Codex Desktop for Windows does not load local MCP plugin tools

I submitted in-app feedback with uploaded thread:

019dbc78-7907-7dc3-a498-8255e105f63c

Summary:
Codex Desktop for Windows does not expose tools from a local MCP plugin even though the plugin is registered, enabled, cached, and the MCP server works when run directly.

Expected:
After installing/enabling a local MCP plugin and restarting Codex Desktop, tools from that plugin should be available to Codex.

Actual:
Tool discovery returns 0 tools for the local plugin, and no tools from the plugin are registered after both app restart and full computer restart.

Validation:
The plugin's MCP server responds successfully to initialize and tools/list when run directly from the plugin root.
