Elicitation support

[theg1239]

What variant of Codex are you using?

CLI 0.107.0

What feature would you like to see?

When using MCP servers that require per-tool approval via form elicitation, Codex currently cannot complete the tool call. It would be good to have the Codex MCP client support tool approval via elicitation.

• Codex mcp-server can hang indefinitely when command approval requires elicitation but MCP client cannot answer #11816

This does not seem like a duplicate of #11816.

#11816 is a server-side bug in codex mcp-server: when approval requires elicitation and the client never answers, the server can hang indefinitely.

This issue is different. In my case there was no hang. The MCP server returned a clear error immediately:

This MCP server requires a client with form elicitation support so each tool call can be explicitly approved.

So the server behaved correctly. The missing piece is client-side support, the Codex MCP client currently does not implement the MCPcorm elicitation flow needed to surface the approval UI and send the user’s response back to the server.

That makes this a feature request for Codex clients to support MCP form elicitation, not a report about the indefinite-hang bug in #11816.

I'd also like to see this. My understanding is this is a blocker to using GitHub MCP remotely via OAuth github/github-mcp-server#132

The ask for GitHub MCP is URL Elicitation, not form mode however, as we are hoping to improve security by providing STDIO Oauth and we want to provide the interactive oauth login via secure URL Elicitation.

We have a fallback of form Elicitation for the device code if interactive oauth fails, but the strong desire is for MCP clients generally to support Elicitation fully.

@etraut-openai does OAI require issue upvotes to implement standard parts of the MCP spec?

[Kludex]

Can we reopen this, please? The reason we are not leveraging elicitation on our side is because codex doesn't support it.

Maybe change the title of the issue to "Elicitation support", and add "upvote police" in the issue template?
