MCP on Code Mode (Interview)

MCP on Code Mode (Interview)

Author: Changelog Media May 16, 2026 Duration: 1:54:52
This week I'm talking with Matt Carey about Code Mode and how most of us have been thinking about MCP all wrong. Matt works on the Agents SDK and MCP at Cloudflare — we discuss how server-side Code Mode lets one MCP server expose all ~2,500 Cloudflare API endpoints in about 1,000 tokens of context, the dynamic Worker loader that runs model-written code safely in a V8 isolate, Matt's own workflow with Claude, where memory fits into the future of agents, and his Zaggy git wrapper that keeps agents from force-pushing his repos.

Each week, the team at Changelog Media sifts through the noise of the software world to bring you a thoughtful mix of news, analysis, and conversation. The Changelog: Software Development, Open Source is more than a weekly brief; it’s a long-form dialogue with the developers, maintainers, and thinkers who are shaping the future of technology. You’ll hear in-depth technical interviews that go beyond surface-level takes, exploring the real challenges and triumphs behind significant open source projects and industry trends. The discussion is grounded in the daily reality of building software, making the content immediately relevant whether you’re a seasoned engineer or deeply curious about the craft. This podcast operates with the belief that open source is more than code-it’s about the people and the communities that sustain it. By tuning in, you join a conversation that values depth over hot takes and substance over speed, all while keeping a pulse on the weekly developments that matter. It’s a consistent source for anyone who wants to understand not just what is changing in software development, but why it matters and how it all fits together.
