MCP server that lets Claude query your Google Calendar
Basic Google Calendar MCP wrapper when dozens of similar calendar tools already exist.

The UI maps common operators to form fields (site:, inurl:, intitle:, filetype:, after:/before:) and can parse an existing query back into the builder — handy when you inherit someone else's search. It's intentionally tiny and easy to self-host, but it's more a useful utility than a novel product since browser extensions and similar generators already cover this space.

The side-by-side visual builder and live SQL editor is the real payoff — drag tables onto a canvas, draw joins, and watch the SQL and results update so JOINs actually click. It's not a novel database, but shipping an in-browser SQL sandbox with a downloadable client, sample e‑commerce dataset, and no-signup access makes this a very effective, demo-friendly way to learn tricky SQL concepts.
Handwritten parser for clarity teaches query engine internals with working Rust code.
