search_transaction_spans
AI agents call search_transaction_spans to retrieve information from AWS Application Signals MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Searching transaction spans is a read-only operation that retrieves trace data for monitoring and debugging without modifying any state or executing external code. It falls squarely into the 'Read' category. Confidence is slightly reduced due to empty tool description, but the server context and naming strongly indicate a query/retrieval function rather than modification or execution.
From the tool's definition Tool name 'search_transaction_spans' and server context indicate querying distributed tracing data from AWS X-Ray for troubleshooting purposes.
