Summary
Connects Claude to a paid SEC EDGAR crypto filing radar that runs on Base USDC micropayments via x402. You get free sample filings through the MCP, plus URLs for the paid buyer pack (complete crypto treasury signals, company summaries, follow-up suggestions), CSV snapshots, individual filing markdown, and general page-to-markdown conversion. The buyer pack costs $10, CSV snapshots $1, individual filings $0.10. Useful when you need current public company crypto disclosure intel without manual EDGAR scraping. The MCP exposes three tools: sample filings, paid URL resolution, and x402 resource discovery. All data is public only, no account-gated sources.
