Proton Mail Mcp

authSTDIOregistry active
Summary

Connects Claude to Proton Mail via the local Bridge client, exposing 13 tools over IMAP and SMTP. You get read ops (list folders, search with filters, fetch full messages and attachments up to 50MB), writes (send with threading headers, move, flag, delete), and folder management. Runs dual transport: stdio for local CLI work, HTTP with bearer auth and rate limiting for remote clients like Routines. The crypto boundary stays at Bridge on your machine, so end-to-end encryption holds and nothing leaks plaintext to third parties. Ships with connection pooling, retry logic, and a full CI suite. Reach for this when you need Claude to manage a privacy-focused inbox without OAuth handoffs to SaaS providers.

Propósito de este documento

  • Objetivos: Orientar el pulso del repo, el quickstart y el enrutado a los documentos canónicos.
  • Estructura: Ficha → pulso → mapa de lectura → instalación, tools, agente, calidad.
  • Contenido a integrar según contexto: Stack TypeScript/MCP, frontera Bridge, dry-run por defecto, Makefile fachada.

Propósito

Punto de entrada de lectura. Te dice el pulso, cómo arrancar y qué documento abrir después. Lo no negociable vive en CONSTITUTION.md.


Estado en una mirada

Pulso: 24 de septiembre de 2026 · v1.4.0

Fase activa: Fase 1 (Pass / agente / DX) checklist cerrada · siguiente: Fase 2 (Calendar, bloqueada). Ver ROADMAP.md.

Métricas: 47 tools por defecto (50 con Calendar experimental) · 965 tests · cobertura ~98% (gate 95%).

CapaEstado
Mail (Bridge IMAP/SMTP)Operativo
Pass (pass / gopass)Operativo
Drive (proton-drive CLI)Operativo (ADR-006)
CalendarStub hasta CalDAV en Bridge (ADR-005)
Documentación canónicaSubfase 0 completada

MCP server multi-producto para Proton Suite: Mail, Pass, Drive y Calendar (stub). Un agente opera el buzón, gestiona contraseñas y sincroniza archivos — local, sin exfiltrar contenido E2E.

ModoDescripción
stdio (default)Sin exponer red. Ideal para agentes IA locales.
streamable HTTPBearer auth + origin allowlist. Docker / reverse proxy.

Quickstart

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

1. Instalar y compilar

git clone https://github.com/Soluciones-Alexendros/protonsuite-tools.git
cd protonsuite-tools
pnpm install && pnpm build && pnpm 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 pnpm exec protonsuite-agent organize
# o: npx -y @alexendros/protonsuite-agent organize

El agente analiza el inbox y presenta un plan sin aplicar cambios. Desactiva AGENT_DRY_RUN solo tras revisión.


Tools MCP

47 tools por defecto (50 con Calendar experimental). Lectura: response_format: "markdown" | "json".

  -O /usr/local/bin/proton-drive && sudo chmod +x /usr/local/bin/proton-drive
proton-drive auth login

Requiere DRIVE_ENABLED=true (default). Ver docs/drive-audit.md.


Despliegue

docker compose up -d

Ver docs/deployment-http-docker.md. Instalador: scripts/install.sh.

Interfaz local

SPA estática en apps/web (ADR-0007): landing y panel de estado. No forma parte del proceso MCP. pnpm run build la genera en apps/web/dist. Se abre sin Bridge; el panel usa el adaptador local «datos de ejemplo» y no pide credenciales. Calendar sigue en stub.

Calidad

Fachada canónica (Makefile): make lint, make test, make smoke, make validate.

make validate        # lint + typecheck + test + build + smoke
pnpm run typecheck   # TypeScript strict
pnpm test            # Vitest (953+)
pnpm run coverage    # Coverage v8 — gate 95%, objetivo ≥98%
pnpm run build       # tsc → dist/ y SPA apps/web (tokens, contraste, vite)
pnpm run smoke       # stdio initialize + tools/list
pnpm run knip        # Unused deps/exports
pnpm docs:check      # mcp-tools.md en sync

Seguridad (resumen)

  • Bearer timing-safe, origin allowlist, rate-limit 120/min/token.
  • HTTP per-session; idle eviction 30 min.
  • Pass nunca expone valores — solo {found: true}.
  • Dry-run por defecto en el agente (CONSTITUTION.md §4).
