How do I use iota-agent-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@iota-agent-mcp check my active wallet address and current IOTA balance" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

iota-agent-mcp

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
