Overview

What is MCP Server: PostgreSQL Docker Initializer?

This MCP server provides a single tool (init-postgres-docker) that initializes a PostgreSQL database inside a new Docker container. It is designed for developers who need a quick, disposable PostgreSQL instance for development or testing.

How to use MCP Server: PostgreSQL Docker Initializer?

Install dependencies with make install or npm install, build with make build or npm run build, then run the server. Use make inspect to interact via the MCP inspector, or run node build/index.js directly to connect with an MCP client. The tool is invoked by sending a request with a database name.

FAQ from MCP Server: PostgreSQL Docker Initializer

What does the `init-postgres-docker` tool do?

It creates a new Docker container running PostgreSQL with a specified database name, a default user (pguser), and a default password (mysecretpassword), then returns the connection URL.

What are the prerequisites to run this server?

Node.js and npm (or a compatible package manager), Docker (must be running), and Make.

Is the default password secure?

No, the password mysecretpassword is hardcoded and insecure. This server is intended for demonstration purposes only; real-world use should implement a more secure password method.

Does the PostgreSQL container persist after stopping?

No, the container is set to auto-remove (AutoRemove: true). Consider the lifecycle needed for your use case.

How can I run the server without the Makefile?

Install dependencies with npm install, build with npm run build, then run node build/index.js directly or use the MCP inspector with npx @modelcontextprotocol/inspector node build/index.js.
