## Components

### Tools

The server provides two tools:

  - `database` parameter: Name of the database to connect to (string)
  - Returns a confirmation message when connection is successful

- `execute_query`: Executes MySQL queries
  - `query` parameter: SQL query/queries to execute (string)
  - Returns query results in JSON format
  - Multiple queries can be sent separated by semicolons

## Configuration

The server uses the following environment variables:

- `MYSQL_HOST`: MySQL server address (default: "localhost")
- `MYSQL_USER`: MySQL username (default: "root") 
- `MYSQL_PASSWORD`: MySQL password (default: "")
- `MYSQL_DATABASE`: Initial database (optional)
- `MYSQL_READONLY`: Read-only mode (set to 1/true to enable, default: false)

### Installing via Smithery

To install MySQL Database Integration Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@burakdirin/mysqldb-mcp-server):

```bash
npx -y @smithery/cli install @burakdirin/mysqldb-mcp-server --client claude
```

## Development

### Building and Publishing

To prepare the package for distribution:

1. Sync dependencies and update lockfile:
```bash
uv sync
```

2. Build package distributions:
```bash
uv build
```

This will create source and wheel distributions in the `dist/` directory.

3. Publish to PyPI:
```bash
uv publish
```

Note: You'll need to set PyPI credentials via environment variables or command flags:
- Token: `--token` or `UV_PUBLISH_TOKEN`
- Or username/password: `--username`/`UV_PUBLISH_USERNAME` and `--password`/`UV_PUBLISH_PASSWORD`

### Debugging

Since MCP servers run over stdio, debugging can be challenging. For the best debugging
experience, we strongly recommend using the [MCP Inspector](https://github.com/modelcontextprotocol/inspector).

You can launch the MCP Inspector via [`npm`](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm) with this command:

```bash
npx @modelcontextprotocol/inspector uv --directory /Users/burakdirin/Projects/mysqldb-mcp-server run mysqldb-mcp-server
```

Upon launching, the Inspector will display a URL that you can access in your browser to begin debugging.
