Connect Your AI Agent

The NinjaTrader MCP server is a remote server you connect to over HTTPS. There’s nothing to install. You add the server URL to your AI client, then authorize it with your NinjaTrader account through OAuth. After that, your agent can use the available tools.

Server URLs

The beta runs on Demo, which trades simulated money. Each URL hosts a single environment with its own accounts.

The server uses the Streamable HTTP MCP transport. When your client first connects, it discovers the NinjaTrader authorization server automatically and walks you through signing in. See Authentication & Access for what happens during that step.

Connect by platform

The following are AI clients that work with the NinjaTrader MCP server. Use the Demo URL in the steps below while testing. Where your client asks you to name the server, use ninjatrader-demo. The trading-skills plugin declares that same name in its manifests. The trading skills name every tool without a prefix, so any server name works. Matching the plugin name avoids a second registration for the same server.

Other platforms

You can connect from any AI client that supports remote MCP servers with OAuth. Add the Demo URL, https://mcp-demo.tradovateapi.com/mcp, wherever your client accepts a Streamable HTTP MCP server. Complete the sign-in when prompted.

Authorize your account

The first time your client connects, it redirects you to sign in to NinjaTrader and approve the connection. This uses OAuth. Your agent never sees your password. You must complete authorization in a desktop browser.

After you approve, the client stores a session and your agent can start calling tools. Sessions expire after a period of inactivity. If your agent stops working, reconnect to start a new session. See Authentication & Access for the full flow and session details.

Verify the connection

Once connected, confirm the server is working with a read-only prompt before doing anything else:

List my NinjaTrader accounts and show my current positions and working orders.

This calls the read-only my_portfolio tool. If your agent returns your accounts, you’re connected. From there, see the Tools reference for everything your agent can do.
