Listed is easy. Proven is the standard.
Other MCP registries are phone books: type your server in and you're listed. sebbi connects to every server, reads every word its tools feed the AI, pins the exact tool list with a fingerprint sealed into Bitcoin, and checks it again every day. If a tool changes after people trusted it, the whole world can see.

What every server goes through
- It answers: a live MCP connection over HTTPS, timed. No answer, no listing.
- It's clean: every tool name, description and schema is scanned for hidden instructions, invisible text, leaked keys and attempts to take over other tools. Every finding shows the exact words.
- It's pinned: the tool list becomes one fingerprint, sealed into sebbi.pro's chain and anchored in Bitcoin.
- It's watched: re-tested daily. A changed tool turns the listing amber until the owner approves it, and both are on the public record forever.
- Anyone can check: an AI client sends the fingerprint of what it sees and gets MATCH or MISMATCH. No need to trust sebbi: the method is published.
