What is the Stelar MCP server?

Stelar MCP server is a hosted integration for AI assistants that speak the Model Context Protocol. Crypto market-signal MCP tools (regime, sentiment, price, risk) via RapidAPI. Needs RAPIDAPI_KEY.

What you get

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.

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

What the assistant can call

Once Stelar is connected, these are the calls the assistant has available:

  • 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
  • telemetry — $0.005
  • sentiment — $0.005
  • price — $0.005
  • risk — $0.02
  • regime — $0.03
  • gridparams — $0.05

Configuration and credentials

You will need 4 environment variables: RAPIDAPI_KEY, YOUR_RAPIDAPI_KEY, RAPIDAPI_HOST, BASE_URL. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

  • Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Stelar.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the stelar mcp server does with a few real requests.

Choosing this one

This sits in the AI and media services group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Stelar's toolset — crypto_regime, crypto_sentiment, summarize and 11 more — is a fair guide to whether it matches your workflow. It is maintained by StelarDigital; worth a glance at recent repository activity before you build anything load-bearing on it.

Frequently asked questions

It connects Stelar to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (crypto_regime, crypto_sentiment, summarize, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Stelar directly.
