Variables d'environnement

  • ARENA_MCP_ALLOW_TRADE Set to 1 to register the paper-trade tools (place_trade, sell_trade, cancel_order, settle_open). Any other value leaves trading off.
  • ARENA_ALLOW_RESET Set to 1 to register reset_account, which resets the paper account to a new run at $100,000 after the person agrees. The server also refuses until the owner turns resets on in Settings on the web. Any other value leaves it out.
  • ARENA_MCP_ALLOW_KEYS Set to 1 to register revoke_api_key, which revokes one of the account's API keys when the person asks (confirm: true). Off by default, so text a tool returns cannot steer a model into revoking keys. list_api_keys is always registered. Any other value leaves it out.
  • ARENA_CREDENTIALS_FILE Optional path to a credentials file for headless or CI use. By default the server reads the credentials that `arena login` stored.
  • ARENA_API_KEY secret Optional Arena API key (arena_sk_...) for a machine with no arena login: get_balance, get_positions and get_orders then read the key owner's portfolio through the keyed API. A session always wins there. get_my_eval reads with it when it is set, else with the sign-in. Trade tools still need arena login.
  • ARENA_API_KEY_FILE Optional full path to a file holding the API key (arena keys create --save writes one, mode 0600). Used when ARENA_API_KEY is not set. With neither set, the server reads ~/.config/arena/arena.key when it holds a key (the file the CLI and the Python SDK read).
