Full read-write Claude connector for Supabase
Let Claude run scoped reads and writes against your Supabase data
Stop hand-writing SQL in the Supabase dashboard for every change. Claude queries your tables, inserts and updates rows, and prepares migrations in the conversation, with each write scoped to your keys and confirmed before it touches your data.
Supabase is an open-source backend platform built on Postgres, giving teams a database, auth, storage, and APIs in one place. People want Claude to query their data, change rows, and manage schema directly, not just describe what the tables hold.
What is a Supabase MCP server?
A Supabase MCP server is a small hosted service that exposes Supabase's data and actions to Claude over the Model Context Protocol, so Claude can records, tables, and queries inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Supabase's current connector do today?
Today, Supabase access through Claude tends to be read-leaning or a thin slice: Claude can often inspect schema and run select-style queries, but inserting, updating, or migrating data is limited or absent. Because the database sits behind project keys and row-level security, write paths usually need a purpose-built connector with scoped credentials.
What does full read-write Supabase access unlock?
Full read-write Supabase access lets Claude insert and update rows, run parameterized queries, apply migrations, and manage storage objects directly against your project. The data work that used to mean hand-writing SQL in the dashboard happens in the conversation, with each write scoped and confirmed before it touches your tables.
- Insert or update rows in a table from natural-language instructions
- Run a parameterized read query and summarize the results
- Apply a schema migration to add a column or index after you approve it
- Upsert records and reconcile duplicates across a table
- Manage storage bucket objects, uploading or removing files
- Draft and run a backfill, then report the affected row count
Can Claude insert and update rows in my Supabase tables?
Yes. Claude can insert and update rows in your Supabase tables from natural-language instructions, including upserting records and reconciling duplicates. The write tools use the scoped database or API credentials you provide, so they inherit your row-level security and never reach further than your own keys already allow.
Can Claude run a read query against my Supabase data?
Claude can run parameterized read queries against your Supabase project, inspect the schema, and summarize what the results show. Read tools and write tools are kept separate, so you can enable safe querying on its own and decide which changes to your data require a confirmation step.
Will Claude run migrations or delete data in Supabase without approval?
No. Schema migrations and deletes are gated write actions in Supabase. Claude can prepare the migration or the delete and show you exactly what it will change, then it only runs once you approve. You choose which actions are automatic and which always pause for a confirmation first.
How a Supabase connector works
We build a small MCP server that connects to your Supabase project with scoped database or API credentials, never broader than the keys you provide. Read tools (query, inspect schema) and write tools (insert, update, migrate) are separated, and destructive actions like deletes or migrations are gated behind your confirmation. If your project is locked to specific networks, we honor IP allowlisting so access stays inside your boundary.
