The problem
Your AI only sees one account.
You live across many.
Claude and ChatGPT connect to one Gmail at a time. But you run several ventures, a personal inbox, a couple of Outlook tenants. So your AI is half-blind — it can't search across them, can't tell you when you're actually free, can't send from the right identity. Switchboard hands it all of them.
Connects with
Every account you have.
One connection.
Mail, calendars, and files across Google and Microsoft — plus your WhatsApp and LinkedIn messages — through a single MCP. Connect an account once and your AI can reach it everywhere.
Direct API access — fast, exact, nothing scraped.
What it does
Not just a unified inbox
Real availability
"When am I free?" answered across all your Google and Outlook calendars — the one thing a single-account tool can't do.
Awaiting reply
Every thread where the ball's in your court — or where you're still waiting on them — across email, WhatsApp, and LinkedIn, with how long it's been, ready to follow up.
Files, everywhere
Search and pull files across every Drive and OneDrive you have, from one place.
The right account
Reply and send from the correct identity automatically — matched by domain or by who you've talked to before.
Scheduled send
Queue any message — email or chat — to land at the right moment, on any account. Reviewed and approved by you before it ever goes out.
Beyond email
Read, search, and reply to your WhatsApp and LinkedIn messages — and start new conversations — right alongside your mail.
LinkedIn, working for you
Find people by company or industry, see who owes a reply and who's gone quiet, reply in-thread, read a profile's current company, accept or send invites — your whole pipeline, not just search.
Cross-platform drafts
Draft replies with the quoted history intact, sitting ready for your review — even on WhatsApp and LinkedIn, which have no native drafts. Switchboard holds them until you approve.
Acting, not just reading
Your follow-ups, run for you.
Connect your accounts and your AI can run the whole outreach loop — including WhatsApp and LinkedIn, the channels other tools can't touch. It surfaces who owes a reply, drafts the next message in your voice, and sends on your OK — on a schedule, or the moment someone replies. You stay in approval the whole way.
Knows who's due
Who replied and is waiting on you, and who's gone quiet on a follow-up — across email, WhatsApp, and LinkedIn, in a single pass, with how long it's been.
Drafts in your voice
The right next message, written the way you write — shown for your approval before anything sends. No re-pitching people who already know you.
Never double-messages
It checks the live thread at the moment of sending, so it won't reply to someone who already answered or nudge the same person twice.
1
Connect
Sign in once and link your accounts — Gmail and Outlook. No Cloud Console, no config files.
2
Point your AI at it
One connection in Claude or ChatGPT (or any MCP client) and your AI can read, search, and draft across everything.

It acts — you approve
Triage, schedule, draft follow-ups. Sends and invites only go out when you say so — never on its own.
Add it to your AI
After you've signed in and linked accounts, add this MCP server in Claude (Settings → Connectors → Add custom connector) or ChatGPT (Settings → Connectors):

Trust
Your accounts. Your control.
OAuth only — we never see your password. Tokens are encrypted at rest, message bodies are never stored, and each account is isolated to you. Nothing is sent without your explicit approval. Built by Thalassis, the same team behind mission-critical platforms in aviation, energy, and finance.
