Install @rolemodel/optics-mcp in LM Studio

What you need first

• LM Studio, installed.
• Node.js, which gives the npx command the server starts with.

Steps

1. In LM Studio, open the Program tab and choose Install › Edit mcp.json.
2. Add this block. If the file already has mcpServers, add only the entry inside it.

{
  "mcpServers": {
    "optics-mcp-7fcd1r": {
      "command": "npx",
      "args": ["-y", "@rolemodel/optics-mcp"]
    }
  }
}

3. Save the file and restart LM Studio.

Check it worked

Ask LM Studio: List the tools of optics-mcp-7fcd1r.

If it does not start

spawn npx ENOENT

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

Nothing changes after a restart

The file is not valid JSON any more. Look for a missing comma where the block was added.
