What is the MCP Database Management Server?

The MCP Database Management Server is a tool integrating multiple functions, aiming to simplify data migration, table operations, and query execution between PostgreSQL and SQLite databases. It supports common CRUD operations (Create, Read, Update, Delete) and allows users to easily manage database structures.

How to use the MCP Database Management Server?

You can start the server through simple command - line operations, and then perform database management tasks as needed, such as querying, inserting, modifying, or deleting data.

Applicable scenarios

Suitable for application developers who need to seamlessly switch between different database engines, especially in scenarios involving PostgreSQL and SQLite.

Main Features

CRUD Operations

Supports adding, deleting, modifying, and querying records in the database, such as inserting new data, updating existing records, or deleting unnecessary data.

Data Migration

Can migrate all tables and their data from a PostgreSQL database to an SQLite database, and vice versa.

Table Management

Easily create, modify, or delete table structures in the database.

Advanced Query Execution

Supports running complex custom SQL queries to meet data analysis needs.

Advantages

Supports seamless switching between multiple database engines.

Provides powerful query tools for easy data analysis.

Easy to configure and quickly deploy.

Open - source and free to use.

Limitations

Requires certain database knowledge to fully utilize its functions.

May not support some advanced database features.

Depends on the installation and configuration of the local environment.

How to Use

🚀 Database Project (PostgreSQL and SQLite Management)

This project aims to manage and migrate data between PostgreSQL and SQLite databases, making CRUD operations and database management for applications more flexible.

⚠️ Important Note

Another version of this project supports Server-Sent Events (SSE). See mcpDataBasesSSE on GitHub.

✨ Features

CRUD Operations: ➕ Create, 🔍 query, ✏️ update, and ❌ delete records in PostgreSQL database tables.
Table Management: 🏗️ Easily create, 🛠️ modify, and 🗑️ delete tables.
Data Migration: 🔄 Automatically transfer structures and data to SQLite or other databases.
Advanced Queries: 🧮 Execute custom SQL queries for analysis or maintenance.

📦 Installation

This README doesn't provide specific installation steps, so this section is skipped.

💻 Usage Examples

Basic Usage

1. MCP Server (`main.py`)

Run the MCP server to access database management tools:

python3 main.py

Available tools include:

🔎 query_db(query): Execute a SELECT query and return the results.
➕ insert_db(query): Execute an INSERT statement.
✏️ update_db(query): Execute an UPDATE statement.
❌ delete_db(query): Execute a DELETE statement.
🛠️ modify_table(): Modify the database table structure.

2. Data Migration (`migrate_postgres_to_sqlite.py`)

Run the script to migrate data:

python3 migrate_postgres_to_sqlite.py

Ensure that you configure the connection parameters before running.
