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

The bank's stock-plan administration platforms — a $1.2 trillion funnel into its wealth arm — will let corporate clients' agents bypass human-facing interfaces, with a rollout to 3,400 administration clients planned for next year.

Morgan Stanley will open ShareWorks and Equity Edge, its two stock-plan administration platforms, to external AI agents over the Model Context Protocol, letting corporate clients’ software bypass the human-facing interfaces entirely. A handful of clients already have early access, and Mark Mitchell, chief product officer of Morgan Stanley at Work, told CNBC the bank plans to extend agentic connectivity to all 3,400 administration clients by next year.

The platforms aren’t incidental plumbing. Assembled from the 2019 Solium Capital acquisition and the 2020 E-Trade deal, ShareWorks and Equity Edge serve almost half of the S&P 500 and eight of the ten largest unicorn startups. In April, Morgan Stanley executives credited the workplace strategy with gathering $1.2 trillion in assets, the on-ramp into a wealth arm the firm describes as the world’s largest at $7.35 trillion in client assets. Administering equity plans is how the bank converts employees into advisory clients as their grants vest and their wealth grows.

Mitchell’s framing is unusually direct about the endgame. “The way we see it, in a future state, our corporate clients will not be logging into ShareWorks or Equity Edge.” Instead, he described them “using agentic AI-powered tools on their desktops within the four walls of their companies, interacting with our platforms in a purely agentic way.”

The institutional logic runs both ways. Fast-growing tech and biotech customers can administer increasingly complex equity plans without expanding HR headcount, and Morgan Stanley itself avoids hiring what Mitchell called “thousands and thousands” of employees to service them. It’s a labor-arbitrage story dressed as a product release.

That’s also what makes the MCP choice notable. JPMorgan Chase and Goldman Sachs have deployed AI agents internally, including for coding, but haven’t announced opening their own systems to clients’ agents. Morgan Stanley is betting the connective tissue between corporations and their financial infrastructure becomes a protocol layer, not a portal, and that whoever sits at the data endpoint keeps the customer.

Shares edged slightly higher on the report, per CoinCentral. The funnel is the product. The login screen, it turns out, was the friction.
