The oldest unsolved problem in the IT industry is . . . secret and credential exposure and AI agents just made it worse! If you've been spinning up AI tools — Claude Desktop, Cursor, Copilot, and so on — there's a decent chance that API keys, credentials, and access tokens are sitting in plaintext on your laptop. With MCP, every quickstart guide tells you to paste your credentials right into a config file. That was a bad habit before. Now it’s worse because we’re handing keys to agents. William Collins has a new open-source project to help with that - gridctl.

On today’s show we talk with William Collins about gridctl, a new open-source project he’s working on that, among other capabilities, helps make sure that developers aren’t exposing sensitive stuff as they build MCP servers and agentic toolchains and workflows.

William is a cloud and automation engineer and co-host of The Cloud Gambit on the Packet Pushers podcast network.
