Let AI Agents Sign In and Act on Your Behalf | Internet Identity MCP Server

AI agents can talk about your apps. Now they can act in them, securely, as you. In this demo, we're joined by Arshavir, Senior Software Engineer and Team Lead, to walk through the new MCP server for Internet Identity. This new feature will let an AI agent like Claude or ChatGPT sign in on your behalf and act across every app you use, without handing over passwords or private keys. We cover how it works, run a live demo creating and editing a post on Taggr through ChatGPT. Arshavir explains why agents are the wrong place to manage keys, how the MCP server holds them in a trusted execution environment, and what read-only permissions will unlock next. What you'll learn: What the Internet Identity MCP server is and the problem it solves How agents authenticate and receive short-lived delegations The full tool set: discoverCanister, findCanister, lookupCanister, getCandid, callCanister, getPrincipal, and more The killer use case for mobile: one agent acting across many apps Why agents can't hold your keys, and the trusted execution environment approach that makes it safe Read-only vs full permissions, and where the feature is headed The MCP server is in preview today.
