Keyban Agent Wallet

Overview

Keyban Agent Wallet is a Model Context Protocol server that gives AI agents their own blockchain wallet. It enables agents to check balances, transfer USDC, and make x402 payments under policy—all integrated directly into your AI assistant as native tools.

The server runs locally via the npm package @keyban/cli, which communicates over stdio. You'll need to set three environment variables: KEYBAN_API_KEY, KEYBAN_APP_ID, and KEYBAN_INVITE_KEY. The latest release is v0.1.0, available from https://keyban.io.

Keyban Agent Wallet is listed in the Finance category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim this listing to verify ownership and keep information up to date.
