+
+## 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
+
+{{< list-tools dirs="/integrations/mysql/tools" >}}
+
+
+### Pre-built Configurations
+
+- [Cloud SQL for MySQL using
+  MCP](https://mcp-toolbox.dev/documentation/connect-to/ides/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.
+{{< /notice >}}
+
+[csql-go-conn]: https://github.com/GoogleCloudPlatform/cloud-sql-go-connector
+[adc]: https://cloud.google.com/docs/authentication#adc
+[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
+
+### Authentication
+
+This source supports both password-based authentication and IAM
+authentication (using your [Application Default Credentials][adc]).
+
+#### Standard Authentication
+
+To connect using user/password, [create
+a MySQL user][cloud-sql-users] and input your credentials in the `user` and
+`password` fields.
+
+```yaml
+user: ${USER_NAME}
+password: ${PASSWORD}
+```
+
+[cloud-sql-users]: https://cloud.google.com/sql/docs/mysql/create-manage-users
+
+#### IAM Authentication
+
+To connect using IAM authentication:
+
+1. Prepare your database instance and user following this [guide][iam-guide].
+2. You could choose one of the two ways to log in:
+    - Specify your IAM email as the `user`.
+    - Leave your `user` field blank. Toolbox will fetch the [ADC][adc]
+      automatically and log in using the email associated with it.
+
+3. Leave the `password` field blank.
+
+[iam-guide]: https://cloud.google.com/sql/docs/mysql/iam-logins
+[cloudsql-users]: https://cloud.google.com/sql/docs/mysql/create-manage-users
+
+
+## Example
+
+```yaml
+kind: source
+name: my-cloud-sql-mysql-source
+type: 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.
