If a tool disappears, we record the date.
crypto
crypto_regime
Market regime (chop / trend_up / trend_down / high_vol) for a major crypto pair, computed from live 24h market structure by a production-grade classifier. 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.
crypto_sentiment
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.
factcheck
factcheck
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.
gridparams
gridparams
PAID PER CALL ($0.05 USDC on Base via x402). Recommended grid-trading parameters (range, spacing, order size) for a pair and capital amount, derived from live 24h market structure. Unpaid calls return the exact x402 payment terms.
price
price
PAID PER CALL ($0.005 USDC on Base via x402). Current price, 24h/7d change, and a simple signal for a major crypto asset. Unpaid calls return the exact x402 payment terms.
pricecheck
pricecheck
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.
regime
regime
PAID PER CALL ($0.03 USDC on Base via x402). Market regime (chop / trend_up / trend_down / high_vol) plus a grid-suitability verdict, computed from live 24h market structure. Unpaid calls return the exact x402 payment terms.
risk
risk
PAID PER CALL ($0.02 USDC on Base via x402). Volatility / drawdown risk regime (low / med / high) vs the 30-day baseline for a major crypto asset. Unpaid calls return the exact x402 payment terms.
sentiment
sentiment
PAID PER CALL ($0.005 USDC on Base via x402). Sentiment score (-1..+1) with label for EXACTLY ONE of `text` or `asset`. Unpaid calls return the exact x402 payment terms.
summarize
summarize
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.
telemetry
telemetry
PAID PER CALL ($0.005 USDC on Base via x402 — no signup, no API key). Telemetry for an AI-managed long-horizon crypto portfolio: allocation, reconciled profit-and-loss, signal votes, and the human-approval trail for every trade. Unpaid calls return the exact x402 payment terms.
token
token_risk
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.

Stelar Signals — questions
Answers built from our own checks of this server.
What can Stelar Signals do?
It exposes 12 tools, read directly from the server on our last check. Among them: crypto_regime, crypto_sentiment, factcheck, gridparams, price, pricecheck and 6 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Stelar Signals working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 639 ms. The bar chart above shows every period we have measured.
How do I connect Stelar Signals?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Stelar Signals need an API key?
No. Stelar Signals completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 12 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Stelar Signals?
It answers our handshake in 639 ms on average, which is faster than 16% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use Stelar Signals?
The npm package stelar-signals-mcp was installed 40 times in the last week. Week over week that is +20%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is Stelar Signals open source?
The code is open source: it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at api.stelardigital.com, which runs on its operator's own terms.
