Jozu Hub
What it is
Jozu Hub is a registry for models, agents, MCPs, and skills. It checks artifacts before they run and provides governance and auditability, with model versioning, lineage, and deployment tracking. Teams can use the hosted Sandbox or deploy Hub on-premises or in a private cloud; Jozu also supports operation in fully air-gapped environments without a cloud dependency.
Hub scans nine vulnerability classes, including malicious code, backdoored weights, data poisoning, prompt injection, and license violations. Teams can compare ModelKit versions side by side and trace artifact history from experiments through production. At pull time, Hub can compose Rapid Inference Containers from a hardened base image and a ModelKit without a build step. Its registry API implements the MCP registry specification for centrally curated servers in clients such as VS Code, Cursor, and Claude Desktop. Jozu says Hub is commonly accessed from CI/CD tools such as GitHub Actions and GitLab, and experiment trackers such as MLflow. The free Sandbox costs nothing and includes unlimited public repositories, one private repository, and 250 GB of storage. Jozu describes its intended users as enterprises, regulated industries, and governments.
