Aggregate and report on logged time entries. Filter by project, client, category, date range, or billable status. Group results by project, client, date, or category.
AI agents call palace_time_summary to retrieve information from Obsidian Palace MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and organizes existing time tracking data for analysis and reporting purposes. It performs no side effects, creates no new data, and cannot alter or delete entries. The filtering and grouping are analytical operations on read data. Low severity because misuse would only affect reporting accuracy, not data integrity or external systems.
From the tool's definition Tool aggregates and reports on logged time entries with filtering and grouping capabilities. The description uses read-only operations: 'aggregate', 'report on', 'filter', 'group results'. No creation, modification, deletion, or execution is mentioned.
