"Latest tool requiring Google login" matching MCP connectors:

Let AI agents check whether an email is a real person's work address or a personal, disposable, relay or shared team inbox (info@, sales@, support@), and see which stack the company runs: Google Workspace or Microsoft 365 with tenant ID and identity provider. Every verdict comes with reason codes and an allow / review / block recommendation. Docs: https://isbusinessemail.com/docs/mcp

AIsa Agent MailAOAuth

one.aisa

Your agent needs a mailbox of its own — to receive, thread, draft and send, with attachments, without borrowing your personal inbox or your company's SMTP. **What you can ask for** • "Create an inbox for this agent and tell me its address." • "Read the new messages in this thread and draft a reply." • "Send this message with the attachment and wait for the response." • "Search this inbox for everything from that domain." • "Show delivery metrics and the events on this inbox." **How to use it** Point any MCP client at https://mcp.aisa.one/mail/mcp and sign in with OAuth — there is no key to create or paste. 49 tools: create and delete inboxes, list and read messages, raw message bodies, attachments, threads, drafts and draft attachments, send and reply, message search, inbox events, metrics, and list entries — reads and writes. **Why this rather than the source** A real inbox an agent owns, rather than an SMTP credential it borrows from a human. **It is also a door to the rest** The same login reaches 26 sources and 580+ operations. Find the contact elsewhere in the catalogue, then write to them from here — without adding a second server. **What it costs** Finding and inspecting an operation is free. Running one is billed per call at API prices, with no seat and no monthly minimum, and every call takes max_price_usd so an agent cannot overspend by accident. **Where else it reaches** https://mcp.aisa.one/sales/mcp finds the person to write to.

AI-powered virtual assistant that connects to Gmail, Outlook, Slack, Salesforce, HubSpot, Google Calendar, DocuSign, QuickBooks, and 20+ other services. Manage your entire professional life through a single Claude conversation — email, calendar, CRM, documents, travel, expenses, and more.

AgentiSend is a transactional email API: send through verified domains with a message log, budgets, a preflight and refusals that name the fix; built so AI agents can send on your behalf. The hosted MCP server at https://api.agentisend.com/mcp exposes 82 tools (44 on tools/list; the rest via list_more_tools). A send is one message or a batch of up to 500 items with per-item results. preflight_email runs every gate a real send runs, sends nothing, and costs nothing. Every 4xx returns code, message, and fix. There is no tool for unsolicited mail. Auth is a bearer API key or OAuth 2.1 with dynamic client registration. Starter prompts: "Send this receipt to the customer." "Preflight this send and tell me what would stop it." "What can I spend today?"

Phone, SMS & email for AI agents — one remote MCP endpoint, OAuth login, zero install.
