MCP data layer for AI-assisted market research. 13 live finance tools that drop into Claude Code, Cursor, Cline, Windsurf, or any MCP-compatible client. Free tier requires no signup.

Not a signal service. Not investment advice. Public market data with light enrichment for AI agents. Backtest before acting.

Two ways to use it

Option 1: hosted MCP (zero install). Point your agent at the hosted endpoint, no Python needed.

{
  "mcpServers": {
    "falsifylab-alpha": {
      "url": "https://mcp.falsifylab.com/"
    }
  }
}

Free tier auto-applies. OAuth 2.1 + PKCE flow for paid plan via Whop. Streamable HTTP transport. Full OpenAPI 3.1 spec at https://docs.falsifylab.com/openapi.html.

Option 2: stdio (this package).

pip install falsifylab-alpha-mcp

Zero runtime dependencies (Python stdlib only). Then wire to your agent. see client setup.

What it does

When the user asks your AI agent things like:

"What insider clusters are forming today?"
"Show me Hyperliquid vaults with sharp Sharpe and <10% drawdown"
"Are BTC ETF flows confirming or diverging from price action?"
"What's in the macro tape right now?"
"Find Polymarket whales with 60%+ win rate"

...the agent calls one of 13 tools and grounds its answer in real-time numbers from public-market data — instead of speculating from training-data knowledge.

The 13 tools

| Tool | Returns | Use case | |------|---------|----------| | top_yield_farms | DeFi yields with emissions stripped, IL risk priced | Find real yield, not headline yield | | hl_vault_leaderboard | Hyperliquid vaults by NAV / 30d / drawdown / score | Copy-trade reference | | insider_buy_clusters | SEC Form 4 cluster buys (3+ insiders, 24h window) | Equity conviction signal | | sec8k_material_today | 8-K filings filtered by material item codes | Earnings, M&A, officer changes | | macro_tape | SPX/NDX/VIX/UST/DXY/GOLD/WTI/BTC/ETH snapshot | Regime gate for trade ideas | | etf_flow_today | US spot BTC + ETH ETF aggregates | Institutional positioning | | active_airdrop_farms | DefiLlama yield-gap airdrops | Farms where you're paid to wait | | polymarket_whale_positions | Top wallets + active positions | Prediction-market copy-trade | | earnings_drift_radar | Post-earnings drift + IV-crush candidates | Equity event-volatility scanner | | token_unlock_radar | Forward token unlock schedule + size | Supply-overhang risk radar | | fed_comm_radar | Fed speaker/event volatility windows | Macro event-risk scanner | | confluence_today | Cross-source signal alignment | Stacks 2+ signals on same asset | | onchain_smart_wallets | Live Solana copy-trade bot scores | Production wallet rankings |

All tools have full JSON schemas exposed at /.well-known/mcp/server-card.json.

Client setup

Claude Code

claude mcp add falsifylab-alpha -- python -m falsifylab_alpha_mcp

For Pro tier:

claude mcp add falsifylab-alpha \
  --env FL_API_KEY=fl_your_key \
  -- python -m falsifylab_alpha_mcp

Cursor

Drop into ~/.cursor/mcp.json or workspace root .mcp.json:

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

Restart Cursor. Tools auto-discovered.

Cline

Settings → MCP Servers → Add Server. Paste the same JSON as Cursor above.

Windsurf

Settings → MCP. Same JSON config. Auto-indexed from Smithery within 48h.

Smithery

Connect via Smithery's hosted gateway — no local Python install needed. See smithery.ai/servers/falsifylab/falsifylab-alpha-mcp.

Verify install

In your agent, ask:

Use macro_tape. Show me SPX, VIX, BTC, ETH with 1d and 5d returns.

If the agent returns numbers, you're live.

Working agent prompts

Copy-paste these. They work on first run.

