remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Integrations

  • Provides enhanced database interactions through Supabase, including SQL query processing, PostgREST API access, SQL to REST conversion, and optimized response formatting for UI components, with improved error handling and authentication.

  • Implements strict TypeScript types for response handling, providing type safety for database interactions and standardized JSON response formats.

Windsurf Supabase MCP Server

A Windsurf-optimized MCP server for Supabase integration

This repository contains a Windsurf-optimized version of the Supabase MCP server, specifically enhanced to work seamlessly with the Windsurf Editor. It builds upon the Model Context Protocol (MCP) standard, adding crucial improvements for better error handling, response formatting, and SQL query processing.

Key Modifications for Windsurf

1. Enhanced Error Handling

We faced several challenges with the original error handling system:

  • Malformed SQL queries would cause silent failures
  • Stream parsing errors were difficult to debug
  • Error messages weren't LLM-friendly

Our solutions:

  • Added structured error responses with detailed context
  • Improved error messages for better LLM understanding
  • Added validation for SQL query structure
  • Enhanced stream error detection and recovery

2. Response Formatting

The original response format had limitations:

  • Inconsistent JSON structure across different response types
  • Missing metadata for UI components
  • Limited type safety

Our improvements:

  • Standardized JSON response format
  • Added metadata for UI component generation
  • Implemented strict TypeScript types
  • Added support for streaming complex data structures

3. SQL to REST Conversion

We enhanced the SQL to REST conversion:

  • Added support for more complex SQL operations
  • Improved query validation
  • Better handling of JOINs and subqueries
  • Enhanced error messages for invalid SQL

4. Authentication & Headers

Key improvements in authentication handling:

  • Flexible API key management
  • Support for bearer token authentication
  • Better header management for PostgREST requests
  • Enhanced security validation

Integration with Windsurf

This MCP server is specifically designed to work with the Windsurf Editor, providing:

  • Seamless database interactions through natural language
  • Real-time query validation and correction
  • Enhanced error messages for better debugging
  • Optimized response formatting for UI components

Example Usage in Windsurf

// Example of enhanced response handling const response = await postgrestRequest({ method: 'GET', path: '/todos?is_completed=eq.false', }); // Response includes metadata for UI components const { data, metadata } = response;

Installation

  1. Clone this repository:
git clone https://github.com/hertzfelt/windsurf-supabase-mcp.git
  1. Install dependencies:
npm install
  1. Configure your Supabase connection:
SUPABASE_URL=your_supabase_url SUPABASE_KEY=your_supabase_key

Usage with Windsurf

This server provides two main tools:

  1. postgrestRequest: Enhanced PostgREST API access
const result = await postgrestRequest({ method: 'GET', path: '/users', });
  1. sqlToRest: Improved SQL to REST conversion
const query = 'SELECT * FROM users WHERE age > 18'; const { method, path } = await sqlToRest({ sql: query });
