AlloyDB for PostgreSQL

[!NOTE] Currently in beta (pre-v1.0), and may see breaking changes until the first stable release (v1.0).

This repository packages MCP Toolbox's prebuilt alloydb-postgres server as a plugin/extension to interact with AlloyDB for PostgreSQL instances. It can be used with various AI agents, including Antigravity, Claude Code and Codex, to manage your databases, execute queries, explore schemas, and troubleshoot issues using natural language prompts.

[!IMPORTANT] We Want Your Feedback! Please share your thoughts with us by filling out our feedback [form][form]. Your input is invaluable and helps us improve the project for everyone.

Why Use AlloyDB for PostgreSQL?

  • Seamless Workflow: Integrates seamlessly into your AI agent's environment. No need to constantly switch contexts for common database tasks.
  • Natural Language Queries: Stop wrestling with complex commands. Explore schemas and query data by describing what you want in plain English.
  • Full Lifecycle Control: Manage the entire lifecycle of your database, from creating instances to exploring schemas and running queries.
  • Code Generation: Accelerate development by asking your agent to generate data classes and other code snippets based on your table schemas.
