SchemaFlow
SchemaFlow is a powerful tool designed to enhance AI-powered development by providing real-time access to your PostgreSQL database schema through the Model Context Protocol (MCP). It allows developers to connect their databases, visualize schema structures with interactive diagrams, and export schemas in various formats such as JSON, Markdown, SQL, and Mermaid. With native MCP support via Server-Sent Events (SSE), SchemaFlow enables seamless integration with AI-Integrated Development Environments (AI-IDEs) like Cursor, Windsurf, and VS Code, ensuring that AI assistants have up-to-date schema information for accurate code generation. It offers secure token-based authentication for MCP connections, automatic schema synchronization to keep AI assistants informed of any changes, and a schema browser for easy navigation of tables and relationships.

ERDPlus
A database modeling tool for creating entity relationship diagrams, relational schemas, star schemas, and SQL DDL statements. ERDPlus is a web-based database modeling tool that lets you quickly and easily create Entity Relationship Diagrams (ERDs). Works with most contemporary RDBMS tools including Oracle, MySQL, Microsoft SQL Server, PostgreSQL, Teradata, IBM DB2, Microsoft Access, and others. The notation supports drawing regular and weak entities, various types of attributes (regular, unique, multi-valued, derived, composite, and optional), and all possible cardinality constraints of relationships (mandatory-many, optional-many, mandatory-one, and optional-one). The tool supports the quick creation of foreign keys and referential integrity lines by simple click-point-connect actions. This simplifies and quickens the process of creating relational schemas. The notation distinguishes fact tables from dimension tables by using a thicker frame around fact tables.
