Charles Schwab has begun piloting a Model Context Protocol (MCP) server that allows select clients to connect Anthropic's Claude AI directly to their brokerage accounts, enabling them to prepare, place, and manage trades through the AI assistant. The move, announced on November 12, marks a significant step in integrating generative AI into retail investing.
The MCP server, an open standard for connecting AI tools to external software, is currently available to a limited group of clients using Claude. Schwab plans to expand access and add support for other AI platforms in the coming months. Once authorized, clients can pull market data, analyze portfolio performance, summarize holdings, create alerts, and organize investment information.
For clients with thinkorswim-enabled accounts, the integration goes further, allowing them to "prepare, place, and manage trades" through Claude, with the client remaining in the loop. Schwab emphasized that Anthropic is not affiliated with the broker, and the pilot follows the recent rollout of Charley, Schwab's own generative AI assistant.
James Kostulias, managing director and head of trading services at Charles Schwab, said the combination of platforms, education, research, and service staff "could be difficult for other brokerage firms to replicate." Schwab's scale is notable, with $13.33 trillion in total client assets and 10.7 million daily average trades in the third quarter.
In parallel, Schwab has extended options trading hours for approximately 30 popular stocks, ETFs, and indexes listed on Cboe Options Exchange. The list includes all of the Magnificent Seven and five index options, such as the S&P 500 Index (SPX), the Cboe Volatility Index (VIX), and the Russell 2000 Index (RUT).
The new sessions run Monday through Friday, with a pre-market window from 7:30am to 9:25am ET and a post-market window from 4:00pm to 4:15pm ET. The post-market session applies to single-stock options only, and trades placed then count towards the current trading day, helping clients avoid exercise and assignment. The morning session allows traders to react to overnight developments and company news.
Schwab cautioned that extended-hours trading carries extra risks, including lower liquidity, higher volatility, and wider spreads. Other platform updates include a thinkorswim Assistant, an AI-powered search tool expected to roll out soon, and expanded portfolio insights coverage. The broker also introduced an Order Gadget on thinkorswim showing per-leg options pricing, maximum profit, maximum loss, and breakeven before confirmation, plus a redesigned bonds page on Schwab.com.
These developments come as other brokers experiment with AI-assisted trading, but Schwab's scale and integration set it apart. The pilot and extended hours reflect a broader industry trend toward AI-driven tools and 24/7 trading access.
