MySQL MCP server for AI agents

The MySQL MCP Server provides a Model Context Protocol interface for MySQL database access, allowing you to list tables, view schemas, and execute read-only SQL queries with secure connection handling.

Installation

To install the MySQL MCP Server:

Clone the repository to your local machine
Install the required dependencies:
```
npm install
```
Build the project:
```
npm run build
```

Configuration

Before running the server, you need to configure your database connection using environment variables:

# Required variables
MYSQL_HOST=your_mysql_host
MYSQL_PORT=your_mysql_port
MYSQL_USER=your_mysql_username
MYSQL_PASS=your_mysql_password
MYSQL_DB=your_database_name

# Optional variables
MYSQL_SOCKET=path_to_mysql_socket  # Alternative to host/port
MYSQL_POOL_LIMIT=10                # Connection pool limit

You can set these variables in your environment or use a .env file if your deployment supports it.

Usage

The MySQL MCP Server is designed to start automatically when initialized by the MCP system. Once running, you can interact with it through the MCP interface to:

List Database Tables

Query the server to retrieve a list of all available tables in the configured database.

View Table Schemas

Examine the structure of any table, including column names, data types, and constraints.

Execute SQL Queries

Run read-only SQL queries against your database. For security reasons, only SELECT statements are permitted.

Connection Management

The server handles database connections automatically using connection pooling for improved performance. The default pool limit is 10 concurrent connections, but this can be adjusted using the MYSQL_POOL_LIMIT environment variable.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "mysql" '{"command":"npx","args":["-y","mcp-server-mamp-mysql"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "mysql": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-server-mamp-mysql"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
Windows: %APPDATA%\Claude\claude_desktop_config.json
Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "mysql": {
            "command": "npx",
            "args": [
                "-y",
                "mcp-server-mamp-mysql"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
