How to add a Supabase database with Claude Code
Supabase scores 5/5 on our Claude Code fit scale: official Anthropic-marketplace plugin with MCP server + 2 skills. These steps use only Supabase’s and Anthropic’s official instructions; each step links its source.
-
1
Have Claude Code and a Supabase account ready
You need Claude Code installed and an account with Supabase (supabase.com). Some tools only need the account when the agent first calls a live tool.
-
2
Install the official Supabase plugin
Run this in Claude Code (or your terminal, as the source shows):
/plugin install supabase@claude-plugins-official -
3
No marketplace setup needed
This plugin is in Anthropic’s official marketplace (claude-plugins-official), which Claude Code adds automatically the first time you start an interactive session.

4
Connect and verify
Run /mcp inside a Claude Code session to see connected servers, check status and complete sign-in where the server uses OAuth.

5
Let the skills do the SDK work
The plugin bundles 2 skills that Claude loads when relevant, or you can call one directly with /skill-name.

Then just ask
Example prompt (our suggestion, not from vendor docs):
“Help me add a Supabase database in this project. Follow the Supabase skills, keep secrets in environment variables, and show me the plan before changing files.”
