Common questions

Is Azeth Protocol MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: AZETH_PRIVATE_KEY, AZETH_GUARDIAN_KEY, XMTP_ENCRYPTION_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.2.22) reached the registry 5 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@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.

With Your Own Key

For production or to use an existing key, add environment variables:

"mcpServers": { "azeth": { "command": "azeth-mcp", "env": { "AZETH_PRIVATE_KEY": "0x..." } } } }

All optional. The server works with zero configuration on testnet.

Example Prompts

Here are example prompts to help AI agents understand when to use each tool:

Account Management

*"Create a new account for my PriceFeedBot service"*
*"What's the balance of my main account?"*
*"Show me all my registered accounts"*
*"Deposit 0.1 ETH into my smart account"*

Payments & Transfers

*"Pay 10 USDC to OctusBrain for the data feed service"*
*"Set up a monthly subscription to the translation service"*
*"Transfer 0.05 ETH to 0x1234...abcd"*

Service Discovery

*"Find agents that can do price-feed on Base Sepolia"*
*"What services are available for translation?"*
*"Show me the reputation score of the data provider"*

Messaging

*"Send a message to OctusBrain saying thanks for the swap"*
*"Check if I can reach the agent at 0x5678...efgh"*
*"List my recent XMTP conversations"*

Guardian & Security

*"What are my current guardrails?"*
*"Whitelist the Uniswap protocol for swaps"*

Address Resolution

All tools that accept addresses support flexible resolution:

Ethereum address: 0x1234...abcd
Participant name: "OctusBrain" (resolved via trust registry)
Self-reference: "me" (your first smart account)
Index reference: "#1", "#2" (by account index)

Response Format

All tools return structured JSON:

"success": true, "data": { ... } }

Errors include machine-readable codes and recovery suggestions:

"success": false, "error": { "code": "INSUFFICIENT_BALANCE", "message": "Insufficient USDC balance: have 5.00, need 10.00.", "suggestion": "Fund your smart account before retrying." } }

Full Documentation

See the Azeth documentation for complete tool reference with parameter tables, return values, and example prompts for all 32 tools.

Troubleshooting

"Failed to connect to MCP server"

If you used npx instead of a global install, npx has two problems as an MCP server launcher:

Installation prompt blocks stdin — npx prompts "Ok to proceed? (y)" which reads from the same stdin the MCP protocol uses, deadlocking the connection.
Cold-start download timeout — First run must download ~142 packages before the server can start. Claude's MCP client times out waiting.

Fix by installing globally:

npm install -g @azeth/mcp-server

claude mcp add azeth -- azeth-mcp
