title: 'Zero Cold Starts: Serverless AI Agents on Akamai Functions — Thorsten Hans'
description: >-
  Cold starts, proprietary SDKs and one-region deployments slow AI apps down.
  WebAssembly at the edge removes all three. Thorsten Hans, senior developer
  advocate at Akamai, shows how to build and ship MCP servers and AI agents with
  Spin, the open-source WebAssembly framework, and run them on Akamai Functions,
  a globally distributed serverless platform with no cold starts. He explains
  why WebAssembly on the server is fast, portable and sandboxed by default, then
  live-codes MCP servers with wasmcp: scaffolding tools in TypeScript and Rust,
  composing them into a full server, testing with MCP Inspector, deploying it
  worldwide in about 60 seconds with one command, and calling its tools from the
  Zed editor. He finishes with an agent built on the Vercel AI SDK, backed by a
  model on a Linode GPU, and explains how memory snapshots keep apps warm. In
  this talk: • Why edge-native beats single-region for AI apps, and how
  WebAssembly kills cold starts • What Spin and Akamai Functions are • Building
  and composing MCP servers with wasmcp in TypeScript and Rust • Deploying an
  MCP server and an AI agent globally with one command SPEAKER Thorsten Hans,
