A Model Context Protocol server that provides MySQL database operations. This server enables AI models to interact with MySQL databases through a standardized interface.

To install MySQL Server for Claude Desktop automatically via Smithery:

npx -y @smithery/cli install @f4ww4z/mcp-mysql-server --client claude

npx @f4ww4z/mcp-mysql-server

The server requires the following environment variables to be set in your MCP settings configuration file:

recommended use

{
  "mcpServers": {
    "mysql": {
      "command": "npx",
      "args": ["-y", "@f4ww4z/mcp-mysql-server", "mysql://user:password@localhost:port/database"],
    }
  }
}

{
  "mcpServers": {
    "mysql": {
      "command": "npx",
      "args": ["-y", "@f4ww4z/mcp-mysql-server"],
      "env": {
        "MYSQL_HOST": "your_host",
        "MYSQL_USER": "your_user",
        "MYSQL_PASSWORD": "your_password",
        "MYSQL_DATABASE": "your_database"
      }
    }
  }
}

The evals package loads an mcp client that then runs the index.ts file, so there is no need to rebuild between tests. You can load environment variables by prefixing the npx command. Full documentation can be found here.
