Why the dossier is worth having

A company proves ownership to every SaaS product it buys by placing a DNS verification record, and authorises every sender it uses in its SPF record. Those two lists are a purchase history the company published itself.

Asking for figma.com returns Anthropic, OpenAI, Adobe, Atlassian, MongoDB Atlas, Greenhouse, Docusign, Stripe, Notion, Dropbox and Zendesk — each with the exact record that proves it, so you can check rather than trust.

Page fingerprints require a loaded script or CDN host, never a mention. A site listing a vendor's logo among its integrations is not a site that uses it.

Install

{
  "mcpServers": {
    "hosaka": {
      "command": "npx",
      "args": ["-y", "hosaka-mcp"],
      "env": { "HOSAKA_PRIVATE_KEY": "0x…" }
    }
  }
}

HOSAKA_PRIVATE_KEY is a wallet holding a little USDC on Base. It signs payments locally and never leaves your machine — what goes over the wire is a signature, never the key. A few dollars covers hundreds of calls.

Gas is paid by the facilitator, not by you, so the wallet needs USDC only.
