PrimeXBT has connected ChatGPT and Claude to client accounts through the Model Context Protocol (MCP), adding a human approval step to AI-prepared orders. The launch follows B2Broker's addition of similar connectivity to B2TRADER last week. Their permission models diverge: PrimeXBT requires approval for every order, while B2TRADER lets brokers decide how much control an agent receives.
Both live and demo accounts on PXTrader 2.0 are supported, with access to CFDs and crypto futures. PrimeXBT says the assistant uses live account information and the broker's knowledge base to answer questions about costs, margin requirements and platform rules. Traders connect through one link using their PrimeXBT login, then choose Read-only or Read & Trade. The assistant cannot move or withdraw funds.
PrimeXBT has also introduced a Trading API for algorithmic and quantitative traders who want to connect their own bots and dashboards. It supports order and position operations behind two-factor authentication, with IP restrictions available as an option. The broker says the API, like MCP, cannot move money.
Approval rules vary across platforms
- PrimeXBT: The assistant prepares market, limit or stop orders, but the trader must approve each one. Before that decision, it displays estimated price, fees, margin, use and liquidation level.
- Leverate and Capital.com: Leverate's MCP for Traders presents size, price, stop levels and the margin effect before requesting approval. Capital.com's server for Middle East and North Africa clients previews a trade and uses two-step confirmation.
- Interactive Brokers and Axi: Claude drafts an instruction at Interactive Brokers, where the client turns it into an order. Axi clients can set an action to always allow, removing Claude's confirmation prompt for that action.
- B2Broker: Brokers can turn MCP off, provide read-only access or grant full access. Agents with the broadest permission can place, modify and close permitted trades without individual approval. B2TRADER's own AI Chat, however, asks clients to confirm its proposed orders.
Broker adoption has broadened
At least six brokers and trading-technology firms have allowed AI assistants into client accounts since June, according to reporting by Finance Magnates. Interactive Brokers extended its connector in July to work with almost any MCP-based tool. In a leveraged crypto position, the liquidation estimate changes with price; PrimeXBT's crypto futures range had grown by 101 coins in September 2025.
Jonatan Randin, senior market analyst at PrimeXBT, said MCP brings "real trading data and functionality into the AI assistants people already know and use." B2Broker founder and CEO Arthur Azizov said adding AI to a terminal "raises an immediate question: who decides what an assistant can actually do?" B2Broker describes read-only access as suitable for AI marketplaces and expects its in-terminal chat to reduce routine support inquiries. It says an agent sees only the accounts of the trader who authorised it. The MCP layer is the third phase of B2TRADER's AI programme, following an assistant launched in April with market forecasts, sentiment indicators and trading signals.
Where this lands in the stack
For trading operations, these integrations add another permissioned route to order handling. The control point differs by platform: PrimeXBT puts approval on every order, while B2TRADER lets brokers configure agent access and permits execution without a separate confirmation under full access. The source does not specify how these actions appear in existing audit logs or reconciliation workflows.
Before enabling an assistant, operators should establish who grants and revokes its account access, which permissions apply, and how its proposed or executed orders flow into existing controls. They should also confirm what the client sees before approval and whether their chosen configuration requires confirmation per order. The source gives no operating-cost figures, so those costs remain a question for each broker and provider.
