What is the MCP Database Server?

The MCP Database Server is a middleware service that allows AI models to securely query relational databases (MySQL/PostgreSQL) via standard protocols without direct database access. It provides table structure information and read-only query functions to ensure data access security.

How to use the MCP Database Server?

The usage process is divided into three simple steps: 1) Configure database connection information. 2) Query table structure. 3) Execute read-only SQL queries. All operations are completed through the MCP protocol to ensure standardization and security.

Applicable Scenarios

It is most suitable for scenarios where AI models need to access enterprise databases while ensuring data security, such as read-only data access requirements for data analysis assistants and intelligent report generation.

Main Features

Multi-database Support
Supports both MySQL and PostgreSQL, two mainstream relational databases
Table Structure Access
Provides database table structure information as a resource to help AI models understand the data structure
Read-only Query
Ensures that all queries are read-only through transactions to protect data security
MCP Protocol Compatibility
Fully complies with the Model Context Protocol standard and seamlessly integrates with other MCP components
Advantages
Security Isolation: AI models do not need to directly access the database, reducing security risks.
Standardized Interface: The unified MCP protocol simplifies the integration process.
Transaction Guarantee: All queries are executed in read-only transactions to prevent data modification.
Lightweight and Efficient: Implemented in TypeScript with high operating efficiency.
Limitations
Only supports read-only operations and does not support data writing.
Currently only supports MySQL and PostgreSQL.
Requires pre-configuration of database connection information.

How to Use

Install the Service
Clone the repository and install dependencies using cnpm
Configure the Database
Copy the .env.example file and edit the database connection information
Start the Service
Build and start the MCP server
Connect and Use
Connect and use the service functions through the MCP client

Usage Examples

Get the Structure of the Products Table
The AI assistant needs to understand the structure of the products table to generate correct queries
Query Sales Data
Querying sales data is required to generate a report on last month's sales volume
Explore the Database
Understand which tables are available in the database when using it for the first time
