Install Calibration Explorer in Claude Code

What you need first

• Claude Code, installed.
• Node.js, which gives the npx command the server starts with.
• Your own values for YOUR_INPUT_ROOT,YOUR_OUTPUT_ROOT.

Steps

1. Run this in a terminal, in the project folder. It adds the server for you in that project; put --scope user after claude mcp add to have it in every project.

claude mcp add --transport stdio calibration-explorer -- npx -y @m-sanchez/[email protected] --input-root YOUR_INPUT_ROOT --output-root YOUR_OUTPUT_ROOT

2. Replace YOUR_INPUT_ROOT,YOUR_OUTPUT_ROOT with your own values.
3. Start Claude Code and type /mcp: the server is listed with its state.

Check it worked

Ask Claude Code: List the tools of calibration-explorer.

If it does not start

spawn npx ENOENT

Node.js is not on the PATH that Claude Code sees. Install it, or write the full path of npx in the config.

The server starts, but its tools fail

A YOUR_… placeholder is still in the config, or its value is wrong.
