Description

The Self-Hosted Supabase MCP server provides a bridge between MCP clients and self-hosted Supabase instances, enabling database introspection and management directly from development environments. Built from scratch by HenkDz, it offers tools for querying database schemas, managing migrations, inspecting connections, handling auth users, and interacting with storage buckets through a streamlined interface focused on single-project environments. Unlike the official cloud server, this implementation avoids multi-project complexities while maintaining core functionality through both RPC calls and direct database connections, making it ideal for developers working with local or privately hosted Supabase projects.
