Summary

A developer shares their solution to address Cursor AI's hallucination issues when generating React components with Supabase integration using a Model Context Protocol (MCP) server. The approach provides real-time schema information and type constraints to the AI, resulting in more accurate code generation and improved handling of database relationships and policies.

Prompt

Create a Model Context Protocol (MCP) server that provides real-time Supabase schema information to Cursor AI for React component generation. The server should:
1. Maintain current database schema information including tables, relationships, and RLS policies
2. Provide type definitions for TypeScript
3. Handle foreign key relationships
4. Update automatically when schema changes
5. Integrate with existing React/TypeScript codebase
6. Support real-time schema validation during code generation

Best Practices

Real-time Schema Validation

critical

Implement a dedicated MCP server to provide real-time, accurate schema information to the AI

Dynamic Context Updates

important

Implement automatic context updates that reflect codebase evolution

RLS Policy Integration

critical

Include Row Level Security policies in the schema information provided to AI

Common Mistakes to Avoid

Avoid Static Schema References

critical

Don't rely on static code snippets for database schema information

Prevent Direct Schema Interpretation

important

Don't let AI directly interpret database structures without proper context
