Connecting from Claude Code

Claude Code is Anthropic’s official CLI for Claude. Once registered, the ELN MCP server is launched automatically whenever Claude Code needs its tools — no other configuration required.

Prerequisites

  • Claude Code installed and authenticated (claude --version should print a version)
  • E-Lab Notebook installed; see the MCP server overview for the location of ELNMCPServer.exe

Registering the Server

Run this command in any terminal:

claude mcp add -s user eln -- "C:\Program Files (x86)\E-LabNotebook3\ELNMCPServer.exe"

This registers the server globally (for all projects) under the name eln. Claude Code will start the executable on demand and present its tools during conversations.

Verifying Registration

Run claude mcp list to confirm the server is registered. You should see an entry like:

eln: C:\Program Files (x86)\E-LabNotebook3\ELNMCPServer.exe (user)

The first time you ask Claude Code to query the notebook, it will start the server in the background and surface the available tools.
