Time tracking, invoicing, and lightweight bookkeeping for solo LLCs and freelancers. Ships with an MCP server so Claude, Cursor, or any MCP-speaking agent can start/stop timers, log time, list projects, and review entries directly — no browser tab. Available as the @squidcode/timebook npm package (stdio) and as a hosted Streamable-HTTP endpoint at https://usetimebook.com/mcp with OAuth (no install).
