About
Crypto market-signal MCP tools (regime, sentiment, price, risk) via RapidAPI. Needs RAPIDAPI_KEY
Security Report
7.8
Moderate7.8Low RiskA well-structured MCP server for crypto market signals backed by RapidAPI endpoints. Authentication is properly delegated to RapidAPI (RAPIDAPI_KEY via environment variable), no hardcoded secrets are present, and input validation uses Zod schemas. The server has appropriate permissions for its purpose (network_http to RapidAPI, env_vars for credentials). A test-only internal proxy secret exists but is clearly documented and isolated to testing, and does not affect production security.

Stelar Signals MCP
An MCP (Model Context Protocol) server that gives any MCP-compatible AI agent (Claude Desktop, Claude Code, Cursor, etc.) six crypto market-signal and utility tools, backed by the same classifier that runs a live production grid-trading system, plus Claude-powered text tools.
This package ships with no secrets of ours. Each user brings their own free or paid RapidAPI key — see "Get a key" below.
Tools
| Tool | What it does |
|---|---|
crypto_regime | Market regime (chop / trend_up / trend_down / high_vol) + grid-suitability verdict for SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA |
crypto_sentiment | Sentiment score (-1..+1) + label for free text or a crypto asset's recent price action |
summarize | 3-5 sentence LLM summary of a URL or raw text |
factcheck | true/false/uncertain verdict + confidence + reasoning for a claim |
pricecheck | Price, 24h/7d change, bullish/bearish/neutral signal for a major crypto asset |
token_risk | Volatility/drawdown risk regime (low/med/high) vs 30-day baseline, for position sizing |

Sign up, subscribe to a plan, and copy your X-RapidAPI-Key from the
RapidAPI dashboard's code snippet for this API — that snippet also shows the
exact gateway host to use if it differs from the default below.

Honest capability notes
crypto_regime,pricecheck, andtoken_riskcover 8 major pairs only (SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA) — not arbitrary tokens.crypto_sentiment,summarize, andfactcheckare LLM-backed (Claude Haiku) — treat outputs as a fast first-pass signal, not ground truth.factcheckreturnsuncertainfor opinions, unverifiable claims, or anything requiring live data the model doesn't have.summarizewith aurlfetches the page server-side; very large or JS-rendered pages may summarize poorly or fail — passtextdirectly for best results.- All tools are rate-limited by your RapidAPI plan; the free tier (50/mo) is for evaluation, not production load.
- Data source is the same market-data/classifier pipeline that runs a live grid-trading bot — it is a decision-support signal, not investment advice.
