Why pair Cursor with CrossTrade MCP
Cursor sees your project files and refactors across them. CrossTrade adds the part Cursor cannot do on its own: it lets the agent inspect your real NT8 install, compile against it, and drive Strategy Analyzer. The pair turns vibe coding into a verified compile-backtest loop.
.cursor/mcp.json with mcpServers, native browser OAuth (callback cursor://anysphere.cursor-mcp/oauth/callback) What this combination unlocks
Multi-file refactor
Apply a spec change across every strategy in your workspace at once.
Native OAuth
Browser handles consent; token caches automatically.
Cursor Composer
Plan a multi-step compile workflow before any tool call.
The connection chain
Cursor │ OAuth-authorized tool call ▼ CrossTrade hosted MCP server (https://app.crosstrade.io/v1/api/mcp) │ ▼ CrossTrade Add-On running inside NT8 on your PC │ ▼ NinjaTrader 8
One URL, one consent screen, one read-only first prompt. The MCP server is hosted by CrossTrade; you don't run anything beyond NT8 + the CrossTrade Add-On.

Common questions
Is Cursor a good fit for NinjaScript development?
Yes — Cursor's strength is multi-file editor context plus a chat panel that can call MCP tools. CrossTrade adds what Cursor can't do alone: inspect your real NT8 install, compile NinjaScript against it, run Strategy Analyzer. The pair turns vibe coding into a verified compile-backtest loop.
Do I need Cursor, or does Claude Code / Cline / Continue work?
Cursor for multi-file IDE work (the typical NinjaScript project). Claude Code for terminal-first compile loops. Cline / Continue / Roo Code if you're staying in VS Code. Same CrossTrade tool surface for all of them; pick the editor you already use.
Pricing?
Hobby (free), Individual ($20/mo), Teams ($40/user/mo), Enterprise (custom). MCP support is on all tiers. Paid plans get more frontier-model usage; BYOK works across tiers.
Mac, Windows, and Linux?
All three. Cursor is a standalone fork of VS Code, downloaded from cursor.com.
Cursor vs Windsurf?
Both are AI-native IDE forks. Cursor has a longer track record and broader ecosystem. Windsurf's Cascade agent is built around multi-step planning (give one goal, let it plan the steps). Both support remote MCP via similar JSON configs; CrossTrade works in both.
Composer or chat?
Use Composer (⌘K) for single-shot "do this then that" instructions. Use chat for back-and-forth refinement. The CrossTrade tool calls work the same way from either — the agent sees the same tool surface.
How do I avoid the SSE fallback hanging?
Cursor's auto-fallback from Streamable HTTP to SSE has known bugs for some servers. CrossTrade serves Streamable HTTP natively, so the fallback shouldn't trigger. If you see hangs, restart Cursor and check that the server URL doesn't accidentally have "sse" in the path.
Static bearer token instead of OAuth?
Yes — put it in the headers field, not the auth field. The auth field expects an OAuth Dynamic Client Registration shape; a bare Bearer token there will silently fail. Use { "headers": { "Authorization": "Bearer YOUR_TOKEN" } } for static auth.
