There is a bug in Claude Code in GitHub Actions that requires MCP servers to be installed beforehand, delaying startup time. The optimal approach would be to install MCP servers in parallel and connect only when needed, but the MCP_TIMEOUT variable is completely ignored.

This is frustrating. Recent releases of Claude Code have also been poor quality. Unbelievable.

I've created my own issue too. And added cache workaround (10x faster) to it.
