Get all items from the inbox/capture list
AI agents call getInbox to retrieve information from Knowledge MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns data from an inbox/capture list without creating, modifying, deleting, or executing any operations. It is a pure read operation with minimal security impact—the worst-case scenario is exposure of the user's task/note data already stored in their own repository.
From the tool's definition Tool name 'getInbox' and description 'Get all items from the inbox/capture list' indicate a retrieval operation with no modification, deletion, or execution of external code.
