-{/* MANUAL-CONTENT-START:intro */}
-The [MySQL](https://www.mysql.com/) tool enables you to connect to any MySQL database and perform a wide range of database operations directly within your agentic workflows. With secure connection handling and flexible configuration, you can easily manage and interact with your data.
-
-With the MySQL tool, you can:
-
-- **Query data**: Execute SELECT queries to retrieve data from your MySQL tables using the `mysql_query` operation.
-- **Insert records**: Add new rows to your tables with the `mysql_insert` operation by specifying the table and data to insert.
-- **Update records**: Modify existing data in your tables using the `mysql_update` operation, providing the table, new data, and WHERE conditions.
-- **Delete records**: Remove rows from your tables with the `mysql_delete` operation, specifying the table and WHERE conditions.
-- **Execute raw SQL**: Run any custom SQL command using the `mysql_execute` operation for advanced use cases.
-
-The MySQL tool is ideal for scenarios where your agents need to interact with structured data—such as automating reporting, syncing data between systems, or powering data-driven workflows. It streamlines database access, making it easy to read, write, and manage your MySQL data programmatically.
-{/* MANUAL-CONTENT-END */}

-## Usage Instructions

-{/* MANUAL-CONTENT-START:intro */}
-The [PostgreSQL](https://www.postgresql.org/) tool enables you to connect to any PostgreSQL database and perform a wide range of database operations directly within your agentic workflows. With secure connection handling and flexible configuration, you can easily manage and interact with your data.
-
-With the PostgreSQL tool, you can:
-
-- **Query data**: Execute SELECT queries to retrieve data from your PostgreSQL tables using the `postgresql_query` operation.
-- **Insert records**: Add new rows to your tables with the `postgresql_insert` operation by specifying the table and data to insert.
-- **Update records**: Modify existing data in your tables using the `postgresql_update` operation, providing the table, new data, and WHERE conditions.
-- **Delete records**: Remove rows from your tables with the `postgresql_delete` operation, specifying the table and WHERE conditions.
-- **Execute raw SQL**: Run any custom SQL command using the `postgresql_execute` operation for advanced use cases.
-
-The PostgreSQL tool is ideal for scenarios where your agents need to interact with structured data—such as automating reporting, syncing data between systems, or powering data-driven workflows. It streamlines database access, making it easy to read, write, and manage your PostgreSQL data programmatically.
