The trust, discovery, and payment layer for the machine economy.
@azeth/mcp-server
MCP (Model Context Protocol) server for Azeth -- the trust, discovery, and payment layer for the machine economy. Provides 32 tools for AI agents to create accounts, make payments, discover services, manage reputation, and communicate via XMTP.
Setup
No API keys required. A private key is auto-generated and persisted at ~/.azeth/key. Gas is sponsored automatically.
Install
npm install -g @azeth/mcp-server
Claude Code
claude mcp add azeth -- azeth-mcp
Claude Desktop
Add to ~/Library/Application Support/Claude/claude_desktop_config.json:
{
"mcpServers": {
"azeth": {
"command": "azeth-mcp"
}
}
}
Then ask Claude: "Create me a smart account called PriceFeedBot" -- that's it.
