list-pricing-plans
AI agents call list-pricing-plans to retrieve information from Amazon ElastiCache Memcached MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Listing pricing plans is a read-only query that retrieves publicly available or account-level pricing data without modifying, executing, or deleting anything. The blast radius if misused by an agent is minimal—it only exposes pricing information. Confidence is moderate (0.7) because the description is empty and the tool name alone must be the basis for classification, leaving room for unexpected behavior.
