SatScore by BlockQuery

The Bitcoin KYT server for you or your AI agent.

Risk-check any Bitcoin address in plain language — you in Claude, or your agent on its own. 99 sats a check over Lightning. No account, no credit packs, no other chains. That's the point.

99 sats / check · settled over Lightning

One MCP. One chain.

Bitcoin is where illicit value actually settles. We go deep on the one chain that matters — the labels, the lineage, the verdicts — instead of spreading thin across fifty.

However you work

Run it yourself, or hand it to your agent.

The same MCP server and the same 99-sat check, whether a person is asking or an agent is screening on its own.

For you

Use it yourself in Claude. Paste an address or a CSV, ask in plain language, and read the verdict.

For your agent

Give your agent a Lightning balance and it screens counterparties autonomously, paying its own way per call.

Why SatScore

Single-chain depth, agent-native economics.

Built to do one chain properly — and to be paid for, per call, by the agents that use it.

500M+

Bitcoin wallets labelled

Risk scoring backed by one of the largest Bitcoin address-label datasets available — the depth behind every verdict.

Pay per check, never upfront

Connect the MCP

Connect

Generate your Claude command.

Add the SatScore MCP server to Claude or any MCP-capable client, point it at one or more Bitcoin addresses, and ask.

Use an email if you may need help matching payments or tokens later. You can use any identifier instead, but anonymous identifiers cannot be verified or recovered.

Redacted command
claude mcp add \
  --transport http \
  blockquery \
  https://mcp.blockquery.io/mcp \
  --header 'Authorization: Bearer <token shown once>'

The bearer token is shown only once. Treat it like a password. Checks settle over Lightning at 99 sats each.
