Codex support

[takelley1]

Is support for OpenAI Codex planned? I'm unable to get it working.

MacOS Sequoia 15.6.1
Codex 0.53.0

Contents of ~/.codex/config.toml

[mcp_servers.kubernetes-mcp-server]
command = "npx"
args = ["-y", "@kubernetes-mcp-server@latest", "--read-only"]
env = {KUBECFONFIG="/Users/username/.kube/config"}

Here's the error I receive:

■ MCP client for `kubernetes-mcp-server` failed to start: handshaking with MCP server failed: connection closed: initialize response

The same configuration works correctly on Claude Code.

[manusa]

Have you tried other ways of setting it up or using the binary directly?
There's really nothing special to Codex that makes this MCP server incompatible with it.
