AI agents use modify-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.
Without a policy, an AI agent could call modify-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.
Write tools can modify data. A rate limit prevents runaway bulk operations from AI agents.

Modify an Amazon ElastiCache serverless cache. This tool modifies the configuration of an existing serverless cache including: - Cache description - Engine version - Snapshot settings - Usage limits - Security groups - User groups Parameters: serverless_cache_name (str): Name of the serverless cache to modify. apply_immediately (Optional[bool]): Whether to apply changes immediately or during maintenance window. description (Optional[str]): New description for the cache. major_engine_version (Optional[str]): New major engine version. 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'). cache_usage_limits (Optional[CacheUsageLimits]): New 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 } } security_group_ids (Optional[List[str]]): List of security group IDs. user_group_id (Optional[str]): ID of the user group to associate with the cache. Returns: Dict containing information about the modified 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.
Add a rule in your Intercept YAML policy under the tools section for modify-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.
modify-serverless-cache is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the modify-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.
Set action: deny in the Intercept policy for modify-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.
modify-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.
