The AI SDK streamText() defaults stepMs to 120s, which covers the entire step including tool execution. This caused MCP tool calls to timeout at 120s even when experimental.mcp_timeout was configured to a much larger value, because the AI SDK step timeout fired before the MCP-level timeout.

What does this PR do?
MCP tool calls timeout at 120s regardless of
experimental.mcp_timeoutconfig.The AI SDK
streamText()has astepMsparam (default 120s) that covers the entire step — LLM call + tool execution. OpenCode correctly passesmcp_timeoutto MCP SDK'scallTool(), but never setsstepMsonstreamText(). So the AI SDK's 120s default fires before the MCP-level timeout is ever reached.Fix: pass
experimental.mcp_timeoutasstepMstostreamText(), so the AI SDK step timeout aligns with the MCP timeout. Whenmcp_timeoutis not configured, behavior is unchanged (AI SDK default applies).How did you verify your code works?
