Understand this story
Claude Code released version v2.1.319, adding support for MCP tasks in the terminal: when an MCP server executes tool calls as tasks, Claude Code immediately moves to the background and notifies Claude upon completion; a new CLAUDE_CODE_DISABLE_MCP_TASK_BACKGROUND environment variable was also added to control this behavior. This version also adjusts the behavior of auto mode when telemetry or feature toggles are disabled: calls that the server cannot check will be prompted or denied, no longer falling back to the built-in classifier, and CLAUDE_CODE_AUTO_MODE_SERVER=0 can be used to retain the original behavior. In addition, a permissions.denyInsteadOfPrompting setting and a /claude-api latency-optimize command were added, and issues such as MCP legacy handshake connection failures and blank /diff output were fixed. There are currently no further developments.

Claude Code v2.1.319 Released: Adjusts auto mode gateway behavior and adds background support for MCP tasks
Claude Code v2.1.319 adjusts the behavior of auto mode when telemetry or feature toggles are disabled: calls that the server cannot check will be prompted or denied, no longer falling back to the built-in classifier; the original behavior can be maintained with CLAUDE_CODE_AUTO_MODE_SERVER=0. The new version supports MCP tasks in the terminal; when an MCP server executes tool calls as tasks, Claude Code immediately moves to the background and notifies Claude upon completion, and a new CLAUDE_CODE_DISABLE_MCP_TASK_BACKGROUND environment variable has been added to control this behavior. In addition, a new permissions.denyInsteadOfPrompting setting and the /claude-api latency-optimize command have been added, and multiple issues have been fixed, including MCP legacy handshake connection failures and blank /diff output.
