Connect Claude Desktop (local)

Updated 2026-10-18

To run the server on your own machine with npx, add it to Claude Desktop's config file.

Steps

From the Claude menu open Settings → Developer → Edit Config. The file is ~/Library/Application Support/Claude/claude_desktop_config.json on macOS and %APPDATA%\Claude\claude_desktop_config.json on Windows.
Add the block below inside mcpServers. If the file already has other servers, add only the dyslexiasteps entry.
Quit Claude Desktop completely and reopen it. The server appears under the + menu in the chat box, Connectors → Manage connectors.

Configuration

claude_desktop_config.json

{
  "mcpServers": {
    "dyslexiasteps": {
      "command": "npx",
      "args": ["-y", "dyslexiasteps-mcp"]
    }
  }
}

Check it works

Ask: “Using Dyslexia Steps, how many English word lists cover kindergarten?” The answer should be 23.

If it does not connect, read the logs: ~/Library/Logs/Claude/mcp*.log on macOS, %APPDATA%\Claude\logs on Windows. Node.js must be installed (node --version).
