Django ORM Lens MCP server

Django ORM Lens is a helper that reads your Django project's code and explains how your data is structured. It works by looking at the files directly, so it does not need a database or a running server. It is handy for developers who work with Django and want quick answers about models and relationships.

What this MCP server does

You ask your AI a question about your Django project, like which app owns a model or how two models are linked. The AI uses this helper to read your project files. The helper parses the models and migrations without starting Django. Then it sends back a clear answer, often as a list or a diagram description. You get the information in the chat, ready to use.

What you can do with it

• List every app and model in your project
• Describe one model with its fields and relations
• Show an entity-relationship diagram of your schema
• Find N+1 query loops and suggest fixes
• Check which migrations might lock tables or fail
• Suggest missing database indexes
• Show how signals are connected to models

Try asking your AI

• “Which app owns the Order model and how is it connected to User?”
• “Show me the fields of the blog.Post model.”
• “Are there any N+1 query problems in my project?”
• “What risky migrations do I have?”

What it gives back to you

It gives back lists of apps and models, descriptions of single models, Mermaid or DBML diagrams, and findings about N+1 loops or migration risks. In the chat, you see this as text, tables or code blocks you can copy. For diagrams, you get the diagram code you can paste into a viewer. It does not change your files; it only reads and reports.
