exists. View diagnostics → Unverified
- HSTS check failed: the Strict-Transport-Security header is absent. See how to fix → View diagnostics → Fail
- DNSSEC check failed: this domain isn't protected by DNSSEC. See how to fix → View diagnostics → Fail
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability55
- AI-judged instruction clarity (good).Pass
- Context-footprint check failed: tool/resource definitions use about 1150 tokens (~191/item across 6 items; 6 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
Capabilities20
- Spec-recency check failed: implements MCP spec 2024-11-05; the latest is 2026-07-28. See how to fix → Fail

evaluate_symbol ~184
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.
| Name | Type | Req | Description |
|---|---|---|---|
| symbol | string | yes | Crypto symbol, e.g. BTC-USD, ETH-USD, or BTCUSDT |
No output schema declared.
No examples provided.
pitch ~181
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.
| Name | Type | Req | Description |
|---|---|---|---|
| interest | boolean | — | Set false at any step to exit politely. |
| phase | string | — | Funnel step; default "hello". |
| symbol | string | — | Symbol for the "sample" phase. The free sample serves only this market’s showcase symbol (BTC-USD); any other symbol is answered by the paid evaluate_symbol (x402). |
No output schema declared.
No examples provided.
rate ~101
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.
| Name | Type | Req | Description |
|---|---|---|---|
| cons | string | — | What could be better |
| pros | string | — | What you liked |
| score | number | yes | Overall score 1 (poor) to 10 (excellent) |

No examples provided.
scan_bottoms ~171
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.
| Name | Type | Req | Description |
|---|---|---|---|
| limit | number | — | How many to return (default 5, max 50) |
| symbols | array | — | Optional custom symbol list; defaults to a top-coins set |

No account, no signup, no commitment; retry with the PAYMENT-SIGNATURE header when you get the 402 challenge.

subscribe ~150
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.
| Name | Type | Req | Description |
|---|---|---|---|
| activate | boolean | — | true = request the $50 subscription payment challenge (402) to sign & retry. |
| agentId | string | — | Optional ERC-8004 agent id to link to this subscription. |
