Postgres FAQs

Question 1

What are the technical requirements for deploying and running Postgres?

Accepted Answer

To run Postgres, you'll need Java 17+ and Maven 3.8+ installed, along with access to a PostgreSQL database. It's built using Spring Boot, which simplifies deployment and configuration.

Question 2

What is Postgres and what does it do?

Accepted Answer

Postgres is a Spring Boot server designed to expose PostgreSQL database tools directly to AI clients, such as Claude Desktop, using the Model Context Protocol (MCP). It acts as a secure bridge, allowing AI models to intelligently interact with your database.

Question 3

What AI clients or tools are compatible with Postgres?

Accepted Answer

Postgres implements the MCP Streamable HTTP transport, making it compatible with any MCP-enabled client. This includes popular tools like Claude Desktop, MCP Inspector, and other custom AI applications capable of interacting via the Model Context Protocol.

Question 4

How does Postgres ensure secure interaction with the database?

Accepted Answer

Security is built-in by enforcing read-only `SELECT` statements for all AI-initiated queries. This prevents any unintended data modification. For production environments, further security layers like Spring Security for authentication and using a secrets manager for credentials are recommended.

Question 5

What specific database operations can AI clients perform with Postgres?

Accepted Answer

AI clients can securely perform read-only operations. This includes listing all tables in a database, describing the schema (columns, types, nullability) of a specific table, and executing safe `SELECT` SQL queries to retrieve data. Write operations are strictly prevented.
