MCP for EOS: what it is and why it matters

Every headline this year says AI is changing how companies operate. Then Monday comes around, someone updates the Scorecard by hand, and a Rock owner gets asked for the third week running whether that project moved.

McKinsey’s State of AI report, published in August 2026, puts a number on that gap. At organizations above a billion in revenue, 40% now report scaling AI agents, up from 27% a year ago. At smaller organizations it’s 22% — flat, year over year. The big companies are pulling away, and it has very little to do with how clever anyone is.

It has to do with where your operating data lives. Your Rocks, your measurables, your Issues list — all of it sits inside an application that an AI assistant can’t see.

MCP (Model Context Protocol) is an open standard that connects an AI assistant to the systems where your data lives. For a company running EOS, an MCP connector lets Claude or ChatGPT read and update your Rocks, Scorecard, To-Dos and Issues directly, using your existing permissions.

We shipped one earlier this year. Most of the operators who beta-tested it for us had never heard the term before we emailed them 🤔. Below is the explanation we wish had existed then — what MCP is, what it changes for an EOS company, and the parts vendors leave out.
