Fetch real-time AWS RDS database pricing. Returns 353 instance types across multiple database engines.
AI agents call refresh_aws_rds_pricing to retrieve information from Cloud Cost MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves pricing information from AWS RDS without modifying, deleting, or executing any operations. It has no side effects beyond reading current pricing data. The blast radius of misuse is minimal—an agent could only retrieve pricing information, which is typically public or low-sensitivity data. Classification as Read is appropriate.
From the tool's definition Tool description states it 'Fetch[es] real-time AWS RDS database pricing' and 'Returns 353 instance types'. The verb 'fetch' and 'returns' indicate data retrieval with no modification or execution of external operations.
