Connecting from Cursor

Cursor supports MCP and lets you use the ELN server with GPT, Gemini, Claude, or any other model offered in its Agent mode. The tools behave identically across models — pick the model from Cursor’s Agent dropdown without changing anything in the MCP setup.

Prerequisites

Cursor installed
E-Lab Notebook installed; see the MCP server overview for the location of ELNMCPServer.exe

Registering the Server

Create or edit mcp.json in one of two locations:

Global: %USERPROFILE%\.cursor\mcp.json — available in every project
Project: .cursor\mcp.json in the repository root — overrides the global entry of the same name

Add an eln entry under mcpServers:

{
  "mcpServers": {
    "eln": {
      "type": "stdio",
      "command": "C:\\Program Files (x86)\\E-LabNotebook3\\ELNMCPServer.exe"
    }
  }
}

Verifying Registration

Open Settings (Ctrl+Shift+J) → Features → Model Context Protocol. The eln server should appear in the list with its tools enumerated; toggle it on if it isn’t already. If the server fails to start, open the Output panel (Ctrl+Shift+U) and select MCP Logs from the dropdown to see startup errors.
