get_aws_session_info
AI agents call get_aws_session_info 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.
The tool appears to retrieve or query AWS session metadata (credentials scope, identity, permissions). This is a Read category operation—it queries data without modifying or executing anything. Severity is low because session info retrieval alone has limited blast radius; the actual risk depends on what an attacker could do with that information, which would be a subsequent step.
From the tool's definition Tool name 'get_aws_session_info' indicates retrieval of session information; description is empty but naming convention suggests a query/fetch operation with no side effects.
