Works still?

[shtirlitsDva]

Hello, does this works still? I am trying this out because I experience that OAI own Codex MCP times out a lot.

The ping command runs ok, but no other command from Claude Code. I also tried it manually:
npx -y codex-mcp-server
codex-mcp-server started successfully
{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"codex","arguments":{"prompt":"What is 2+2?"}}}
Executing: codex exec --model gpt-5.2-codex --skip-git-repo-check What is 2+2?
{"result":{"content":[{"type":"text","text":"Error in tool "codex": Failed to execute tool "codex": Failed to execute codex command"}],"isError":true},"jsonrpc":"2.0","id":1}

I know this is rather slim in information on the bug, but I will be happy to provide more information.

@shtirlitsDva it looks to me there is an issue with your local codex binary, could you upgrade or reinstall? Here is my testing result:

echo '{"jsonrpc":"2.0","id":3,"method":"tools/call","params":{"name":"codex","arguments":{"prompt":"What is 2+2?"}}}' | npx -y codex-mcp-server

codex-mcp-server started successfully
Executing: codex exec --model gpt-5.2-codex --skip-git-repo-check What is 2+2?
