Last week I attended the Agents Day Hackathon in Lisbon. It was a full day of talks, socializing, and building agents.

Talks

There were a few talks and a round table discussion during the hackathon. The most memorable one for me was about the challenges behind Cloudflare’s 16 MCP servers.

All 2500+ Cloudflare endpoints couldn’t fit into a single MCP server, since listing them all used up too many tokens. After a bit of back and forth they ended up with an architecture where the MCP only exposes two endpoints (search and execute), and the agents can figure out the rest.

My Project

Since this was a hackathon I of course hacked on a project of my own - Life Ops, an agent that applies the lessons of Site Reliability Engineering to real life situations. Missing a birthday or an anniversary becomes a P1 incident, with alerts, postmortems, etc. It integrated perfectly with PagerDuty, who happened to be one of the sponsors.

Demos

The project itself was a joke, but the demo I prepared resonated with the people I showed it to, including the mentors who ultimately decided who got to demo on stage. I think this was mostly because the demo wasn’t just me showing how it works, but a little skit in which I figure out that I missed my partner’s birthday and then have to handle the fallout.

Here’s a recording I made as a backup plan in case the demo gods were not on my side:

As mentioned, only five teams were picked by the five mentors, and I was lucky enough to be one of them.

The other demos were:

1. Using agents to organize your second brain.
2. Agents for classifying and valuing wines.
3. Using agents to respond to and fulfill requests in a marketplace.
4. Using agents for voice calls.

All of them a lot more serious than mine 😅

Fin

I had a fun time and I’ll be keeping an eye out for more events like this. Lisbon seems to be the place for this sort of thing right now (there’s even a Cursor Cafe in Lisbon), and it’s good to see a community forming around these new tools so that we can figure out how best to use (or not use) them together.
