Proton Suite Agent

MCP server multi-producto para Proton Suite: Mail (Bridge IMAP/SMTP), Pass (pass-cli), Drive (CLI oficial) y Calendar (CalDAV stub). Un agente puede operar el buzón, gestionar contraseñas, sincronizar archivos y clasificar correo — todo sin salir de tu máquina.

Modo	Descripción
stdio (default)	Sin exponer nada a la red. Ideal para agentes IA locales.
streamable HTTP	Bearer auth + origin allowlist. Para despliegue con Docker.

Quickstart

Prerrequisitos: Node ≥ 22, Proton Mail Bridge corriendo en local, pass + gpg para contraseñas.

1. Instalar y compilar

git clone https://github.com/Iniciativas-Alexendros/agent-protonsuite.git
cd agent-protonsuite
npm install && npm run build && npm run smoke

2. Configurar variables de entorno

export PROTON_BRIDGE_USER=you@proton.me
export PROTON_BRIDGE_PASS=your-bridge-password
export PROTON_MAIL_FROM=you@proton.me

3. Conectar tu cliente MCP

{
  "mcpServers": {
    "protonsuite": {
      "command": "npx",
      "args": ["-y", "@alexendros/protonsuite-agent", "protonsuite-mcp"],
      "env": {
        "MCP_TRANSPORT": "stdio",
        "PROTON_BRIDGE_USER": "you@proton.me",
        "PROTON_BRIDGE_PASS": "your-bridge-password",
        "PROTON_MAIL_FROM": "you@proton.me",
        "PROTON_BRIDGE_TLS_INSECURE": "true",
        "PROTON_PASS_ENABLED": "true",
      },
    },
  },
}

Seguridad: usa PROTON_PASS_BRIDGE_PATH=proton/bridge/password o el wrapper JIT en connectors/stdio-wrapper.sh.example para no dejar el bridge password en disco.

4. Organizar el buzón (dry-run)

AGENT_DRY_RUN=true npx -y @alexendros/protonsuite-agent organize

El agente analiza el inbox y presenta un plan de carpetas, etiquetas y alertas sin aplicar cambios. Desactiva AGENT_DRY_RUN para ejecutar.
