Stelar Signals MCP

모든 MCP 호환 에이전트(Claude Code, Claude Desktop, Cursor, Windsurf, Codex …)에 실시간 암호화폐 시장 신호와 포트폴리오 텔레메트리를 제공하는 MCP(Model Context Protocol) 서버입니다.

여섯 개 도구는 x402를 통한 호출당 결제 방식입니다 — 가입도, 계정도, API 키도 필요 없습니다. 에이전트가 자체 지갑에서 Base의 USDC로 몇 센트를 결제하면, 같은 요청에서 데이터를 돌려받습니다.

설치

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

또는 모든 MCP 클라이언트 설정에서:

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

서버는 환경 변수 없이도 시작되어 모든 도구를 나열합니다.

이 도구들은 https://api.stelardigital.com을 호출하며, 이 엔드포인트는 결제 챌린지와 함께 HTTP 402로 응답합니다. x402를 지원하는 모든 클라이언트는 이를 결제하고 자동으로 재시도합니다. 지원 자산: SOL, BTC, ETH, XRP, DOGE, LTC, ADA, XLM.

실제 시장 데이터를 기반으로 하는 라이브 프로덕션 엔드포인트입니다 — 데모 스텁이 아닙니다.

무료 티어 도구 — RapidAPI 키가 필요합니다

crypto_regime, crypto_sentiment, pricecheck, token_risk, summarize, factcheck는 RapidAPI를 통해 제공됩니다. 사용하려면 RAPIDAPI_KEY를 설정하세요:

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

키가 없으면 이 여섯 개는 명확한 오류를 반환합니다. 위의 여섯 개 유료 x402 도구는 계속 작동합니다. RapidAPI를 전혀 사용하지 않기 때문입니다.

솔직한 제한사항

  • 신호는 위에 나열된 8개 주요 자산만 다루며, 임의의 토큰은 다루지 않습니다.

  • 유료 도구는 자금이 입금된 지갑이 필요합니다. 없으면 데이터 대신 HTTP 402를 반환합니다.

  • 모든 응답에는 generated_at이 포함되며, 1분 이상 캐시되지 않습니다.

Available Tools

6 tools
crypto_regimeCrypto market regime classifierAInspect

Market regime (chop / trend_up / trend_down / high_vol) for a major crypto pair, powered by the same classifier that steers a live production grid-trading bot. 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.

NameRequiredDescriptionDefault
assetYesAsset symbol, one of: SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA
crypto_sentimentCrypto / text sentiment scorerAInspect

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.

NameRequiredDescriptionDefault
textNoFree text to score (omit if using `asset`)
assetNoAsset symbol to score sentiment for (omit if using `text`)
factcheckFact-check a claimAInspect

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.

NameRequiredDescriptionDefault
claimYesThe factual statement to verify
pricecheckCrypto price + change snapshotAInspect

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.

NameRequiredDescriptionDefault
assetYesAsset symbol, one of: SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA
summarizeURL / text summarizerAInspect

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.

NameRequiredDescriptionDefault
urlNoPage URL to fetch and summarize
textNoRaw text to summarize directly
token_riskCrypto volatility / drawdown risk regimeAInspect

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.

NameRequiredDescriptionDefault
assetYesAsset symbol, one of: SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA

TDQS

A4.2/5.0

Scored across 6 tools

Disambiguation4/5

Most tools are distinct, but crypto_regime and token_risk both describe risk/regime for crypto assets, which could cause confusion despite different focuses (market vs. volatility). Other tools like pricecheck, sentiment, factcheck, and summarize are clearly separated.

Naming Consistency4/5

All names use snake_case and are descriptive, but there is a mix of single-word names (factcheck, pricecheck, summarize) and crypto-prefixed names (crypto_regime, crypto_sentiment, token_risk). No major inconsistencies, but not perfectly uniform.

Tool Count5/5

With 6 tools, the server is well-scoped for a crypto signals service. Each tool serves a clear purpose without being overwhelming or too sparse.

Completeness4/5

The set covers market regime, sentiment, price, risk, fact-checking, and summarization. Minor gaps exist (e.g., no on-chain data or advanced technical indicators), but the core signal needs are addressed. The inclusion of general-purpose tools (factcheck, summarize) is a slight deviation from the crypto focus.
