Query MCP enables end-to-end management of Supabase via chat interface: read & write query executions, management API support, automatic migration versioning, access to logs and much more.

No outside reports on file

This tool gives an AI direct control over your database, so use only with read-only credentials for non-critical data, never with production databases, and only if you fully trust the AI system.

About Supabase MCP Server

This MCP server lets you manage Supabase databases through a chat interface. You can run read and write queries, access management APIs, track database migrations, and view logs—all by talking to an AI assistant instead of using the Supabase dashboard directly.

Who it’s for

Developers who use Supabase (a Firebase alternative) and want to manage their databases through AI chat. Teams that want to automate database tasks and queries within their AI workflows.

Alternatives

Prisma MCP Server: Manage databases through Prisma ORM instead of direct SQL.
Generic SQL MCP connectors: Direct PostgreSQL or MySQL MCP servers (without Supabase-specific features).
Supabase Dashboard: Use the official web interface instead of AI-mediated access.

Setup

Check these steps against the project’s own instructions before running anything.

Follow the project's README at https://github.com/alexander-zuev/supabase-mcp-server (opens external site) for installation and configuration steps. You'll need to provide your Supabase API credentials (project URL and API keys) to connect.

Risks to watch for

Full database access: The AI gets your Supabase credentials and can read, modify, or delete any data in your database depending on what permissions you give it.
Credential exposure: API keys and secrets stored in configuration files could be leaked if files are accidentally shared or if the server is compromised.
SQL injection risks: If the AI constructs database queries from user input, attackers might craft prompts to run harmful SQL commands you didn't intend.
Unintended data changes: The AI might execute write operations or migrations based on casual conversation, potentially damaging production data.
Log and query leakage: Database queries, logs, and results could contain sensitive customer or business data that gets exposed through AI responses or logs.

How to lower the risk

Least-privilege permissions

Create a Supabase service role or API key with read-only access for testing.
Never use admin credentials or full database access keys.

Network isolation

Run the MCP server on a private network or isolated machine if possible.
Restrict which AI systems can access this connector.

Monitoring

Log all database queries executed through the AI to catch unexpected changes.
Review Supabase audit logs regularly for unauthorized access.

Red flags to watch for

The AI suddenly running DELETE or DROP commands without your request.
Large amounts of data being exported or queries taking much longer than expected.
Error messages revealing database structure or credentials in AI responses.
