English

A Model Context Protocol (MCP) server for MySQL and MariaDB — designed for AI coding assistants like Claude Code, Cursor, Windsurf, GitHub Copilot, and any MCP-compatible client.

One server, many databases. Connect multiple MySQL and MariaDB databases through a single MCP server with built-in SQL injection protection, read-only mode, connection pooling, and hot-reload configuration.

Why Use This?

  • AI-native database access — let Claude, Cursor, or Copilot query your MySQL databases directly

  • Multi-database — manage all your MySQL connections from one MCP server

  • Secure by default — state-machine SQL injection parser, read-only transactions, prepared statements

  • Hot-reload config — change connections without restarting the server

  • Per-project isolation — use --label to expose only relevant databases

  • 7 powerful tools — query, describe, explain, health check and more

  • Broad compatibility — MySQL 5.7–9.x, MariaDB 10.x–11.x, AWS RDS, Azure, GCP, PlanetScale

Tools

Tool

Description

Quick Start

Install

git clone https://github.com/VKirill/multi-mysql-mcp-server.git
cd multi-mysql-mcp-server
npm install
npm run build

Configure

Create ~/.mcp-mysql/config.json (or use --config to specify a custom path):

{
  "connections": [
    {
      "label": "local",
      "host": "localhost",
      "port": 3306,
      "user": "dev",
      "password": "devpass123",
      "database": "myapp"
    },
    {
      "label": "production",
      "url": "mysql://${PROD_USER}:${PROD_PASS}@db.example.com:3306/prod_db",
      "readOnly": true,
      "ssl": true
    }
  ]
}

Add to Claude Code

claude mcp add mysql -- node /path/to/dist/index.js --config ~/.mcp-mysql/config.json

Or add to ~/.claude.json:

{
  "mcpServers": {
    "mysql": {
      "type": "stdio",
      "command": "node",
      "args": ["/path/to/dist/index.js", "--config", "/path/to/config.json"]
    }
  }
}

Add to Cursor

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "mysql": {
      "command": "node",
      "args": ["/path/to/dist/index.js", "--config", "/path/to/config.json"]
    }
  }
}

Docker

docker build -t mcp-mysql .
docker run -v /path/to/config.json:/app/config.json mcp-mysql --config /app/config.json

--label <name>

Security

  • SQL injection protection — state-machine parser detects multi-statement queries, handles MySQL-specific syntax (backtick identifiers, # comments, backslash escapes)

  • DDL protection — blocks CREATE, DROP, ALTER, TRUNCATE statements

  • Prepared statements — all user parameters go through connection.execute() with ? placeholders

  • Read-only by defaultSET SESSION TRANSACTION READ ONLY wraps all queries in transactions

  • EXPLAIN safety — EXPLAIN ANALYZE always wrapped in transaction with ROLLBACK

  • Config permissions — warns if config file is world-readable on Unix

  • Zod validation — config file validated with strict schemas

See SECURITY.md for the full security model and responsible disclosure policy.

Compatibility

  • MySQL 5.7, 8.0, 8.4, 9.x

  • MariaDB 10.x, 11.x

  • Cloud: AWS RDS, Azure Database for MySQL, Google Cloud SQL, PlanetScale, Aiven

  • Node.js >= 18

  • MCP clients: Claude Code, Cursor, Windsurf, GitHub Copilot, VS Code, any MCP-compatible tool


Related MCP server: MySQL MCP Server

Русский

MCP-сервер для MySQL и MariaDB — предназначен для AI-ассистентов: Claude Code, Cursor, Windsurf, GitHub Copilot и любых MCP-совместимых клиентов.

Один сервер — много баз данных. Подключайте несколько MySQL и MariaDB баз через один MCP-сервер со встроенной защитой от SQL-инъекций, режимом read-only, пулом соединений и горячей перезагрузкой конфигурации.

Преимущества

  • AI-нативный доступ к БД — Claude, Cursor или Copilot напрямую запрашивают ваши MySQL базы

  • Мульти-база — все MySQL-подключения в одном MCP-сервере

  • Безопасность по умолчанию — state-machine парсер SQL-инъекций, read-only транзакции, prepared statements
