### Is the server-noonien MCP server safe to use?

server-noonien scores 90 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the server-noonien MCP server expose?

server-noonien exposes 14 tools: create_entities, create_relations, add_observations, update_entities, update_observations, and 9 more. Their descriptions and schemas cost roughly 613 tokens of context every time the server is loaded.

### Is the server-noonien MCP server still maintained?

server-noonien is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
