17 Jun, 2026

If you are exploring the new world of the Model Context Protocol (MCP) and trying to install the GitHub MCP server on IBM Bob, there is a good chance the documentation pointed you toward Docker. But what if you use Podman as your open-source, daemonless alternative? In theory, Podman's command compatibility should make the transition seamless. In practice, AI tools or managers like Bob/VS Code can run into unexpected environment issues. In this post, we will look at how to properly configure Podman for the GitHub MCP Server and, more importantly, how to resolve the persistent command-not-found (ENOENT) error, even after setting up terminal aliases.
