nano-wallet-xno

Nano (XNO) wallet as a local stdio MCP server, Python standard library only. Tools: `create_address`, `validate_address` (checksum-checked, returns a machine-readable reason), `balance`, `receive`, and `send` in the full profile. `--profile receive-only` does not register `send` at all (`-32601`), and `nano-wallet selfcheck --profile receive-only` proves that on the install it runs on. In the full profile `send` is refused unless `NANO_WALLET_ALLOW_SEND=1`, and can be bound to an operator-signed mandate (total cap, per-payment max, payee allow-list, expiry). Keys are generated and blocks signed locally; amounts are integer raw. Install: `pip install "git+https://github.com/dhyabi2/nano-wallet-xno"`, then run `mcp_server.py --profile receive-only`. MIT.
