New CLAUDE_CODE_MCP_CONNECTOR_PREWAIT_MS environment variable overrides how long Claude Code waits for remote MCP servers to start
Claude Code can connect to MCP servers (external tool providers using the Model Context Protocol). Before starting a session, it may wait briefly for remote MCP servers to become ready. That wait behavior is now controlled by a new environment variable, CLAUDE_CODE_MCP_CONNECTOR_PREWAIT_MS, which can set an explicit deadline and a local-only override. This replaces a simpler check that only looked at whether CLAUDE_CODE_ENVIRONMENT_KIND was set to "bridge".
This gives more direct control over MCP startup timing than the previous environment-kind check allowed, which is useful for tuning how long Claude Code waits on remote MCP servers before a session begins.
