WAIaaS wallet MCP server

Let your AI check balances and send crypto from your own machine, with spending limits you control.

WAIaaS is a wallet program you run on your own computer. It lets an AI assistant look at your crypto wallets and make payments on Solana and Ethereum-style networks, while you keep the keys and set the rules. It is handy if you already use an AI assistant and want it to handle small crypto tasks without handing over your funds.

What is an MCP server? The 30-second version

On its own, your AI can only chat. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to your own WAIaaS wallet program, so the AI can check balances, send tokens, or look up transactions for you when you ask. The wallet program still runs on your machine, and your keys stay there.

What this MCP server does

You ask your AI something like send 0.1 SOL to this address. The AI passes the request to this MCP server, which talks to the WAIaaS wallet program running on your computer. That program checks your rules, like how much can be spent without asking you, and then sends the transaction to the blockchain. You get back a short answer in the chat, such as the transaction ID or a note that it needs your approval first.

Try asking your AI

“What is my Solana wallet balance right now?”
“Send 0.05 SOL to this address and show me the transaction ID”
“Show my last five transactions and their status”
“What are my current spending limits?”

What it gives back to you

You get plain answers in the chat: balances with the token symbol, transaction IDs, short lists of recent activity, and confirmations when a policy change or a transfer goes through. If a transaction is above your limit, it tells you it is waiting for your approval instead of sending it. Everything is a short reply, not a file you have to open.
