Proton Mail MCP via Bridge (IMAP/SMTP) · 13 tools · dual transport stdio + HTTP.
Connect Proton to Claude, Cursor or any other MCP client and it stops being a tab you switch to. Proton Mail MCP via Bridge (IMAP/SMTP) · 13 tools · dual transport stdio + HTTP. The proton mcp server is what makes that connection.
El agente analiza el inbox y presenta un plan de carpetas, etiquetas y alertas sin aplicar cambios. Desactiva AGENT_DRY_RUN para ejecutar.
The server ships on npm as @alexendros/protonsuite-agent, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Producto — ToolsMail — 14Pass — 4Drive — 8Calendar — stubSuite — 1Conectores — The Conectores tool exposed by this serverPlaybooks — playbooks/ — workflows predefinidos: onboarding, organize inbox, triage, fraud detection, pass audit, daily briefing, setup checklistSeguridad — The Seguridad tool exposed by this serverConfiguration is passed through the environment: MCP_TRANSPORT, PROTON_BRIDGE_USER, PROTON_BRIDGE_PASS, PROTON_MAIL_FROM, PROTON_BRIDGE_TLS_INSECURE, PROTON_PASS_ENABLED, PROTON_PASS_BRIDGE_PATH. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Proton's toolset — Producto, Mail, Pass and 6 more — is a fair guide to whether it matches your workflow. It is maintained by Alexendros; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
