概覽

AI 產生的概覽

讓助理取得八種主流加密資產的即時行情訊號（價格、情緒、風險、市場狀態、網格參數）以及投資組合遙測資料。

可以做什麼
  • 查詢主流加密資產的現價、24 小時與 7 日漲跌幅及簡單多空訊號
  • 對文字或資產做情緒評分，並對照 30 日基準評估波動率與回撤風險
  • 判定市場狀態（盤整、上漲趨勢、下跌趨勢、高波動）並給出網格適用性結論，以及建議的網格交易參數
  • 讀取 AI 管理的加密投資組合遙測：配置、已對帳損益、訊號投票與人工核准紀錄
  • 對網址或文字區塊產生摘要，並對事實陳述給出查核結論、信心分數與簡短理由
適用情境
適合助理需要為八種支援的主流幣快速取得加密市場背景或交易訊號輸入時使用，也適合需要託管式摘要與事實查核、而不想自行呼叫 LLM 或抓取網頁的情境。
執行需求
可作為本機 npm 套件透過 npx 執行（需 Node.js），也可使用託管的 streamable-HTTP 端點。六個免費層工具需要在 RAPIDAPI_KEY 環境變數中提供 RapidAPI 金鑰；六個付費工具不需金鑰，但需要支援 x402 的用戶端與 Base 上已儲值的 USDC 錢包。
安裝前請注意
六個工具按次以 Base 上的 USDC 收費（每次 0.005 至 0.05 美元），因此錢包有餘額的助理可能自動付費；未付款的呼叫會回傳 HTTP 402。免費層工具需要 RAPIDAPI_KEY 密鑰。請求會送往第三方 API，提交給摘要與事實查核工具的文字或網址也會傳送到該服務。

安裝

在 SourceWeft 中

  1. 開啟 儀表板中的 Stelar Signals，將其新增到工作區。
  2. 為需要使用其工具的對話啟用該服務。

Web executable，透過 Streamable HTTP。 遠端服務在工作區中設定後即可從網頁執行環境執行。

交給代理程式安裝

把這段提示詞貼上到 Claude Code、Codex、Cursor 等代理程式，或 SourceWeft 對話中。代理程式會讀取該伺服器的安裝指南，先向你展示發布者、端點和登入方式，經你同意後再把它新增到你的客戶端。金鑰不會寫進任何命令。

閱讀 https://sourceweft.com/mcp/io.github.StelarDigital%2Fstelar-signals-mcp/install.md，並按其中說明把這個 MCP 伺服器接入我的客戶端。修改任何設定之前，先告訴我它的發布者、端點和登入方式，等我確認。不要把 API 金鑰寫進命令或我會提交的檔案；問我金鑰應從哪裡取得。

README

Stelar Signals MCP

An MCP (Model Context Protocol) server that gives any MCP-compatible agent (Claude Code, Claude Desktop, Cursor, Windsurf, Codex …) live crypto market signals and portfolio telemetry.

Six of its tools are pay-per-call over x402 — no signup, no account, and no API key. Your agent pays cents in USDC on Base from its own wallet and gets the data back in the same request.

Install

bash
claude mcp add stelar -- npx -y stelar-signals-mcp

Or in any MCP client config:

json
{  "mcpServers": {    "stelar": { "command": "npx", "args": ["-y", "stelar-signals-mcp"] }  }}

The server starts and lists every tool with no environment variables set.

Paid tools — x402, USDC on Base, no key required

ToolPriceWhat you get
price$0.005Current price, 24h and 7d change, bull/bear/neutral signal
sentiment$0.005Sentiment score (-1 to +1) and label, for text or an asset
telemetry$0.005Live telemetry of an AI-managed crypto portfolio — allocation, reconciled P&L, signal votes, human-approval trail
risk$0.02Volatility / drawdown risk regime — ATR% vs its 30-day p80 baseline, labeled low/med/high
regime$0.03Market regime (chop / uptrend / downtrend / high-volatility) plus a grid-trading suitability verdict
gridparams$0.05Grid count, spacing %, price band and per-grid allocation from live 24h market structure

These call https://api.stelardigital.com, which answers HTTP 402 with a payment challenge. Any x402-capable client settles it and retries automatically. Assets covered: SOL, BTC, ETH, XRP, DOGE, LTC, ADA, XLM.

These are live production endpoints backed by real market data — not demo stubs.

Free-tier tools — these DO need a RapidAPI key

crypto_regime, crypto_sentiment, pricecheck, token_risk, summarize, factcheck are served through RapidAPI. Set RAPIDAPI_KEY to use them:

bash
claude mcp add stelar -e RAPIDAPI_KEY=your-key -- npx -y stelar-signals-mcp

Without the key these six return a clear error; the six paid x402 tools above keep working, because they do not use RapidAPI at all.

Discovery

A hosted streamable-HTTP MCP endpoint is also live at https://api.stelardigital.com/mcp.

Honest limits

  • Signals cover the eight majors listed above, not arbitrary tokens.
  • Paid tools need a funded wallet; without one they return HTTP 402 rather than data.
  • Every response carries generated_at; nothing is cached longer than a minute.

工具

crypto_regime

Crypto market regime classifier

Market regime (chop / trend_up / trend_down / high_vol) for a major crypto pair, computed from live 24h market structure by a production-grade classifier. Returns a grid_suitability verdict (good/poor/etc) telling an agent whether current conditions favor range-bound (grid) strategies or trend-following ones. Use this before deciding to deploy a grid bot, mean-reversion strategy, or trend-follow strategy on SOL, XLM, BTC, ETH, XRP, DOGE, LTC, or ADA.

輸入參數asset必填

crypto_sentiment

Crypto / text sentiment scorer

Sentiment score (-1 to +1) with a bullish/neutral/bearish label, for either raw text or a crypto asset's recent price action, via an LLM. Give it EXACTLY ONE of `text` (free-form text to score) or `asset` (one of SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA). Useful for agents building trading signals, news pipelines, or social-listening tools without running their own LLM sentiment call.

輸入參數textasset

summarize

URL / text summarizer

Tight 3-5 sentence summary of a URL or a raw text block, via an LLM. Give it EXACTLY ONE of `url` (a page to fetch and summarize) or `text` (raw text to summarize directly). For agents/pipelines that need a fast, information-dense digest without running their own LLM call or web fetch.

輸入參數urltext

factcheck

Fact-check a claim

Fact-check verdict (true / false / uncertain) with a confidence score (0-1) and a 1-2 sentence reasoning for any factual claim, via an LLM. Useful for content moderation, chatbot/agent guardrails, and misinformation screening. Returns 'uncertain' for opinions or claims requiring live/real-time data.

輸入參數claim必填

pricecheck

Crypto price + change snapshot

Current price, 24h and 7d percent change, and a simple bullish/bearish/neutral signal for a major crypto asset. Low-latency market-data lookup for dashboards, bots, and alerts — one of SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA.

輸入參數asset必填

token_risk

Crypto volatility / drawdown risk regime

Volatility / drawdown risk regime (low / med / high) for a major crypto asset, extending the same classifier behind crypto_regime. Tells an agent whether current volatility is elevated vs its 30-day baseline — useful for position sizing and stop-placement logic. One of SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA.
