I beta tested this and it’s amazing.

I asked Claude Code: find all html and accessibility errors of YouCongress via Rocket Validator’s MCP tool and fix them.

After a few runs, all green. ✅

The tool call just failed

Add MCP Server (#174) · youcongress/youcongress@0cc808c

And yes, it's based on the mcp-session-id github.com/youcongress/...

Add MCP Server (#174) · youcongress/youcongress@0cc808c

By the way, I fixed the link in the Livebook of my workshop to the YouCongress source code where I forward the MCP events: github.com/youcongress/...

If a multi-node MCP server uses StreamableHTTP/SSE, when a node receives a tool call, it needs the session of the http connection.

I solved it by forwarding to the original node, but redis or a global ETS table like you did is cleaner 🙌

But what does all this have to do with OpenRouter?

Building MCP servers for ChatGPT and API integrations Learn how to build MCP servers for use with ChatGPT connectors, deep research, or API integrations.

ChatGPT Pro and Plus too. I don’t have a pro plan anymore there but it seems it should still work. By the way, I remember their UX when using MCP worse platform.openai.com/docs/mcp

It’s great it stopped snowing and you came! Actually, in the morning I feared that we may need to cancel the whole event. Good to see you there!

This Wednesday, I’ll be teaching a workshop on LLMs, Agents, and MCP in Elixir.

We are fully booked! 🚫🪑

However, if you want me to send you the Livebook notebook with all the content afterwards, just drop a comment or DM me.

Why the AGI race may be bigger near-term existential risk than misalignment A Fermi-paradox metaphor for coordination failure

The biggest near-term risk from AI isn’t “evil superintelligence.”

It’s a coordination failure.

I expand on why this matters using the Fermi Paradox as a metaphor:

Just tried asking Claude (desktop) to create a simple Livebook tool for me, and it worked!

Once done, I can click "Open in Livebook" and it opens directly in my Livebook desktop 🎉

Human testimony in the age of AI Why public decisions need sourced quotes, not just AI answers

Most AIs compress disagreement into one answer.
Governance needs the opposite: sourced quotes, stance-labeled (For / Abstain / Against), linked to primary sources.

The Perpetual Technological Cage Unless superintelligence is developed under a global consensus, the risks will be shared by all, but the upside won't. This is why I signed the superintelligence statement.

I signed the "superintelligence statement". Yet, beyond "flourish or doom", there’s a quieter risk:

If the US/China build it now, they'll enforce a "non-proliferation" to keep it that way.

That’s how a Perpetual Technological Cage begins for the rest of us:

We’ve removed AI-generated perspectives. All expert and public-figure stances on YouCongress now come from verifiable, sourced quotes—so you can delegate with confidence.

We are still looking for a second speaker for the Global Elixir Meetups event in Madrid.
