Overview

What is kosa8?

kosa8 is secure infrastructure for AI agents. Every agent gets its own sealed machine: a real microVM with its own kernel, not a container sharing the host's.

Key features

  • Closed network: only hosts on an allow-list you write answer
  • Use API keys without holding them: an egress broker on the host injects them on the way out
  • Checkpoint the whole running machine in about 0.7 s and rewind it in about a second
  • Fork a running sandbox into live copies to try approaches in parallel
  • Human approval gates (one or two named approvers) for risky actions
  • Tamper-evident, hash-chained audit log
  • Docker-compatible and MCP-native; runs on Apple-silicon Macs, x86-64 Linux and Windows via WSL2

How to use

  1. Install kosa8 from https://kosa8.com/download/ and run kosa8 daemon start.
  2. Add the server to your MCP client: command kosa8, args mcp serve (stdio).
