How to Use the ISO New England MCP in Cursor

Q: How do I add the ISO New England MCP server to my Cursor project?

Create a .cursor/mcp.json file in your project root and define the server. Once saved, your agent will immediately gain access to the grid tools during your coding chat.

Q: Can the Cursor agent use ISO New England data to write test suites?

Yes, your agent can call getfuelmix or getlmp to fetch live MCP payloads and generate accurate unit tests. This eliminates the need to manually write mock JSON responses.

Q: Does the ISO New England MCP server work in Cursor's Agent mode?

Absolutely, Agent mode allows the editor to run tools like getsystemload autonomously. It will fetch the current megawatt usage and write it directly into your active files.

Q: Can I track electricity imports and exports?

Yes, use getactualinterchange to see net power flows between New England and adjacent grids. This tool returns real-time megawatt values for external ties.

Build energy apps and run grid calculations with live ISO New England market data directly in Cursor.

Inject live energy prices into your Cursor workspace

The `get_lmp` tool pulls live locational marginal pricing directly into your active coding session. Your agent writes code that handles real-time dollar-per-megawatt-hour values instead of relying on static mock data. If you need to build forecasting models, `get_day_ahead_lmp` lets your editor reference tomorrow's expected prices. This ensures your code works with actual market conditions from day one.

Monitor grid stability via this Cursor MCP Server

The `get_regulation` tool exposes current clearing prices and capacity requirements for grid stabilization. Your agent uses these metrics to write automated dispatch logic. Combine this with `get_reserve` to audit regional operating reserve requirements during peak hours. You get direct access to raw grid stability metrics without leaving your codebase.

Track regional load patterns as you write code

The `get_system_load` tool delivers real-time megawatt consumption data straight to your compiler. Your agent reads this current demand to test how your software responds to grid stress. Analyze historical trends by calling `get_hourly_load` to verify how your application handles seasonal consumption shifts. This puts real-world utility performance directly in your terminal.

Setup guide

Set up ISO New England MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the ISO New England MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent ISO New England transactions." If the MCP tools are loaded correctly, Cursor will call the ISO New England tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "iso-new-england-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
