VSLZ documentation
Visual reasoning, with a clear contract.
VSLZ gives AI three opinionated MCP tools for charts, diagrams, and networks. Start here to understand the protocol, the visual language, and the connection flow.
VSLZ is client-rendered by design. The server validates the declarative spec and serves the MCP App resource; layout and visualization computation happen in the host device.
