Add SchemaFlow MCP Server

[CryptoRadi]

Description

Adding SchemaFlow MCP Server - a real-time PostgreSQL & Supabase schema access server that provides AI-IDEs with live database context via Server-Sent Events (SSE).

Server Details

• Server: SchemaFlow (new server)
• Changes to: Adding new MCP server with schema extraction tools and real-time updates

Motivation and Context

AI developers working with databases need real-time access to schema information for accurate code generation. SchemaFlow solves this by:

• Providing live PostgreSQL/Supabase schema data to AI-IDEs
• Enabling smarter database-aware code generation
• Supporting real-time schema updates via SSE
• Offering a hosted solution that doesn't require local server setup

How Has This Been Tested?

• ✅ Tested with Cursor IDE using SSE configuration
• ✅ Tested with Windsurf IDE
• ✅ Tested with VS Code + Cline extension
• ✅ Verified schema extraction for PostgreSQL databases
• ✅ Verified schema extraction for Supabase projects
• ✅ Tested real-time schema updates and caching

Breaking Changes

• No breaking changes - this is a new server addition

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Checklist

• I have read the MCP Protocol Documentation
• My changes follows MCP security best practices
• I have updated the server's README accordingly
• I have tested this with an LLM client
• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have documented all environment variables and configuration options

Additional context

SchemaFlow uses a unique SSE (Server-Sent Events) approach instead of traditional stdio/transport methods, making it ideal for web-based integrations and real-time updates. The server is hosted at https://schemaflow.dev and provides:

• get_schema tool for retrieving database schema information
• Real-time schema caching and updates
• Support for both PostgreSQL and Supabase
• Web-based dashboard for database management
• Token-based authentication for secure access
