CoreModels

Connects Claude to your CoreModels workspace for editing schemas, mixins, and relations directly from chat. You can create and modify JSON Schema definitions, import existing schemas, define typed mappings between models, and export refined structures back out. Requires sign-in to access your organization's schema graph. Useful when you're modeling data structures conversationally and want to persist them in a governed environment rather than copying JSON back and forth. The server exposes CoreModels' node and relationship editing APIs over streamable HTTP, so you can iterate on semantic definitions and transformation rules without leaving your chat context.
