## DBHub — AI Meets Your Database

### Supported Databases

| Database | Status |
|----------|--------|
| PostgreSQL | ✅ |
| MySQL | ✅ |
| MariaDB | ✅ |
| SQL Server | ✅ |
| SQLite | ✅ |

### Why Only Two Tools?

Most database MCP servers expose dozens of tools, consuming precious context window tokens. DBHub takes a minimalist approach with just two tools, maximizing the space available for your actual queries and results.

### Safety Features

- **Read-only mode** — Prevent accidental writes
- **Row limiting** — Cap result set sizes
- **Query timeout** — Prevent runaway queries
- **SSL/TLS** — Encrypted connections
- **SSH tunneling** — Secure access to remote databases

### Installation Options

```bash
# NPX (recommended)
npx @bytebase/dbhub --transport http --port 8080 --dsn "postgres://..."

# Docker
docker run --rm --init --name dbhub \
  --publish 8080:8080 bytebase/dbhub \
  --transport http --port 8080 --dsn "postgres://..."

# Multi-database via TOML config
npx @bytebase/dbhub --transport http --port 8080 --config databases.toml
```

### Multi-Database Config
