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.

Configuration

Pricing (RapidAPI subscription, not this package)

This npm package itself is free and MIT-licensed. You pay RapidAPI directly for API usage above the free tier; Stelar Digital never sees or stores your key.

Honest capability notes

• crypto_regime, pricecheck, and token_risk cover 8 major pairs only (SOL, XLM, BTC, ETH, XRP, DOGE, LTC, ADA) — not arbitrary tokens.

• crypto_sentiment, summarize, and factcheck are LLM-backed (Claude Haiku) — treat outputs as a fast first-pass signal, not ground truth. factcheck returns uncertain for opinions, unverifiable claims, or anything requiring live data the model doesn't have.

• summarize with a url fetches the page server-side; very large or JS-rendered pages may summarize poorly or fail — pass text directly 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.
