MCP on Code Mode

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.
