"Super User" matching MCP servers:

Multi-user Gmail MCP server that enables sending/receiving emails, managing accounts, and searching mail via SMTP/IMAP with per-user isolation and encrypted app passwords.

Enables AI assistants to seamlessly interact with Microsoft 365 services through the Graph API, featuring super tools, unified search, and intelligent learning.

This MCP server provides comprehensive Google Workspace integration (Gmail, Drive, etc.) with multi-user OAuth. Unique features include RAG-powered natural language to Chat card rendering, runtime Jinja2 macro creation, and dynamic tool management.

Enables AI agents to search, read, label, draft, and reversibly trash Gmail messages through the official Gmail API, with safe attachment handling and guardrails against prompt injection. Drafts can be sent only after explicit user confirmation for that exact draft, and nothing is permanently deleted.

A minimal MCP server for sending plain-text emails and managing Gmail user labels over stdio, using only gmail.send and gmail.labels OAuth scopes.

Enables AI apps to securely read, search, organize, draft, attach files to, and send email across up to five self-hosted IMAP/SMTP mailboxes, with sending only after explicit user approval.

Read and write email through the Atomic Mail from an AI agent. Handles proof-of-work authentication and JMAP so the agent thinks in JMAP method calls. Use when the user asks to register an email inbox, list mailboxes, fetch or send email.

Enables MCP clients to manage multiple IMAP/SMTP mailboxes by listing folders, searching and reading messages, preparing Markdown drafts and replies, and sending only a draft the user has reviewed and confirmed.

Gives AI assistants stdio access to a Microsoft Exchange/OWA mailbox so they can check unread mail, search messages, read and summarize threads, look up senders and organizational contacts, and send or reply to email only after the user approves the message in a local browser window.

Provides read-only search and retrieval of archived emails, archive statistics, health, and ingestion sources, with an optional administrative toolset for user, role, reindexing, and queue management.

Manages email accounts via IMAP/SMTP, enabling reading, searching, sending, replying, forwarding, and folder management with multi-user and OAuth support.

Enables agents to list, search, and read mailbox messages, manage user-isolated local drafts, fetch attachments, and send or reply to email through a dedicated mailbox user's HTTPS API. Write operations such as sending, replying, and marking messages read stay disabled until explicitly enabled and authorized.

Enables AI agents to access Microsoft Outlook mail and calendar, plus read-only Microsoft Teams message history, acting as the signed-in user via delegated permissions.

Enables MCP-compatible AI clients to securely read a user's Microsoft 365 data across Outlook, Calendar, Teams, meetings, OneNote, SharePoint, OneDrive, Loop, and Search, and to send Outlook email only after explicit user confirmation.

Lets AI agents connect a user's database, draft marketing campaigns in their brand, preview emails, and send tests while the user retains final send control.

Enables AI assistants to read, search, draft, and send email with attachments over IMAP/SMTP, keeping passwords in the OS keyring and gating outgoing mail on user approval for CMMC Level 2 environments.

Enables sending emails via Amazon SES, SMS/MMS/RCS messages through AWS End User Messaging, and sharing files via CloudFront-signed download links, all from AI assistants like Claude Code or Claude Desktop.

Enables natural language control over Google Workspace (Gmail, Drive, Calendar, Sheets, Slides, Tasks) through secure OAuth 2.1 authentication, with vault-level security and multi-user isolation.

Enables AI clients to work with IMAP mail accounts over a Streamable HTTP MCP endpoint, with per-user login-key authentication, isolated account directories, and encrypted (write-only) credential storage behind a self-hosted gateway.

Enables an AI agent to send or draft email as the signed-in user through Microsoft Graph, including multiple recipients, HTML or plain-text bodies, and file attachments. Uses delegated least-privilege PKCE authentication so messages can be staged as drafts for approval or sent directly.
