Crypto Social Intel

Crypto social intelligence skill for AI agents. Activate when user mentions social trends, sentiment analysis, KOL signals, mention surge, Fear & Greed Index...

Security Scan

The skill's stated functionality (crypto social signals via Santiment + alternative.me) is coherent, but it instructs the agent to interact with an external MCP endpoint (https://mcp-skills.ai.antalpha.com/mcp) without specifying what user data is sent or who controls that service — this creates a potential privacy/exfiltration risk that isn't documented.

Purpose & Capability

The name, description, tools, and data sources (Santiment + alternative.me) align with the declared functionality (social trending, sentiment, KOL proxy, mention surges, Fear & Greed). There are no unrelated binaries or environment variables requested in the skill metadata. The note that Santiment requires an API key is consistent with the data source.

Instruction Scope

The SKILL.md instructs the agent to initialize and call a remote MCP endpoint (https://mcp-skills.ai.antalpha.com/mcp) to run the five tools. It does not document what payloads are sent, what user context or prompts are forwarded, or the MCP operator's data handling/retention policies. Because the agent will transmit user queries and context to that external service, this is a potential privacy/exfiltration vector not accounted for in the description.

Install Mechanism

Instruction-only skill with no install spec and no code files — nothing is written to disk or auto-installed. This is lower risk from an install/execution perspective.

Credentials

The skill declares no required environment variables for the agent, but the SKILL.md repeatedly states that Santiment API keys are required for the Santiment-backed tools and suggests setting SANTIMENT_API_KEY on the server. That mismatch is explainable (keys may be held by the remote MCP service), but it should be explicit who controls the key and whether user-provided secrets would be uploaded to that service. No unrelated credentials are requested.

Persistence & Privilege

The skill does not request always:true, does not request persistent system config, and is user-invocable only. It does allow normal autonomous model invocation, which is standard for skills.

What to consider before installing

This skill appears to do what it says (crypto social signals from Santiment + alternative.me), but it relies on a third-party MCP endpoint (https://mcp-skills.ai.antalpha.com/mcp). Before installing or invoking it: 1) Ask who operates that MCP endpoint and request their privacy/data-retention policy; confirm TLS, ownership, and whether they log full user prompts or responses. 2) Do not send secrets or private data through the skill — the documentation does not specify what is forwarded. 3) If you need stronger guarantees, ask for source code or a way to run the MCP backend locally (the doc suggests a localhost alternative), or host your own instance and keep your Santiment API key private. 4) If you plan to provide your own Santiment API key, verify how and where it will be stored and who can access it. If any of these questions remain unanswered, consider the skill suspicious and avoid using it for sensitive information.

Protocol: MCP Streamable HTTP (JSON-RPC over HTTP with mcp-session-id header).

Connection Flow

1. POST /mcp → initialize (get mcp-session-id from response header)
2. POST /mcp → tools/call  (with mcp-session-id header)

crypto-fear-greed

Get the Crypto Fear & Greed Index. Real-time, no API key required.

Parameters:

• days (optional): History days to return, 1-30, default 7

Response example:

{
  "current": {
    "value": 23,
    "classification": "Extreme Fear",
    "date": "2026-04-15"
  },
  "trend": "improving",
  "signal_level": "MEDIUM",
  "market_note": "市场偏恐慌，情绪面有支撑，注意底部信号。",
  "history": [...],
  "data_source": "alternative.me"
}

Contrarian signal logic:

• Extreme Fear (≤20) → 🔴 HIGH (historical buy opportunity)
• Fear (21-40) → 🟡 MEDIUM
• Neutral (41-60) → 🟢 LOW
• Greed (61-79) → 🟢 LOW
• Extreme Greed (≥80) → 🔴 HIGH (caution, potential top)

Signal Levels

Level	Condition	Badge
HIGH	sentiment>70 + surge>3x, OR Extreme Fear/Greed	🔴
MEDIUM	sentiment≥50 + surge≥2x, OR Fear	🟡
LOW	otherwise	🟢

Note: crypto-kol-signals signal_level is based on dominance_change (independent of the sentiment+surge rule above). Extreme dominance change (>50% or <-50%) → HIGH; moderate change → MEDIUM; otherwise LOW.

Workflow

Check Market Sentiment (most common)

1. crypto-fear-greed { days: 7 }           ← overall market mood
2. crypto-social-trending { limit: 10 }    ← what's hot
3. Present combined view to user

Analyze Specific Token

1. crypto-sentiment-score { symbol: "ETH" }
2. crypto-kol-signals { symbol: "ETH", threshold: 1.5 }
3. Combine: sentiment score + dominance signal → final assessment

Early Warning Scan

1. crypto-mention-surge { threshold: 2.0, limit: 10 }
2. For tokens with HIGH/MEDIUM signals → crypto-sentiment-score to confirm
3. Alert user to tokens with multiple converging signals

Combined with Smart Money

When social signal + on-chain signal converge:

1. crypto-mention-surge detects abnormal spike
2. → Call smart-money-signal to check if whales are buying
3. Two signals converging → stronger conviction
