About this server
Arca is a private data vault where your AI stores your structured data, semantic memory and skills.
Hosted — runs on the provider's infrastructure; connect over HTTP/SSE. Indexed under Other, alongside 726 other servers. Health is freshness-derived from the registry's last-update timestamp; this index does not run the server, so capabilities and tool lists live in the source repository.
