## FAQ

### Can I execute stock trades with this MCP?

No, this MCP is for inquiry only. It does not execute orders (buy, sell, modify, or cancel). For trading, you must use the nhplug-sdk.

### What assets are supported?

The current version supports domestic stocks (krstock) and overseas stocks (gbstock). Other asset classes can be added by adding an openapi.json to the specs folder.

### How can I verify if my connection is working?

You can run the self-test script locally after filling in your APP_KEY and APP_SECRET in a .env file using the command 'node scripts/selftest.mjs'.
