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

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

Or in any MCP client config:

{
  "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:

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

GET https://api.stelardigital.com/catalog          endpoints, prices, parameters
GET https://api.stelardigital.com/.well-known/x402 x402 discovery manifest
GET https://api.stelardigital.com/openapi.json     OpenAPI 3.1 spec

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.
