agent: mcp

When does this happen?

IF Using 'codex mcp' as the command argument for MCPServerStdio causes a 'Connection closed' error during initialization.

How others solved it

THEN Change the command argument from 'codex mcp' to 'codex mcp-server' when instantiating MCPServerStdio. The correct invocation is `MCPServerStdio(command='codex mcp-server', args=['...'])`.

Before: MCPServerStdio(command='codex', args=['-y', 'codex', 'mcp'])
After: MCPServerStdio(command='codex', args=['-y', 'codex', 'mcp-server'])
