Along the same lines, I've just done a build called Jeeves. A bit less flair, but very fast to put together. The stack is:

1. Claude Desktop 2. Projects 3. MCPs for [Notion, Todoist] and exploring emails + WhatsApp for a next upgrade

This is for me to support productivity workflows for consulting + a startup. There are a few Notion databases - clients, projects, meetings, plus a Jeeves database. The Jeeves database is up to Jeeves how it uses it, but with some guidance. Jeeves uses his own database for things like tracking a migration of all of my previous meeting notes etc under the new structure.

So my databases, I've set up my best practices for use. Here's how my minutes look, here's how client one pagers looks like, here's the information to connect it all together, and here's how I manage To Dos. I then drop in transcriptions into a new chat, with some text-expanding prompts in Alfred for a few common meetings or similar, and away he goes. He'll turn the transcript into meeting notes, create the todos, check everything with me, do a pass, and then go and file everything away into Notion and Todoist via MCP.

It's also self documenting on this. The todoist MCP had some bugs, so I instructed Jeeves to go, run all the various use cases it could, figure out the limitations and strengths, document it, and it's filed away in the Jeeves database that it can pull into context.

It lacks the cron features which I would like, but honestly, a once-a-day prepared prompt dropping into Claude is hardly difficult.
