Supabase MCP Server

Supabase MCP server created in Python. Exposed over MCP by the supabase mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

A Model Context Protocol (MCP) server that provides tools for interacting with a Supabase database. This server enables AI assistants to perform database operations through a standardized interface.

• Read Table Rows — Query data from Supabase tables with optional filtering, pagination, and column selection
• Create Table Records — Insert new records into Supabase tables
• Update Table Records — Modify existing records in Supabase tables based on filters
• Delete Table Records — Remove records from Supabase tables based on filters

Adding it to your client

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.

Configuration

You will need 2 environment variables: SUPABASE_URL, SUPABASE_SERVICE_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

• Docker or Docker Desktop - Supabase account and project

When to reach for it

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. It is maintained by coleam00; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Supabase's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

• It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the supabase mcp server does with a few real requests.
