New MCP — FalsifyLab Alpha: 10 live finance tools for AI coding agents (free tier)

Showcase Built for Cursor
1

TL;DR: 10 finance tools as an MCP server. Drop into Cursor, Cline, Windsurf, Claude Code in 30 seconds. Free tier real (24h cached, 10 results/query, 60 req/hr), no signup.

What it does

Live data on:

  • DeFi yields (emissions stripped — real yield not headline yield)
  • Hyperliquid vault leaderboard (NAV, 30d, drawdown, composite score)
  • SEC Form 4 insider buy clusters (3+ insiders, 24h window)
  • SEC 8-K material filings filtered by item code
  • US macro tape (SPX, NDX, VIX, UST, DXY, GOLD, WTI, BTC, ETH last + 1d, 5d)
  • US spot BTC + ETH ETF flows
  • DefiLlama airdrop yield-gap detection
  • Polymarket whale positions ($10k+)
  • Cross-source confluence (2+ signals stacking same asset)
  • Onchain smart-wallet copy-trade scores (Solana)

Why

Same pipeline that feeds a live trading bot fleet. Built so my agents can pull SEC + DeFi data without writing 10 separate scrapers.

Install in Cursor

~/.cursor/mcp.json or workspace .mcp.json:

{
  "mcpServers": {
    "falsifylab-alpha": {
      "command": "python",
      "args": ["-m", "falsifylab_alpha_mcp"],
      "env": {"FL_API_KEY": "fl_xxx_optional_for_pro_tier"}
    }
  }
}

Then pip install falsifylab-alpha-mcp once and restart Cursor.

in case it helps for that thread: hosted MCP for SEC filings and on-chain signals. paste into your cursor config like any other server:

{
“mcpServers”: {
“falsifylab-alpha”: {
“url”: “https://mcp.falsifylab.com/”,
“env”: {“FL_API_KEY”: “”}
}
}
}

10 tools: form 4 clusters, 8-K material items, ETF flow, polymarket whales, HL vaults, DeFi yields, airdrops, plus a cross-source confluence tool. free
tier with no signup gets 10 results per call. signed webhooks shipped this week if you need push instead of poll.

update for anyone who installed last week: just shipped a “what works, what does not” section to the readme.
things like 8-k empty over weekends, macro tape lag from yfinance, solana-only smart-wallets right now. felt
cleaner than letting people discover those edges inside their agent loop.

also wrote up a short post on how to wire the pip install to your cursor mcp config in 2 commands, since cf logs
showed 1027 installs week 1 but almost nobody hit /api/* yet. happy to hear if the wiring step is what is blocking
