MCP makes AI agents look magical. Connect a few tools, let the model call them, and suddenly your agent can search files, update records, query systems, automate workflows, and interact with real business infrastructure. But here is the problem: The more tools you add, the more expensive every request becomes. Not because the task is harder. Because the model often has to carry the entire tool catalog in context. That means: more tokens more latency more intermediate data more room for mistakes higher infrastructure cost This is fine in a demo. It gets painful in production. That is where Code Mode becomes interesting. Instead of showing the model every tool upfront, Code Mode lets the agent: discover only what it needs read compact tool interfaces orchestrate workflows through code keep unnecessary intermediate data outside the LLM context Less context. Fewer model turns. Lower cost. Cleaner architecture.…
