Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MCP de Nexus Flex: operá tu nodo/cuenta desde un asistente de IA (altas de clientes, stock, KPIs). Login por autorización web (device-flow). NO toca dinero.

Readme

nexusflex-mcp

Servidor MCP (Model Context Protocol) de Nexus Flex. Deja que un asistente de IA (Claude Desktop / Claude Code) opere tu nodo o tu cuenta de vendedor con lenguaje natural: altas de clientes, consulta de stock disponible, rentabilidad por SKU, KPIs y precios. Nunca toca dinero (facturación, cobros, cuentas, liquidaciones están bloqueados por diseño).

Uso rápido

# 1) Autorizá una vez (se abre el navegador):
npx -y nexusflex-mcp@latest login

# 2) En claude_desktop_config.json:
#   "nexusflex": { "command": "npx", "args": ["-y", "nexusflex-mcp@latest"] }

Guía completa en español: INSTALAR.md.

Cómo funciona (seguridad)

  • Login por device-flow (autorización web): el MCP pide un código, lo autorizás con un click desde la web (ya logueado), y recibe un token de vida larga, revocable guardado localmente. No se pega email/contraseña.
  • Herencia de scope: el token es un puntero opaco a tu usuario; el backend re-lee tu rol/permisos/nodo frescos en cada request. El MCP no puede hacer nada que vos no puedas desde la web. Revocar un permiso (o el token) en la app corta el acceso al instante.
  • Aislamiento en 3 capas: gating del backend (por rol + nodo/cliente) · tools por rol · denylist de dinero (en el cliente y en el backend).

Comandos

| Comando | Qué hace | |---|---| | npx nexusflex-mcp | Arranca el servidor MCP (stdio). Lo usa Claude Desktop. | | npx nexusflex-mcp login | Autoriza por device-flow y guarda el token. | | npx nexusflex-mcp logout | Borra el token local. |

Variables de entorno

| Var | Default | Descripción | |---|---|---| | NEXUSFLEX_API_URL | https://nexusflex.com.ar/api | Base de la API. | | NEXUSFLEX_MCP_ALLOW_WRITE | false | Habilita altas/ediciones (nunca dinero). | | NEXUSFLEX_MCP_ALLOW_PRECIOS | false | Habilita editar listas de precios. | | NEXUSFLEX_TOKEN | — | Token ya emitido (salta el device-flow). | | NEXUSFLEX_EMAIL / NEXUSFLEX_PASSWORD | — | Login legado por contraseña. |
