概览

AI 生成的概览

让助手获取八种主流加密资产的实时行情信号（价格、情绪、风险、市场状态、网格参数）以及投资组合遥测数据。

可以做什么
  • 查询主流加密资产的现价、24 小时与 7 日涨跌幅及简单多空信号
  • 对文本或资产做情绪评分，并对照 30 日基线评估波动率与回撤风险
  • 判定市场状态（震荡、上涨趋势、下跌趋势、高波动）并给出网格适用性结论，以及推荐的网格交易参数
  • 读取 AI 管理的加密投资组合遥测：配置、已对账盈亏、信号投票与人工审批记录
  • 对网址或文本块生成摘要，并对事实性说法给出核查结论、置信度与简短理由
适用场景
当助手需要为八种受支持的主流币快速获取加密市场背景或交易信号输入时适用，也适合需要托管式摘要与事实核查、而不想自行调用 LLM 或抓取网页的场景。
运行要求
可作为本地 npm 包通过 npx 运行（需 Node.js），也可使用托管的 streamable-HTTP 端点。六个免费层工具需要在 RAPIDAPI_KEY 环境变量中提供 RapidAPI 密钥；六个付费工具无需密钥，但需要支持 x402 的客户端和 Base 上已充值的 USDC 钱包。
安装前请注意
六个工具按次以 Base 上的 USDC 收费（每次 0.005 至 0.05 美元），因此钱包有余额的助手可能自动花钱；未付款的调用会返回 HTTP 402。免费层工具需要 RAPIDAPI_KEY 密钥。请求会发往第三方 API，提交给摘要与事实核查工具的文本或网址也会发送到该服务。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Stelar Signals，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Web executable，通过 Streamable HTTP。 远程服务在工作区中配置后即可从网页运行时运行。

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.

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

12

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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

输入参数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.

输入参数asset必填
