AI agents call read_multiple_notes to retrieve information from MCP Notes without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries data from multiple note files with no side effects. It performs a read-only operation that does not create, modify, delete, or execute any external operations. The plural form reinforces it is a batch read operation rather than any other action category.
From the tool's definition Tool name 'read_multiple_notes' and description 'Read the contents of multiple note files simultaneously' explicitly indicate retrieval without modification.
