xno-mcp Purse Custody (Addresses Only)

If xno-mcp is available, treat it as a private wallet custody service:

• The LLM should ask xno-mcp to create a named purse (e.g. "A") and only return addresses.
• Do not ask the user to paste mnemonics/seeds into chat when a purse can be used instead.

Create a purse

Call MCP tool:

• purse_create with { "name": "A", "format": "bip39", "count": 1 }

Expected result shape:

• purse name + format
• A[0] address (nano_...)

Get more addresses (indexes)

• purse_addresses with { "name": "A", "fromIndex": 0, "count": 5 }

Configure good defaults (RPC URL)

To avoid each agent having to remember an RPC endpoint, set xno-mcp defaults once:

• config_set with { "rpcUrl": "<node-rpc-url>", "timeoutMs": 15000 }

Then purse_balance / purse_probe_balances can omit rpcUrl.

Check balance without exposing secrets

• purse_balance with { "name": "A", "index": 0, "includeXno": true }
• purse_probe_balances with { "name": "A", "count": 5 }

Notes

• Purse persistence is optional and off by default. If enabled, it’s stored as plaintext JSON under .xno-mcp/ (treat that directory as secret material).
