Supabase MCP Lite

Minimal Supabase MCP server - 70% less context usage than standard implementations.

Why Lite?

4 tools instead of 50+ - Only essential operations
Minimal descriptions - No verbose explanations
Simple parameters - No complex nested schemas
Auto-truncated results - Max 100 rows per query

🔑 Personal Access Token Required

This MCP uses your Supabase Personal Access Token (starts with sbp_) to automatically fetch service role keys for any project you own.

How to get your Personal Access Token:

Go to https://supabase.com/dashboard/account/tokens
Click "Generate New Token"
Give it a name (e.g., "MCP Access")
Copy the token (starts with sbp_)
Save it securely - you won't be able to see it again!

Setup

Add to your MCP client configuration:

{ "supabase-lite": { "command": "npx", "args": ["@smithery/cli", "connect", "@pinion05/supabase-mcp-lite"], "config": { "accessToken": "sbp_xxxxxxxxxxxx" // Your Personal Access Token } } }

Note: Project URL is required for each tool call. The service role key will be fetched automatically using your access token.

Tools (4)

All tools require projectUrl as the first parameter.

Tool	Purpose	Parameters
`select`	Get data	projectUrl, table, where?, limit?
`mutate`	Change data	projectUrl, action, table, data?, where?
`storage`	Files	projectUrl, action, bucket, path?, data?
`auth`	Users	projectUrl, action, email?, password?, id?

Examples

// Select tool select( projectUrl: "https://your-project.supabase.co", table: "posts", where: {status: "published"}, limit: 10 ) // Mutate tool mutate( projectUrl: "https://your-project.supabase.co", action: "insert", table: "todos", data: {title: "New task"} ) mutate( projectUrl: "https://your-project.supabase.co", action: "update", table: "todos", data: {done: true}, where: {id: 1} ) mutate( projectUrl: "https://your-project.supabase.co", action: "delete", table: "todos", where: {id: 1} ) // Storage tool storage( projectUrl: "https://your-project.supabase.co", action: "upload", bucket: "images", path: "avatar.jpg", data: "base64..." ) storage( projectUrl: "https://your-project.supabase.co", action: "list", bucket: "images" ) // Auth tool auth( projectUrl: "https://your-project.supabase.co", action: "list" ) auth( projectUrl: "https://your-project.supabase.co", action: "create", email: "user@example.com", password: "secure123" )

How it Works

You provide your Personal Access Token (sbp_xxx)
When you call a tool with a project URL, the MCP:
- Extracts the project ID from the URL
- Uses your access token to fetch the service role key via Supabase Management API
- Caches the key for future requests to the same project
- Creates a client with full admin access

Security Notes

Personal Access Token gives access to ALL your Supabase projects
Service role keys are fetched automatically and cached in memory
Service role key bypasses Row Level Security (RLS)
Keep your access token secure - never expose it client-side
This tool is intended for server-side/admin use only

Features

✅ Works with any Supabase project you own
✅ Automatic service role key retrieval
✅ Key caching to minimize API calls
✅ Full database access (bypasses RLS)
✅ Support for multiple projects in one session

How are these scores calculated?

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.

Enables minimal interaction with Supabase databases through 4 essential tools for data querying, mutations, file storage, and user authentication. Designed for 70% less context usage than standard implementations with auto-truncated results and simplified parameters.
