Environment / auth
  • FIATDOCK_URL

    FiatDock API base URL

  • FIATDOCK_TOOLS

    Install only the tool groups you need, so unused tools don't take up your agent's context: 'ramp' (4 tools: quotes, USDC<->bank sessions, order status), 'data' (11 tools: token price/safety/report, gas, balances, tx status, address intelligence), 'marketplace' (3 tools: search, inspect and pay for other agents' MCP services). Comma-separate to combine, e.g. 'ramp,marketplace'. Default: all 18. An unrecognised value serves all tools rather than none.

  • AGENT_PRIVATE_KEY
    secret

    Agent wallet key that auto-pays the x402 fee for paid tools ($0.001-$0.05 depending on the tool, plus whatever a marketplace seller charges). Optional: the five free tools (get_quote, get_order_status, token_price, search_services, get_service) work without it. Use a dedicated low-balance wallet.

  • FIATDOCK_MAX_PRICE_USD

    Price-bait guard for call_service: refuse to pay if a paid gateway call's total x402 charge exceeds this many USD. Optional (default: no ceiling); overridable per call via the maxPriceUsd argument.
