FAQ from Nano Currency MCP Server

What environment variables are required?

NANO_RPC_URL is required. NANO_PRIVATE_KEY, NANO_WORK_GENERATION_URL, RAW_MAX_SEND_AMOUNT, NANO_MAX_SEND_AMOUNT, and X402_NANO_NETWORK are optional but needed for sending transactions and x402 features.

How do I limit the amount of Nano that can be sent?

Set RAW_MAX_SEND_AMOUNT or NANO_MAX_SEND_AMOUNT to restrict the maximum per transaction. The default is 0.01 nano (or equivalent in raw).

Does this server support x402 payments?

Yes. The tool x402_payment_signature_exact_scheme_create creates the PAYMENT-SIGNATURE header for a Nano x402 transaction following the exact scheme.
