Installation

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"

  }
}

Installing via Smithery

To install Supabase Notes for Claude Desktop automatically via Smithery :


npx -y @smithery/cli install @tengfone/supabase-nextjs-mcp-server --client claude

Debugging

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.
