mhub_proxy

mhub_proxy is a local OpenAI/Anthropic-compatible proxy that lets CLI tools (for example, Opencode) send OpenAI/Anthropic-style requests to SecureGPT.

Requirements:

uv is required to install and run the proxy.

curl -LsSf https://astral.sh/uv/install.sh | sh

Or, using pip:

pip install uv

Install mhub_proxy

Install as a uv tool:

uv tool install mhub_proxy

Required environment variables

Before starting the proxy, define the variables used by mhub_proxy/config.py:

• MHUB_API_URL : URL of the Model Hub API (Example: https://api-pp.se.axa-go.applications.services.axa-tech.intraxa/ago-m365-securegpt-hub-v1-vrs)
• MHUB_CLIENT_ID : Client ID for the Model Hub API
• MHUB_CLIENT_SECRET : Client Secret for the Model Hub API
• ONEACCOUNT_LOGIN_URL : URL of the OneAccount login API (Example: https://onelogin.stg.axa.com)

Optional:

• MHUB_PROXY_HOST (default: 127.0.0.1)
• MHUB_PROXY_PORT (default: 8123)
• MHUB_PROXY_LOG_LEVEL (default: info)

Run the proxy

Start the proxy with:

uvx mhub_proxy

By default, the proxy runs on http://127.0.0.1:8123.

Use with Opencode

1. Optionally:

   • Install the bundled OpenCode configuration in your project by running:

   uvx mhub_proxy --install-config
   

   • Or, add an opencode.json file to the root of your project and configure it to point to the proxy URL (see the Opencode Documentation or this example).

IMPORTANT: Notice how for OpenAI models the API version is included in the model ID, e.g. gpt-5.1-2025-11-13@2025-01-01-preview. This is required for the proxy to correctly route requests to the Model Hub API.

2. Start Opencode from a terminal inside your project directory.

Note: The included opencode.json points Opencode to the local proxy URL:

"baseURL": "http://127.0.0.1:8123/openai"

"baseURL": "http://127.0.0.1:8123/claude"

3. Use the /connect command in Opencode and choose SecureGPT OpenAI or SecureGPT Anthropic as your provider. You can use any values for the API key as the proxy does not validate it.

4. Choose a model from the Model Hub and start using Opencode as normal!

Automatic startup (Windows)

To automatically start the proxy when your PC boots up, you can create a scheduled task:

1. Open Task Scheduler and create a new task.

2. In the "General" tab, give the task a name (e.g., "Start mhub_proxy") and select "Run whether user is logged on or not".

3. In the "Triggers" tab, create a new trigger that begins "At startup".

4. In the "Actions" tab, create a new action that starts a program with the following settings:

   • Program/script: powershell.exe
   • Add arguments:

-NoProfile -ExecutionPolicy Bypass -WindowStyle Hidden -Command "Start-Process -WindowStyle Hidden -FilePath 'powershell.exe' -ArgumentList '-NoProfile -Command uvx mhub_proxy'"

5. Save the task and run it to verify that the proxy starts correctly.

Notes

• The proxy expects OpenAI chat-completions style traffic from your CLI tool.
• If startup fails, first verify that all required environment variables are set.
