Tool: create_resource

Create an AWS resource.

Parameters: resource_type: The AWS resource type (e.g., "AWS::S3::Bucket") properties: A dictionary of properties for the resource region: AWS region to use (e.g., "us-east-1", "us-west-2")

Returns: Information about the created resource with a consistent structure: { "status": Status of the operation ("SUCCESS", "PENDING", "FAILED", etc.) "resource_type": The AWS resource type "identifier": The resource identifier "is_complete": Boolean indicating whether the operation is complete "status_message": Human-readable message describing the result "request_token": A token that allows you to track long running operations via the get_resource_request_status tool "resource_info": Optional information about the resource properties }

Parameters	Type	Description
properties	object	A dictionary of properties for the resource
resource_type	string	The AWS resource type (e.g., "AWS::S3::Bucket", "AWS::RDS::DBInstance")
region	string optional	The AWS region that the operation should be performed in

Tool: create_template

Create a CloudFormation template from existing resources using the IaC Generator API.

This tool allows you to generate CloudFormation templates from existing AWS resources that are not already managed by CloudFormation. The template generation process is asynchronous, so you can check the status of the process and retrieve the template once it's complete. You can pass up to 500 resources at a time.

Examples:

1. Start template generation for an S3 bucket: create_template( template_name="my-template", resources=[{"ResourceType": "AWS::S3::Bucket", "ResourceIdentifier": {"BucketName": "my-bucket"}}], deletion_policy="RETAIN", update_replace_policy="RETAIN" )

2. Check status of template generation: create_template(template_id="arn:aws:cloudformation:us-east-1:123456789012:generatedtemplate/abcdef12-3456-7890-abcd-ef1234567890")

3. Retrieve and save generated template: create_template( template_id="arn:aws:cloudformation:us-east-1:123456789012:generatedtemplate/abcdef12-3456-7890-abcd-ef1234567890", save_to_file="/path/to/template.yaml", output_format="YAML" ) Parameters|Type|Description -|-|- deletion_policy|string optional|Default DeletionPolicy for resources in the template (RETAIN, DELETE, or SNAPSHOT) output_format|string optional|Output format for the template (JSON or YAML) region|string optional|The AWS region that the operation should be performed in resources|string optional|List of resources to include in the template, each with 'ResourceType' and 'ResourceIdentifier' save_to_file|string optional|Path to save the generated template to a file template_id|string optional|ID of an existing template generation process to check status or retrieve template template_name|string optional|Name for the generated template update_replace_policy|string optional|Default UpdateReplacePolicy for resources in the template (RETAIN, DELETE, or SNAPSHOT)

Tool: delete_resource

Delete an AWS resource.

Parameters: resource_type: The AWS resource type (e.g., "AWS::S3::Bucket") identifier: The primary identifier of the resource to delete (e.g., bucket name for S3 buckets) region: AWS region to use (e.g., "us-east-1", "us-west-2")

Returns: Information about the deletion operation with a consistent structure: { "status": Status of the operation ("SUCCESS", "PENDING", "FAILED", "NOT_FOUND", etc.) "resource_type": The AWS resource type "identifier": The resource identifier "is_complete": Boolean indicating whether the operation is complete "status_message": Human-readable message describing the result "request_token": A token that allows you to track long running operations via the get_resource_request_status tool }

Parameters	Type	Description
identifier	string	The primary identifier of the resource to get (e.g., bucket name for S3 buckets)
resource_type	string	The AWS resource type (e.g., "AWS::S3::Bucket", "AWS::RDS::DBInstance")
region	string optional	The AWS region that the operation should be performed in…
