BizDesk MCP: a custom MCP

BizDesk MCP: a custom MCP server that lets Claude handle the money side of a small service business: clients, quotes, invoices, payments and overdue reminders. 21 tools, including an overdue report, payment reminder drafts, quote to invoice and PDF export. Built in Python with the official MCP SDK and SQLite, with money kept in exact cents. Reminders are drafts only, so Claude never emails anyone on its own. 49 automated tests. Open source on my GitHub. The images show real Claude sessions using the server and the PDF it exported, with fictional demo data.
