## About
[Cloud SQL for MySQL][csql-mysql-docs] is a fully-managed database service
that helps you set up, maintain, manage, and administer your MySQL
relational databases on Google Cloud Platform.
If you are new to Cloud SQL for MySQL, you can try [creating and connecting
to a database by following these instructions][csql-mysql-quickstart].
[csql-mysql-docs]: https://cloud.google.com/sql/docs/mysql
[csql-mysql-quickstart]: https://cloud.google.com/sql/docs/mysql/connect-instance-local-computer
## Available Tools
- [`mysql-sql`](../tools/mysql/mysql-sql.md)
Execute pre-defined prepared SQL queries in Cloud SQL for MySQL.
- [`mysql-execute-sql`](../tools/mysql/mysql-execute-sql.md)
Run parameterized SQL queries in Cloud SQL for MySQL.
- [`mysql-list-active-queries`](../tools/mysql/mysql-list-active-queries.md)
List active queries in Cloud SQL for MySQL.
- [`mysql-list-tables`](../tools/mysql/mysql-list-tables.md)
List tables in a Cloud SQL for MySQL database.
- [`mysql-list-tables-missing-unique-indexes`](../tools/mysql/mysql-list-tables-missing-unique-indexes.md)
List tables in a Cloud SQL for MySQL database that do not have primary or unique indices.
- [`mysql-list-table-fragmentation`](../tools/mysql/mysql-list-table-fragmentation.md)
List table fragmentation in Cloud SQL for MySQL tables.
### Pre-built Configurations
- [Cloud SQL for MySQL using
MCP](https://googleapis.github.io/genai-toolbox/how-to/connect-ide/cloud_sql_mysql_mcp/)
Connect your IDE to Cloud SQL for MySQL using Toolbox.
## Requirements
### IAM Permissions
By default, this source uses the [Cloud SQL Go Connector][csql-go-conn] to
authorize and establish mTLS connections to your Cloud SQL instance. The Go
connector uses your [Application Default Credentials (ADC)][adc] to authorize
your connection to Cloud SQL.
In addition to [setting the ADC for your server][set-adc], you need to ensure
the IAM identity has been given the following IAM roles (or corresponding
permissions):
- `roles/cloudsql.client`
{{< notice tip >}}
If you are connecting from Compute Engine, make sure your VM
also has the [proper
scope](https://cloud.google.com/compute/docs/access/service-accounts#accesscopesiam)
to connect using the Cloud SQL Admin API.

[set-adc]: https://cloud.google.com/docs/authentication/provide-credentials-adc
### Networking
Cloud SQL supports connecting over both from external networks via the internet
([public IP][public-ip]), and internal networks ([private IP][private-ip]).
For more information on choosing between the two options, see the Cloud SQL page
[Connection overview][conn-overview].
You can configure the `ipType` parameter in your source configuration to
`public` or `private` to match your cluster's configuration. Regardless of which
you choose, all connections use IAM-based authorization and are encrypted with
mTLS.
[private-ip]: https://cloud.google.com/sql/docs/mysql/configure-private-ip
[public-ip]: https://cloud.google.com/sql/docs/mysql/configure-ip
[conn-overview]: https://cloud.google.com/sql/docs/mysql/connect-overview
### Database User
Currently, this source only uses standard authentication. You will need to [create
a MySQL user][cloud-sql-users] to login to the database with.
[cloud-sql-users]: https://cloud.google.com/sql/docs/mysql/create-manage-users
## Example
```yaml
sources:
my-cloud-sql-mysql-source:
kind: cloud-sql-mysql
project: my-project-id
region: us-central1
instance: my-instance
database: my_db
user: ${USER_NAME}
password: ${PASSWORD}
# ipType: "private"
```
{{< notice tip >}}
Use environment variable replacement with the format ${ENV_NAME}
instead of hardcoding your secrets into the configuration file.
