Timesheet Data MCP

MCP server that provides work checkpoint querying and timesheet report storage for AI assistants. Part of a personal AI-powered time tracking system — reads checkpoints logged via the Work Checkpoints Raycast extension and stores finalized timesheet reports in a local SQLite database.
