Integrate once. Keep your systems yours.
MCP is an add-on channel that connects the trading and account systems you already run to the assistants your customers already use. It is not a replacement for your core infrastructure.
Four layers.
The MCP interface
A single broker-neutral interface that assistants and agents integrate against. Self-describing, so agents discover what they can do rather than being hard-coded against a bespoke API.
Canonical data model
One consistent representation of quotes, orders, positions, accounts and payments, regardless of what sits underneath at each broker.
Certified adapter layer
One certified adapter per broker, working against the licensed server APIs you already hold. Your proprietary components can be swapped without affecting anything built on top.
Controls and audit
Where the real work sits: asserting where a trade occurs and in whose regulatory space, appropriateness when a non-human places a trade, leverage and negative-balance protection, and audit trails proving who authorised each action.
From account opening to conversational trading.
Account opening
As the customer's account is created, a matching entry is created in the MCP account registry.
Discovery
The customer is told they can use their broker's official MCP connector, with simple instructions for adding it to their assistant.
Authentication
On connecting, the customer authenticates with their broker email via a magic link. No credentials pass through the assistant.
Trading
The customer trades conversationally, inside the assistant they already use every day.
Expansion
Personalised tools, richer analytics and proprietary services layer on under your own MCP extensions.
