Codex CLI doesn't know about the MCP in conversation

What version of Codex is running?

codex-cli 0.40.0 , codex-cli 0.39.0

Which model were you using?

gpt-5-codex

What platform is your computer?

Darwin 24.6.0 arm64 arm

What steps can reproduce the bug?

Install some MCP like context7

codex
/approvals
# select 3. Full Access

outcome is something like this dialogue

▌ list the available MCP server

• Ran zsh -lc ls

• Ran zsh -lc 'rg "MCP"'

■ Conversation interrupted - tell the model what to do differently

▌ what MCP do you have access to

• Ran zsh -lc 'ls -a'

• Ran zsh -lc 'cat .mcp.json'

> Available MCP server: graphiti-memory (SSE) at http://localhost:8000/sse.

▌ what MCP tool can you call?

> I only see the configured MCP server (graphiti-memory), but I don’t have
  visibility into its tool list from here. If you know it’s running, you can either
  share its tool manifest or ask me to query it with the appropriate client command.

================CODE SNIPPETS================TITLE: Create and Run a New Next.js App
(Quick Start)DESCRIPTION: Demonstrates the quickest way to scaffold a new Next.js
application named `my-app` using the `create-next-app` CLI with default settings.
The commands create the project, change into the new directory, and start the
development server. Examples are provided for pnpm, npm, yarn...

> Create & Run Next.js App

  - Run pnpm create next-app@latest my-app --yes then cd my-app and pnpm dev; same
  flow works with npm, yarn, or bun (npm run dev, yarn dev, bun dev). Source: /
  vercel/next.js docs (Installation quick start).
  - To walk through prompts interactively, use npx create-next-app@latest (or yarn
  create next-app, pnpm create next-app, bunx create-next-app) and follow the CLI
  questions.
  - When you need a starter template, add --example <template> to the command (e.g.,
  --example blog my-blog) to scaffold from featured examples.

  Let me know if you want steps for deploying or customizing the initial setup.

▌ list the available MCP servers

• Ran zsh -lc 'cat .mcp.json'

▌ what MCP can I use here?

> You can use the graphiti-memory MCP server (type: sse, URL http://localhost:8000/
  sse).

But the graphiti-memory server was installed for Claude Code before, and I removed it later.
In some other dialogue Codex CLI just says "None" or saying it needs approvals to access MCP.

What is the expected behavior?

list all the MCP available like in /mcp command

What do you see instead?
