What issue are you seeing?

Title: /mcp status output is unreadable when many plugin tools are enabled

Product and environment:

• Codex CLI/TUI: 0.147.0
• Codex desktop-bundled engine: 0.147.0-alpha.6.6
• Operating system: Windows
• MCP servers: codex_apps and node_repl
• Active plugins/connectors include GitHub, Gmail, Google Calendar, Google Drive, Linear, Slack, Browser, Documents, PDF, Presentations, Spreadsheets, Sites, and others.

Problem:
Running the built-in /mcp slash command produces a very large, poorly structured status display. Authentication labels, tools, resources, and resource templates are rendered as long inline sections. With hundreds of tools exposed by codex_apps, the output becomes an unreadable wall of text.

The display includes labels such as:

• Auth: Not logged in
• Bearer token
• Tools
• Resources
• Resource templates

“Bearer token” appears to be an authentication-method label rather than an exposed credential, but its placement is confusing and makes the output look as though authentication data is mixed into the tool list.

Expected behavior:
The /mcp view should present each server as a clearly separated, readable block. For example:

Server: codex_apps
Status: Connected
Authentication: [concise status]
Tools: 361 available
Resources: 0
Resource templates: 0
[Expand or search tools]

Server: node_repl
Status: Connected
Transport: STDIO
Authentication: Not applicable
Tools: 3 available
Resources: 0
Resource templates: 0

Large tool catalogs should be collapsed, paginated, searchable, or summarized by count. Authentication status should be visually separated from tool names. Credential values must remain redacted.

Actual behavior:
The complete tool catalog is printed inline alongside authentication and resource information. The result is difficult to scan, wraps badly, and makes the relationship between servers, authentication methods, and tools unclear.

Reproduction steps:

1. Enable plugins/connectors that expose a large number of tools.
2. Ensure codex_apps and node_repl are connected.
3. Open a Codex chat.
4. Enter /mcp.
5. Observe that the complete tool catalog and authentication labels are rendered in a long, hard-to-read layout.

Diagnostic findings:

• codex_apps and node_repl initialize successfully.
• MCP tool calls execute successfully.
• The node_repl MCP process remains running.
• An independent MCP initialization handshake succeeds using protocol version 2025-06-18.
• Logs show zero unavailable MCP servers after successful initialization.
• This is reproducible after starting a new thread and restarting Codex.
• The problem is specific to the built-in /mcp presentation; it is not an MCP connectivity failure.
• The MCP server responses themselves are valid.
• There are two installed Codex executables, but /mcp is rendered by the Codex client, and reinstalling the standalone CLI would not address this UI path.

Suggested improvements:

1. Group output by MCP server.
2. Show connection and authentication status as dedicated fields.
3. Summarize tools, resources, and templates with counts.
4. Collapse large tool lists by default.
5. Add expansion, paging, filtering, or search.
6. Display “Not applicable” for authentication on local STDIO servers instead of “Unsupported.”
7. Clearly distinguish an authentication-method label such as “Bearer token” from an actual configured credential.
8. Preserve redaction for all secrets.
9. Handle terminal/window width and line wrapping gracefully.
10. Avoid showing a stale “MCP startup interrupted” banner after all servers subsequently initialize successfully.

Please review both the /mcp status renderer and the handling of transient startup-state updates. I am including logs with this feedback.

What steps can reproduce the bug?

Uploaded thread: 019ff6ec-d547-7c02-a9e3-c05d737e1538

What is the expected behavior?

Show the MCP servers in a readable form.

Additional information

Using the /MCP command in the CLI should show a readable list of MCP, not the raw response from the server.
