Resources | NinjaTrader Developer Docs

Beta, pre-release. The NinjaTrader MCP server and its trading skills are in beta and aren’t yet generally available. The beta runs on Demo only, which trades simulated money. Live access opens later. Server hostnames, the tool set, the skills, and the onboarding flow may change before launch.

In addition to tools, the NinjaTrader MCP server exposes resources: named, read-only data sources your agent can read on demand or subscribe to for live updates. Where a tool is an action the agent calls, a resource is data the agent can watch.

Each resource has a tradovate:// URI and returns JSON. All resources provide read-only access, and the same account permissions as the equivalent tools apply.

Available resources

Subscriptions

The server supports resource subscriptions: a client can subscribe to a resource and receive a notification when its data changes. Today the server emits change notifications for the account-list, positions, and orders resources only. The server accepts a subscription to product-catalog, kalshi-events, or service-status but sends no updates for them, so reread those resources on demand. This lets an agent keep an up-to-date view of your positions and orders as fills and cancellations happen, without polling. Whether and how subscriptions surface in your workflow depends on your AI client’s MCP support.

Resources complement tools rather than replace them. For example, the positions resource gives a live view of open positions that you can subscribe to, while the my_portfolio tool returns a richer one-time snapshot that also includes account balances and working orders.
