MCP Server — KOL data
for your AI agent

What it does

The Model Context Protocol (MCP) lets AI assistants call external tools. The CabalSpy MCP server exposes the CabalSpy KOL and Smart Money API as 21 tools an assistant can use on its own: it picks the right tool, fills in the parameters and answers in plain language, with real on-chain data instead of guesses.

It is a remote server — nothing to download or run. All tools are read-only: the server returns data and never signs transactions or touches funds.

Connect in one minute

Get a free key from the API dashboard (10,000 credits per month, no credit card) and replace YOUR_KEY below.

Claude Code

claude mcp add --transport http cabalspy https://mcp.cabalspy.xyz/mcp \
  --header "X-CabalSpy-Key: YOUR_KEY"

Cursor

Use the Add to Cursor button, or add this to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cabalspy": {
      "url": "https://mcp.cabalspy.xyz/mcp",
      "headers": { "X-CabalSpy-Key": "YOUR_KEY" }
    }
  }
}

VS Code

Use the Add to VS Code button, or add this to .vscode/mcp.json:

{
  "servers": {
    "cabalspy": {
      "type": "http",
      "url": "https://mcp.cabalspy.xyz/mcp",
      "headers": { "X-CabalSpy-Key": "YOUR_KEY" }
    }
  }
}

Claude Desktop, claude.ai and other clients

Clients that only take a URL (for example custom connectors in claude.ai) can pass the key as a query parameter:

https://mcp.cabalspy.xyz/mcp?api_key=YOUR_KEY

Where a client lets you set headers, prefer the header — it keeps the key out of logs.

Coverage

Solana has KOL, Smart Money and Whale wallets; BNB Chain, Base and Robinhood Chain have KOL and Smart Money; Ethereum has KOL wallets — 3,000+ labeled wallets in total. Statistics are available for 6 hours, 1 day, 7 days and 30 days. Market cap and price in USD are returned for Solana tokens.

Who uses it

• Traders — research a token or a wallet in a chat instead of five dashboards
• AI agent builders — give a trading or research agent a labeled-wallet data source without writing API glue
• Developers — explore the API from the editor before integrating the REST and WebSocket API
• Analysts — check whether a launch was bundled or which wallets move together
