mcp.falsifylab.com is live

10 finance tools as a hosted MCP server, zero install, free tier no signup. plus signed webhooks for the paid plan.

i shipped a hosted version of falsifylab-alpha-mcp. you point your AI coding agent at one URL and get 10 finance tools, no pip install, no python, no API key for the free tier.

https://mcp.falsifylab.com/

works in cursor, cline, windsurf, mcp-inspector, anything that speaks streamable HTTP MCP. drop the URL into your mcp config and ask the agent things like "show me insider buy clusters today" or "find polymarket markets where 3+ whales are stacking the same side."

what changed since the stdio launch

three real upgrades.

hosted MCP at mcp.falsifylab.com. before this, you had to pip install and run a stdio subprocess. now the URL just works. free tier auto-applies. zero setup.

OAuth 2.1 proxy. the worker speaks RFC 8414 discovery, RFC 7591 dynamic client registration, RFC 9728 protected-resource metadata, full PKCE flow. paid users sign in once via Whop, the MCP client gets a Bearer JWT, every subsequent tool call carries it. no license-key paste necessary.

(one caveat: the Whop OAuth app needs an oauth:token_exchange permission grant that isn't yet exposed in their dashboard scopes UI. license-key Bearer auth works today. OAuth round-trip lands when Whop support replies.)

webhooks. paid-plan users register a URL at /api/webhooks and receive signed POSTs the moment a new signal fires.

curl -X POST https://falsifylab.com/api/webhooks \
  -H "Authorization: Bearer <your-key>" \
  -d '{"url": "https://yourapp.com/wh", "events": ["confluence.detected"]}'

each delivery carries an HMAC-SHA256 signature in the X-FL-Signature header. spec is at docs.falsifylab.com/guides/use-webhooks.

what's in the 10 tools

how to plug in

cursor / cline / windsurf / any streamable-HTTP MCP client:

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

prefer stdio? pip install falsifylab-alpha-mcp (now at version 0.2.0), drop in the local config from the github README.

what's free and what's $19

free: 24h cached data, 10 results per query, 60 requests per hour. no signup. enough to build with.

paid: $19/mo via Whop. real-time (no cache), 100 results per query, 90d history, webhooks.

why this exists

i run a fleet of trading bots that all need the same plumbing: SEC filings, defi yields, polymarket whales, hyperliquid vaults, onchain wallets. i wrote scrapers anyway. wrapping them as an MCP server means other people's agents can pull from the same pipeline.

no vc. no roadmap PDF. i ship what my own bots need and the public surface is a byproduct.
