In about three years Stacklok has changed its product twice, from software supply-chain security, to protecting AI coding assistants, to today's platform for running the connectors that let AI agents use company tools. Each time it gave away or retired the prior flagship. What survives every pivot is the team, the creators of Kubernetes and Sigstore, and a strategy of building in the open. Its ToolHive project is free, counts external maintainers from Red Hat, and is planned for donation to an open-source foundation. It is betting that owning the default open-source way to run these connectors safely beats owning a proprietary product a bigger vendor can copy or bundle. Snowflake's announced intent to acquire another enterprise MCP platform, Natoma, shows how fast that bundling can start.
