Supabase Database

nice-wolf-studio/claude-code-supabase-skills

A straightforward wrapper around Supabase's REST API for CRUD operations on your database tables. You get helper functions for GET, POST, PATCH, and DELETE that handle auth headers automatically, plus support for all the PostgREST query operators (filtering, ordering, pagination, the works). The documentation is comprehensive with real examples for everything from basic selects to upserts and RPC calls. If you're already using Supabase and want to script database operations from Claude without writing curl commands by hand, this does exactly that. Just set your project URL and API key as environment variables and you're off.

Overview

This skill provides tools for working with Supabase database tables through the REST API. Supports SELECT queries with filtering, INSERT, UPDATE, DELETE operations, and calling RPC functions.

Prerequisites

Required environment variables:

export SUPABASE_URL="https://your-project.supabase.co"
export SUPABASE_KEY="your-anon-or-service-role-key"

Helper script: This skill uses the shared Supabase API helper. Make sure to source it:

source "$(dirname "${BASH_SOURCE[0]}")/../../scripts/supabase-api.sh"

Common Operations

SELECT - Query Data

Basic select all:

source "$(dirname "${BASH_SOURCE[0]}")/../../scripts/supabase-api.sh"

# Get all rows from a table
supabase_get "/rest/v1/your_table?select=*"

Select specific columns:

# Get only id and name columns
supabase_get "/rest/v1/users?select=id,name,email"

Filter results:

# Equality filter
supabase_get "/rest/v1/users?select=*&email=eq.user@example.com"

# Greater than
supabase_get "/rest/v1/products?select=*&price=gt.100"

# Less than or equal
supabase_get "/rest/v1/orders?select=*&quantity=lte.10"
