Codex Tools Account Manager

Skill by ara.so — Codex Skills collection.

Overview

codex-tools is a React + Tauri desktop application for managing multiple Codex accounts, monitoring usage quotas (5h/1week windows), and providing a local OpenAI-compatible API proxy. It supports account switching, automatic usage tracking, and public network exposure via cloudflared.

Primary use cases:

• Manage multiple Codex accounts and switch between them
• Monitor usage limits and intelligently select accounts with remaining quota
• Run a local /v1 API proxy that routes requests through Codex accounts
• Expose the proxy to the internet for tools like Cursor that block private IPs
• Automatically restart editors and sync OpenAI tokens after account switching

Account Management

Import Accounts

Method 1: OAuth Login

• Click the OAuth login button in the UI
• Follow the authentication flow
• Account token is automatically imported

Method 2: Upload JSON Files

Import single or multiple .json token files:

{
  "access_token": "your_access_token_here",
  "refresh_token": "your_refresh_token_here",
  "expires_at": 1234567890
}

Method 3: Import from Directory

Point the app to a folder containing multiple .json token files. All valid tokens will be imported in batch.

Method 4: Restore Backup

Import a previously exported accounts.json backup file.

Note: After import, the app restores your current logged-in account to avoid disrupting your active session.

Export Accounts

Export all accounts as accounts.json for backup:

{
  "accounts": [
    {
      "id": "account_id_1",
      "access_token": "token1",
      "refresh_token": "refresh1",
      "plan_type": "Pro",
      "usage_5h": 450,
      "usage_1week": 2000
    }
  ]
}

View Usage

The UI displays:

• 5h window: Requests used in the last 5 hours
• 1week window: Requests used in the last 7 days
• Plan type: Free/Pro/Business
• Last refresh: Timestamp of last usage check

Click "Refresh" to manually update, or wait for automatic refresh (default: every 5 minutes).

Switch Accounts

1. Select an account from the list
2. Click "Switch & Launch Codex"
3. The app will:
   • Write the new token to the local Codex config
   • Launch the Codex desktop app (or fallback to codex app CLI)
   • Optionally sync the OpenAI token to Opencode
   • Optionally restart your selected editor (VS Code, Cursor, etc.)

Smart Switch: Click "Smart Switch" to automatically select the account with the most remaining quota in the current window.

API Proxy

The proxy provides an OpenAI-compatible /v1 endpoint backed by Codex accounts.

Start the Proxy

UI:

• Navigate to "API Proxy" tab
• Click "Start Proxy"
• The proxy starts on http://127.0.0.1:8787/v1 (default)

Auto-start: Enable "Start proxy on app launch" in settings.

Configuration

Port:

• Default: 8787
• Custom: Set in the settings panel

API Key:

• Fixed key: Set a static key in settings
• Manual refresh: Click "Refresh API Key" to generate a new random key
• The key is used for Bearer token authentication

Account Selection: The proxy automatically selects the account with the most remaining quota when handling requests.

Usage Example

# Test the proxy
curl http://127.0.0.1:8787/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "model": "gpt-5.4",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

import openai

openai.api_base = "http://127.0.0.1:8787/v1"
openai.api_key = "YOUR_API_KEY"

response = openai.ChatCompletion.create(
    model="gpt-5.4",
    messages=[{"role": "user", "content": "Write a hello world in Rust"}]
)
print(response.choices[0].message.content)

import OpenAI from "openai";

const client = new OpenAI({
  baseURL: "http://127.0.0.1:8787/v1",
  apiKey: process.env.CODEX_PROXY_KEY,
});

const completion = await client.chat.completions.create({
  model: "gpt-5.4",
  messages: [{ role: "user", content: "Explain async/await in JS" }],
});

console.log(completion.choices[0].message.content);

Supported Models

• gpt-5.4 (recommended)
• gpt-5-4 (alias)

Add custom models in Cursor: Settings → Models → Add or search model

Cursor Integration

Cursor blocks private IP addresses (127.0.0.1, localhost, 192.168.x.x, 10.x.x.x) when used as OpenAI base URLs.

