supabase-nextjs-server MCP Server

A Model Context Protocol server

This is a TypeScript-based MCP server that implements a simple notes system for NextJS. It demonstrates core MCP concepts by providing:

Features

Require NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY environment variables

create_note - Create new text notes
- Takes title and content as required parameters
- Stores note in server state

summarize_notes - Generate a summary of all stored notes
- Includes all note contents as embedded resources
- Returns structured prompt for LLM summarization

Install dependencies:

npm install

Build the server:

npm run build

For development with auto-rebuild:

npm run watch

To use with Claude Desktop, add the server config:

On MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json On Windows: %APPDATA%/Claude/claude_desktop_config.json

{
  "mcpServers": {
    "supabase-nextjs-server": {
      "command": "/path/to/supabase-nextjs-server/build/index.js"
    }
  }
}

Since MCP servers communicate over stdio, debugging can be challenging. We recommend using the MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access debugging tools in your browser.
