CoreModels
io.github.aramai-schematica/coremodels is a MCP server that lets agents administer CoreModels schemas, mixins, relations, and JSON Schema exchange after OAuth sign-in.
About
io.github.aramai-schematica/coremodels connects coding agents to the CoreModels hosted schema editor so you can evolve structured domain models without clicking through a separate admin UI for every change. Through streamable HTTP MCP, authenticated developers manage nodes, mixins, and relations and move definitions in and out via JSON Schema—useful when you are defining entities for a SaaS API, agent memory graph, or internal data dictionary during Build. OAuth protects the admin endpoint, so this fits teams already on CoreModels rather than greenfield JSON-schema-only repos. developers benefit when an agent can propose relation fixes or import an OpenAPI-derived schema in one session. It does not replace application code generation by itself; it centralizes the canonical model layer your backend and docs can align to.
- Remote streamable-http MCP at go.coremodels.io/mcp-admin with OAuth 2.0 Bearer sign-in.
- Edit nodes, mixins, and relations in the CoreModels schema editor from the agent.
- JSON Schema import and export for interoperability with existing API contracts.
- Sign-in required; Authorization header is mandatory on every remote call.
- Hosted product CoreModels v1.0.0 with website at aramai.net/products/coremodels.

What it does
Let your agent edit CoreModels schemas—nodes, mixins, relations—with JSON Schema import/export over authenticated remote MCP.
Who is it for?
Best when you use CoreModels and want Claude or Cursor to maintain schema structure and import/export JSON Schema on the hosted admin MCP.
Skip if: Projects that need a local-only schema tool with no OAuth or no CoreModels account.
What you get
Signed-in agents can create and refine CoreModels graphs and sync JSON Schema so backend and documentation stay aligned.
- Agent-driven updates to nodes, mixins, and relations in CoreModels
- JSON Schema import/export artifacts aligned to your product model
By the numbers
- Remote MCP version 1.0.0 at go.coremodels.io/mcp-admin

FAQ
Who is io.github.aramai-schematica/coremodels for?
Developers and PM-developers on CoreModels who want agents to edit structured models and relations instead of manual dashboard work.
When should I use io.github.aramai-schematica/coremodels?
During backend modeling when you are defining entities, mixins, and relations or importing JSON Schema before implementation.
How do I add io.github.aramai-schematica/coremodels to my agent?
Complete OAuth from /.well-known/oauth-protected-resource, add the remote MCP URL https://go.coremodels.io/mcp-admin with Bearer Authorization in Claude Code or Cursor.
