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.
What is the default Nano network for x402?
The default network is "nano:mainnet", configurable via the X402_NANO_NETWORK environment variable.
Can I use a remote Nano node?
Yes. Set NANO_RPC_URL to any Nano node RPC endpoint, whether local or remotely hosted.
