What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as remote - your agent's requests go to api.sequenzy.com

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

license no standard license detected - usage rights unclear; check the repo before commercial use

registry registry publisher io.github.polnikale is not the repo owner (sequenzy) - the registry entry was published by someone else
