Open-source coding agent OpenCode 2.0 adds 'Code Mode' that turns MCP tools into script functions, plus background agents (community report)

Verified (fact)

According to a GeekNews summary, OpenCode 2.0 has moved to an architecture that automatically runs a single background service. The TUI, web interface, and desktop app all connect to the same central process. The new 'Code Mode' converts MCP servers and OpenAPI endpoints into functions that can be called from scripts, handling tasks that combine multiple tools. Background agents were also introduced.

Why it matters (interpretation)

The 'Code Mode' approach, which bundles tool calls into code instead of making them one at a time, is now reaching open-source coding agents and could change the efficiency of tasks that chain multiple MCP tools.
