Claude Code 2.1.142: `claude agents` Gains Session Flags, Fast Mode Defaults to Opus 4.7, MCP Tool Timeout Honored

Anthropic shipped Claude Code 2.1.142 on May 14, 2026. The release adds eight session-configuration flags to `claude agents` (`--add-dir`, `--settings`, `--mcp-config`, `--plugin-dir`, `--permission-mode`, `--model`, `--effort`, `--dangerously-skip-permissions`), flips fast mode's default model from Opus 4.6 to Opus 4.7, and fixes `MCP_TOOL_TIMEOUT` not raising the per-request fetch timeout for remote HTTP/SSE MCP servers -- a regression that capped tool calls at 60 seconds regardless of configuration.
