Install & config

Copy the command above
Paste it as one entry under mcpServers in claude_desktop_config.json — local servers take command + args (example: clients)
Restart your client

Client config (built from the install command this repo gives)

{
  "mcpServers": {
    "formulahendry-mcp-server-code-runner": {
      "command": "npx",
      "args": ["-y", "mcp-server-code-runner@latest"]
    }
  }
}

Parsed from the README we fetched on 2026-11-07; we have not executed it.

command/args come from the install command the repository states. When it is ambiguous, the project README wins.

VS Code (.vscode/mcp.json - the key is servers)

{
  "servers": {
    "formulahendry-mcp-server-code-runner": {
      "command": "npx",
      "args": ["-y", "mcp-server-code-runner@latest"]
    }
  }
}

Same server, but VS Code keeps it under <code>servers</code>.

Claude Code (command line)

claude mcp add --transport stdio formulahendry-mcp-server-code-runner -- npx -y mcp-server-code-runner@latest

Claude Code does not read a config file; add the server with this command.
