## Summary

Philipp Schmid argues agents may soon need only one tool, as they move from a few tools to dynamic tool search and then to Code Mode. He wrote a guide on how Code Mode works, why a typed JavaScript or Python sandbox can beat raw bash, and why he expects MCP to regain strength in 2027. The post includes a minimal example using Gemini 4 Argon and recommends the pi tool for testing it.

Are Agents soon going to have only 1 tool? We went from a handful of tools, to dynamic tool search, and now to collapsing everything into code mode. 

Wrote down how Code Mode works, why a typed JS/Python sandbox can beat raw bash, and why MCP is going to go back strong in 2027.  With an a minimal example for Gemini 4 Argon.

If you plan to explore code mode i can recommend testing with pi! Easily hackable and comes with strong foundation.
