create-serverless-cache

// WHEN AI AGENTS USE THIS TOOL

AI agents use create-serverless-cache to create or modify resources in AWS ElastiCache MCP Server. Write operations carry medium risk because an autonomous agent could trigger bulk unintended modifications. Rate limits prevent a single agent session from making hundreds of changes in rapid succession. Argument validation ensures the agent passes expected values.

// WHY ENFORCE A POLICY ON CREATE-SERVERLESS-CACHE

Without a policy, an AI agent could call create-serverless-cache repeatedly, creating or modifying resources faster than any human could review. Intercept's rate limiting ensures write operations happen at a controlled pace, and argument validation catches malformed or unexpected inputs before they reach AWS ElastiCache MCP Server.

// RECOMMENDED POLICY

Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

What does the create-serverless-cache tool do? +

Create a new Amazon ElastiCache serverless cache. This tool creates a new serverless cache with specified configuration including: - Serverless cache name and capacity - Optional VPC and security settings - Optional encryption settings - Optional snapshot restoration and backup settings - Optional usage limits and user groups - Optional tags Parameters: serverless_cache_name (str): Name of the serverless cache. engine (str): Cache engine type. description (Optional[str]): Description for the cache. kms_key_id (Optional[str]): KMS key ID for encryption. major_engine_version (Optional[str]): Major engine version. snapshot_arns_to_restore (Optional[List[str]]): List of snapshot ARNs to restore from. subnet_ids (Optional[List[str]]): List of subnet IDs for VPC configuration. tags (Optional[Union[str, List[Dict[str, Optional[str]]], Dict[str, Optional[str]]]]): Tags to apply to the cache. Tag requirements: - Key: (string) Required. The key for the tag. Must not be empty. - Value: (string) Optional. The tag's value. May be null. Supports three formats: 1. Shorthand syntax: "Key=value,Key2=value2" or "Key=,Key2=" for null values 2. Dictionary: {"key": "value", "key2": null} 3. JSON array: [{"Key": "string", "Value": "string"}, {"Key": "string2", "Value": null}] Can be None if no tags are needed. security_group_ids (Optional[List[str]]): List of security group IDs. cache_usage_limits (Optional[CacheUsageLimits]): Usage limits for the cache. Structure: { "DataStorage": { "Maximum": int, # Maximum storage in GB "Minimum": int, # Minimum storage in GB "Unit": "GB" # Storage unit (currently only GB is supported) }, "ECPUPerSecond": { "Maximum": int, # Maximum ECPU per second "Minimum": int # Minimum ECPU per second } } user_group_id (Optional[str]): ID of the user group to associate with the cache. snapshot_retention_limit (Optional[int]): Number of days for which ElastiCache retains automatic snapshots. daily_snapshot_time (Optional[str]): Time range (in UTC) when daily snapshots are taken (e.g., '04:00-05:00'). Returns: Dict containing information about the created serverless cache.. It is categorised as a Write tool in the AWS ElastiCache MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create-serverless-cache? +

Add a rule in your Intercept YAML policy under the tools section for create-serverless-cache. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the AWS ElastiCache MCP Server MCP server.

What risk level is create-serverless-cache? +

create-serverless-cache is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create-serverless-cache? +

Yes. Add a rate_limit block to the create-serverless-cache rule in your Intercept policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create-serverless-cache completely? +

Set action: deny in the Intercept policy for create-serverless-cache. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create-serverless-cache? +

create-serverless-cache is provided by the AWS ElastiCache MCP Server MCP server (awslabs.elasticache-mcp-server). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
