> The tools let compatible AI clients access selected functions through a locally managed wallet while users retain control of wallet credentials.

Tether has added beta command-line and Model Context Protocol tools to its Wallet Development Kit, allowing compatible AI clients to access selected functions in a locally managed, self-custodial wallet.

The @tetherto/wdk-cli documentation lists version 1.0.0-beta.3 and requires Node.js 22.18.0 or later. The MCP server routes requests through the same local daemon used by the command-line interface.

The CLI supports wallet creation, import, export, unlocking and locking. It can also derive addresses, check balances and transfer history, and preview or broadcast transfers.

The MCP server exposes 11 tools, including functions for addresses, balances, transaction history and token transfers. It does not provide wallet creation, import, export, unlock or lock commands, so a wallet must be unlocked before wallet-dependent MCP functions can run. The example uses a five-minute unlock TTL.

MCP clients do not receive a wallet’s seed or passphrase as tool input. An unlocked wallet does not require the passphrase again to sign or send transactions, and another process running under the same operating-system user may be able to request signing or sending transactions.

Users should test the system with dedicated wallets and limited funds.

Tether released its open-source Wallet Development Kit on Oct. 17, 2025, presenting it as a toolkit for humans, machines and AI agents building multi-chain, self-custodial wallets.

“Self-custodial wallets are the cornerstone of a free and resilient monetary infrastructure,” Tether CEO Paolo Ardoino said. “We imagine a world where humans, autonomous machines, and AI Agents have the freedom to control their own finances.”
