[Feature Request] Initialization timeout cannot be modified

`MCP` server initialization cannot be set via `cli` argument or env var.

see:

This cause issue when the `MCP` server requires an external auth that can take more than 10 seconds.

This is also an issue when the `MCP` server is downloaded on the fly and crash for the first interaction because the download takes more than 10 seconds. In this situation, it can be fixed by calling the `MCP` servers a second time after the first timeout or pre-downloading it.

Thank you for this amazing tool.
