Seismolog

the seismograph for agent trust

Agents are learning to find other agents, tools and shops on their own: through DNS records, agent cards, MCP server cards, commerce profiles, OAuth metadata and payment declarations that websites publish. Should an agent trust what it finds there, and has any of it changed lately?

Seismolog watches these records across the web and writes down every change in a public, append-only log, with the evidence behind each entry. It works like Certificate Transparency, applied to agents. It records facts and never scores, ranks or judges anyone.

Recording since 9 October 2026

The log is running and public at log.seismolog.org. Anyone who has seen one of its signed checkpoints can check that the history since then has only grown and was never rewritten.

Tools to read it come later: a trust check for any domain or agent, a readiness check for your own site, adoption statistics, and detection of lookalikes that pose as known brands.
