{
  "mcpServers": {
    "mysql": {
      "command": "/path/to/mysql-server/build/index.js",
      "env": {
        "MYSQL_HOST": "your-mysql-host",
        "MYSQL_USER": "your-mysql-user",
        "MYSQL_PASSWORD": "your-mysql-password",
        "MYSQL_DATABASE": "your-mysql-database"

Debugging

Since the MCP server communicates via stdio, debugging can be challenging. We recommend using MCP Inspector, which is available as a package script:

npm run inspector

The Inspector will provide a URL to access the debugging tools in the browser.
