Claude Code 2.1.319 adds MCP task background execution in terminal

code.claude.comagent

MCP server tool calls now run in the background immediately in terminal sessions, with results reported when they complete. This improves workflow responsiveness for long-running operations. A new CLAUDE_CODE_DISABLE_MCP_TASK_BACKGROUND environment variable lets you revert to waiting for MCP tasks inline if needed.
