• Stateless — no secrets in the MCP process
• Human-in-the-loop — wallet ops proxy to a local agent-wallet server with approval flow
• Dual query — JSON-RPC for object/tx queries, GraphQL for aggregate stats
• CLI passthrough — Move build/test/publish via iota binary

Quick Start

Install

npm install -g iota-agent-mcp

    "iota": {
      "command": "npx",
      "args": ["iota-agent-mcp"]
    }
  }
}
