Morgan Stanley opens ShareWorks and Equity Edge to external AI agents over MCP

The bank will let 3,400 corporate clients point their own agents at the platforms behind $1.2 trillion in workplace assets, bypassing the human UI entirely.

Morgan Stanley will let corporate clients connect their own AI agents directly to ShareWorks and Equity Edge, the stock-plan administration platforms that sit underneath $1.2 trillion in workplace assets, using the open-source Model Context Protocol as the connective layer. A handful of clients already have early access. The rest of the 3,400-company roster gets it by next year.

The framing matters because it’s one of the first cases of a major Wall Street bank pointing external agents at core client-facing systems rather than confining the technology to internal scaffolding. JPMorgan Chase and Goldman Sachs, per CNBC, have kept their AI deployments to things like code generation. Morgan Stanley is doing the opposite: opening the doors and assuming the humans stop walking through them.

Mark Mitchell, chief product officer of Morgan Stanley at Work, said it plainly in an exclusive CNBC interview. “The way we see it, in a future state, our corporate clients will not be logging into ShareWorks or Equity Edge,” he said, describing them instead “using agentic AI-powered tools on their desktops within the four walls of their companies, interacting with our platforms in a purely agentic way.” That clients “won’t be logging into” the websites his unit operates, he added, “doesn’t scare us at all.”

The underlying bet is about what’s actually defensible. “The companies that are going to survive in the future are the ones who have proprietary data and business logic, which is the foundation of our offering,” Mitchell said. Translation: UI traffic was never the moat. The moat is administering stock plans for nearly half the S&P 500 and 8 of 10 largest unicorns, a position built through the 2019 Solium Capital deal and the 2020 E-Trade acquisition, and credited by executives in April with gathering the $1.2 trillion that now sits inside the $7.35 trillion wealth book.

Morgan Stanley at Work has been partnered with OpenAI since 2022. MCP, in this telling, is just the plumbing that makes the longer thesis legible to corporate IT departments. The bank is betting it can be the substrate other people’s agents call, and that being called is worth more than being clicked.