Daily macro brief: `` Use macro_tape. Tell me the macro regime in 3 sentences. Cite specific numbers — last price, 1d return, 5d return. Then list 2 tickers from sec8k_material_today that might benefit from this regime. ``

Insider + 8-K stacker: `` Run insider_buy_clusters (min_insiders=3) and sec8k_material_today (items=["2.02","8.01","5.02"]). Find tickers in both within 24h. For each match, summarize what insiders bought and what the 8-K said. End with the bear case in one sentence. ``

Confluence scan with bear case: `` Use confluence_today with min_signals=2. For each asset/ticker, explain why these signals stacking is meaningful in 2 sentences. Skip noise (DeFi LP pools with stablecoins). Highlight the most contrarian stack. ``

Live demo

Public agent calling these tools every 15 minutes: falsifylab.com/demo. Same MCP server you'd install. Real numbers, no curation.

Why this exists

Built it because the author hand-scraped SEC EDGAR and DefiLlama at 6am every morning to feed a fleet of trading bots. The bots that survived ate from this exact pipeline. Wrapped it as an MCP server so any agent can pull the same data.

The bot fleet receipts (alive + dead, P&L, drawdown) are public at falsifylab.com/vaults.

Transparency

What we do: aggregate + lightly enrich public market data, expose via MCP
What we don't: trade execution, brokerage, advisory, signal selling
Data sources: SEC EDGAR (Form 4, 8-K), SoSoValue (ETF flows), DefiLlama (yield), Hyperliquid public API, Polymarket public API, Yahoo Finance (macro)
Privacy: free-tier key issued by hash(IP+UA), not stored long-term. Request bodies never logged.

Telemetry

The local stdio server writes minimal per-tool telemetry JSONL rows to:

/var/log/falsifylab/mcp_tool_calls.jsonl (override with FL_MCP_TOOL_CALL_LOG)

Each row includes only:

ts, tool, args_keys (argument names only), has_api_key, key_hash (sha256 prefix), version

Never logged by this telemetry path:

raw API keys
argument values / request bodies
IP address
email / name / other user identifiers

To disable telemetry completely:

export FL_DISABLE_TELEMETRY=1

What works, what does not

Honest list. Updated every release.

What works today

All 13 tools return live data inside agent calls under 1s p95.
Free tier has zero signup friction. No API key needed for the cached path.
Form 4 insider clusters get refreshed every 15 min on weekdays from SEC EDGAR direct, no 3rd-party reseller in the pipeline.
DefiLlama yields are emissions-stripped (headline APY minus reward tokens), so a 200% farm and a 200% farm are not the same number any more.
Hyperliquid vault NAV updates hit our R2 mirror within 60s of the source ticker.
Telegram + Slack webhook delivery on Pro Plus is on-time within the cron window. No queue backups in the launch month.

What does not work (yet)

8-K material filings list is empty over weekends because SEC does not file. Returns count: 0 Sat/Sun. Expected.
Macro tape uses Yahoo Finance free endpoints. Intraday gap of 15-20 min during US market hours. We plan to swap for a paid feed at Teams tier, not before.
onchain_smart_wallets only covers Solana right now. Base + Ethereum copy-trade scores are queued for v0.3.x.
Free tier cache is 24h. So confluence_today on a free key shows yesterday's confluence, not today's. Pro $19/mo plan hits live.
Historical replay across multiple quarters is not in v0.2.x. Tracking as roadmap item.
No SDK for TypeScript or Go yet. Python MCP server only. Use stdio transport from any MCP-compatible client meanwhile.

What we already killed

Stripe Connect direct subscriptions (operator KYC blocker). Whop is the path.
Substack paid plan (Stripe dependency).
A previous package version 0.2.0 shipped a broken api.falsifylab.com host. Fixed in 0.2.1 within 4 days. Apologies if you grabbed 0.2.0 first.

If you find something broken, dm the FL X account or open an issue. We ship fixes inside the same day for prod-blocking bugs.

Architecture

your AI agent
    ↓ (MCP stdio)
falsifylab_alpha_mcp (Python stdlib, no deps)
    ↓ (HTTPS)
falsifylab.com/api/* (Cloudflare Workers)
    ↓ (cached 60s-1hr)
R2 (data feeds refreshed every 15min via cron)
    ↓ (every 15min)
Backend cron scripts (Form 4, 8-K, ETF, yield, polymarket, onchain, etc.)

Free tier hits cached data with 24h age. Pro tier hits the same endpoints with auth header, bypasses cache to fresh upstream.
