B2PRIME announced a branded connector in Claude’s directory on 27 October, allowing eligible clients with active B2TRADER accounts to examine market information and their own trading history inside the AI assistant. The directory connector is read-only: it can supply information for analysis but cannot place or change trades.[1]
The broker describes uses including historical-price comparisons and reviews of clients’ trading performance without exporting account history into spreadsheets. The release extends its existing AI strategy into an external assistant, following the AI Assistant introduced inside B2TRADER in June. It does not announce that every form of AI connection has the same authority.[1]
Order permissions depend on the connection
B2PRIME’s technical documentation distinguishes its two external connections using Model Context Protocol (MCP). The read-only version exposes 23 tools covering market data, balances, margin, positions, history and analytics. The separate full-access version exposes 39 tools, adding order actions and other account changes. The trading functions are absent from the read-only tool set, rather than merely awaiting a chat instruction.[2]
Three documented AI routes and their trading authority
| Connection | Order authority |
|---|---|
| Directory-listed read-only connection | Analysis tools only; no order placement, cancellation or closing.Source 2 |
| Separate full-access MCP connection | Can submit, cancel and close orders and set triggers without confirmation for each action.Source 3 |
| AI Assistant inside B2TRADER | Asks the client to confirm each trade before execution.Source 4 |
For an external connection, the documented sign-in uses OAuth 2.1 with PKCE: the client authenticates with the trading platform and the assistant receives a scoped access token. The client does not paste a brokerage password or API key into Claude. Choosing full access adds an explicit consent screen for trading authority before a token is issued.[3]
Account status also limits access. The documentation says an inactive account can complete sign-in but its tool calls are rejected. Brokers using B2TRADER may restrict or disable the connection capability, so the platform documentation describes available functionality rather than proving that every deployment offers it.[2]
Removing access has two parts
B2PRIME’s safety guide distinguishes disconnecting the assistant from revoking its account permission. Removing the connector stops the assistant making new calls. Revoking the grant in the account console prevents it obtaining another token, but an already issued token remains valid until expiry. The documentation does not describe an immediate broker-side invalidation switch for that existing token.[4]
That distinction is most consequential for the separate connection that can trade autonomously: a completed market transaction cannot be reversed merely by disconnecting the assistant afterwards. The new read-only connector excludes those execution functions, while still giving the assistant access to the account information authorised through the connection.[4]
B2PRIME presents the analytical output as an additional research input and says clients should check the underlying information. Access to real account records can make a review more specific, but it does not independently validate the assistant’s interpretation or demonstrate that a suggested strategy will improve returns.[1]
