Right now, the biggest leap for AI isn’t a bigger model – it’s giving models and agents a way to act.

In this episode of Inference, I sit down with Alex Hancock – Senior Software Engineer at Block, core contributor to Goose (the open-source, multi-purpose AI agent), and a member of the Model Context Protocol (MCP) Steering Committee – to talk about the infrastructure that’s quietly powering the next wave of AI.

*We cover:*

– What MCP is – and why it’s exploding in adoption

– How it turns models from “brains in jars” into agents with arms and legs

– The MCP Steering Committee’s push for openness and real governance

– Why SDK parity, registry design, and OAuth 2.1 are make-or-break for developers

– How MCP and A2A fit together – and where they might compete

– Context discovery, context management, and why they’re the hardest problems in agentic AI

– The lessons from Goose on staying model-agnostic in a fast-moving ecosystem

– What this shift means for software development – and for the humans in the loop

Alex also shares his view on the next year of protocol development, why he thinks AGI will arrive incrementally, and how a runner’s mindset shapes his approach to building tools that last.

If you’re building agents, connecting models to the world, or just trying to understand the emerging “protocol layer” of AI, this conversation will give you a front-row seat.

Let’s find out how we’re teaching AI to act – and what’s still missing.
