If AI agents are the new workforce, MCP is the badge system that decides which buildings they can enter.
MCP stands for Model Context Protocol. It’s the standard that lets an AI agent connect to your actual systems — CRM, finance, document libraries — without a custom integration built for every single pair. One standard plug instead of a hundred bespoke wires. Every major vendor now speaks it: Microsoft, Anthropic, OpenAI, Google, Salesforce.
On July 28 it got its biggest overhaul since launch. You don’t need the engineering details. You need what they mean for you.
It now scales like normal infrastructure. The old version needed special handling to run at enterprise size. The new one runs on the same boring, reliable plumbing as everything else in your stack. Fewer exotic failure modes, lower cost to operate.
Security moved to where your IT team already lives. What agents can touch is now controlled through your identity provider — the same system that governs employee logins. Sign in once, IT decides which doors open. Your security team stops approving connections one at a time.
And there’s a 12-month clock. Older versions are being phased out. If your organization has agents in production — and most now do, sometimes without leadership knowing — someone owns a migration plan. Worth asking who.
The pattern underneath: agent infrastructure just stopped being experimental and started being governed like everything else you run. That’s not a slowdown. That’s what technology does right before it becomes load-bearing.
A question worth bringing to your next ops review: which of our agents can reach which systems, and who decided?
