# mariadb-mcp-server

MCP (Model Context Protocol) server for MariaDB/MySQL databases. Provides AI assistants with safe, controlled database access through per-connection read/write permissions.

## Features

- **Multi-connection** — manage multiple MariaDB/MySQL databases from a single server
- **Per-connection access control** — `read` and `write` flags per connection
- **Optional limits** — `statement_timeout_ms`, `default_row_limit`, `max_row_limit` (all optional, unlimited by default)
- **SQL guard** — validates queries to prevent accidental writes through read tools
- **Transaction support** — atomic multi-query execution on writable connections

## Installation

```bash
npm install -g @cemalturkcann/mariadb-mcp-server
```

Or use directly with npx:

```bash
npx @cemalturkcann/mariadb-mcp-server