Solution: Use Public URL

Option 1: Cloudflared (Built-in)

1. Navigate to "Public Access" tab
2. Click "Start Cloudflared"
3. Copy the generated public URL (e.g., https://abc123.trycloudflare.com)
4. In Cursor:
   • Settings → Models
   • Enable "OpenAI API Key", paste your proxy API key
   • Enable "Override OpenAI Base URL", paste https://abc123.trycloudflare.com/v1
   • Add custom model gpt-5.4

Option 2: Named Tunnel

Configure a named cloudflared tunnel for a persistent URL:

# cloudflared config.yml
tunnel: your-tunnel-id
credentials-file: /path/to/credentials.json

ingress:
  - hostname: codex.yourdomain.com
    service: http://127.0.0.1:8787
  - service: http_status:404

Option 3: Remote Reverse Proxy

Deploy a reverse proxy on a public server:

# nginx.conf
server {
    listen 443 ssl;
    server_name codex.yourdomain.com;

    location /v1 {
        proxy_pass http://your-local-ip:8787/v1;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
    }
}

Cursor Configuration

1. Open Cursor → Settings → Models
2. Enable "OpenAI API Key", enter your proxy API key
3. Enable "Override OpenAI Base URL", enter your public URL with /v1
4. In "Add or search model", type gpt-5.4 and click "Add Custom Model"
5. Test by asking a question in Cursor chat

Cloudflared Public Access

Quick Tunnel

No configuration required. Generates a random .trycloudflare.com URL:

1. Click "Start Quick Tunnel"
2. URL appears in the UI (e.g., https://random-words-123.trycloudflare.com)
3. Share this URL or use in Cursor

Named Tunnel

Requires a Cloudflare account and tunnel setup:

1. Create a tunnel at Cloudflare Zero Trust
2. Download credentials JSON
3. In codex-tools: Settings → Cloudflared → Named Tunnel
4. Upload credentials and configure hostname
5. Click "Start Named Tunnel"

HTTP/2 Support

Enable HTTP/2 in settings for better performance with streaming responses.

Editor Integration

Restart Editor After Switch

Enable in Settings → Editor:

• VS Code
• Cursor
• Other (specify process name)

When you switch accounts, the app will:

1. Kill the editor process
2. Wait 2 seconds
3. Restart the editor

Sync OpenAI Token to Opencode

Enable in Settings → Integrations:

• Automatically sync the Codex OpenAI token to Opencode config
• Useful if you use both tools in parallel

CC Switch Integration

codex-tools can act as a custom provider for CC Switch:

{
  "providers": [
    {
      "name": "codex-local",
      "type": "custom",
      "base_url": "http://127.0.0.1:8787/v1",
      "api_key": "${CODEX_PROXY_KEY}",
      "protocol": "responses"
    }
  ]
}

The proxy follows the responses protocol for account selection and load balancing.

Troubleshooting

"App is Damaged" on macOS

sudo spctl --master-disable
sudo xattr -r -d com.apple.quarantine /Applications/Codex\ Tools.app

Cursor Shows ssrf_blocked Error

This means Cursor is blocking private IPs. Use a public URL via cloudflared or a reverse proxy (see "Cursor Integration").

Proxy Not Starting

• Check if port 8787 is already in use: lsof -i :8787
• Try a different port in settings
• Ensure you have at least one valid account imported

Account Import Fails

• Verify JSON structure matches the expected format
• Check token expiry: expires_at should be in the future
• Re-authenticate via OAuth if refresh token is expired

Usage Not Updating

• Click "Refresh" manually
• Check network connectivity
• Verify account tokens are still valid (re-login if needed)

Cloudflared Tunnel Fails

• Ensure cloudflared binary is installed and accessible
• For named tunnels, verify credentials file path
• Check Cloudflare dashboard for tunnel status

Editor Not Restarting

• Verify the editor process name in settings matches the actual process
• On macOS, grant codex-tools accessibility permissions if needed
• Try manually killing and restarting the editor

Configuration Files

Adding a New Feature

1. Define Tauri command in src-tauri/src/main.rs:

#[tauri::command]
async fn my_new_feature(param: String) -> Result<String, String> {
    // Implementation
    Ok(format!("Processed: {}", param))
}

fn main() {
    tauri::Builder::default()
        .invoke_handler(tauri::generate_handler![my_new_feature])
        .run(tauri::generate_context!())
        .expect("error while running tauri application");
}

2. Call from React frontend:

import { invoke } from "@tauri-apps/api/tauri";

const result = await invoke<string>("my_new_feature", { param: "test" });
console.log(result);

Running Tests

# Rust tests
cd src-tauri
cargo test

# Frontend tests (if configured)
