Tether has expanded its open-source Wallet Development Kit with a new beta command-line interface and a Model Context Protocol server. These additions allow developers to manage wallet functions programmatically via terminal commands or AI-assistant integrations.
Why it matters
These tools simplify the integration of wallet management into automated workflows and LLM-based development environments. By leveraging the Model Context Protocol, Tether enables AI models to interface directly with cryptographic keys and wallet states in a standardized manner.
The new interface is currently available as version 1.0.0-beta.3 and requires Node.js 22.18.0 or later to run. The integrated Model Context Protocol server routes requests through a local daemon and enforces a five-minute unlock time-to-live for all wallet operations.
The players
Tether
A developer of digital asset infrastructure and the issuer of the Tether stablecoin.
The details
The command-line interface, or CLI—a text-based tool for interacting with software—supports fundamental tasks including wallet creation, import, export, locking, and unlocking. The new Model Context Protocol server exposes 11 distinct tools that act as bridges between AI models and the wallet's internal functions. By using a local daemon—a background process that handles requests without user intervention—the system maintains session security with a strict five-minute expiration window on unlocked wallet states.
Timeline
Oct. 17, 2025: Tether released the initial open-source Wallet Development Kit.
Sept. 26, 2026: Tether introduced the beta command-line and Model Context Protocol tools.
The Tech Race
This development marks Tether's effort to standardize wallet integration within the broader Model Context Protocol ecosystem. It positions the firm alongside other infrastructure providers racing to make local security tools accessible to autonomous AI agents.
Developers building on the kit can now integrate wallet management directly into their terminal scripts or AI-driven workflows. Users must ensure their local environment is updated to Node.js 22.18.0 or later to access these beta features.
The takeaway
Tether is lowering the technical barrier for automated asset management by bringing wallet controls to the CLI and MCP ecosystems. Developers should monitor the project's repository for the transition from the 1.0.0-beta.3 release to a final stable build.
