"A database that can be operated or managed" matching MCP servers:

Enables AI agents to analyze whether they should send an email, evaluating passive aggression and regret probability with a recommendation heavily weighted toward no.

Enables AI assistants to interact with Microsoft 365 and Office services through the Microsoft Graph API, providing tools for email, calendar, files, Teams, SharePoint, and more with configurable permissions and output formats.

Enables AI agents to send emails, create drafts in Gmail, and append content to Google Docs via standardized MCP tools.

A stdio MCP server exposing a validate_emails tool that lets agents screen email lists without sending mail or probing SMTP, checking syntax, DNS/MX records, disposable domains, role accounts, free providers, typo suggestions, and SPF/DMARC. Each address comes back with a valid/risky/invalid/unknown verdict plus machine-readable reason codes so agents can clean leads and signups before outreach or import.

Enables MCP clients to read and search Proton Mail and create draft-only emails with attachments through the local Proton Mail Bridge, while requiring out-of-band human approval before a draft can be committed.

Gives an AI assistant read- and draft-only access to a single personal Microsoft mailbox, letting it search, list and read mail, browse folders, save attachments to a jailed directory, and create new or reply drafts. It requests no send scope, so mail can never be sent, deleted, moved or marked, and calendar, contacts and files are untouched.

Enables AI agents to list, read and download the files attached to Gmail messages, extracting text from PDFs, Word, Excel, PowerPoint and plain-text files straight into context or saving them to disk. It runs locally with read-only Gmail access, so attachments can be summarised, checked or analysed without leaving the chat.

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.

Enables MCP-enabled AI clients to access Microsoft 365 operated by 21Vianet (China) through Microsoft Graph, supporting email, calendar, OneDrive, SharePoint, Teams, contacts, search, and intelligent aggregation with delegated permissions and OAuth 2.1.

Give Claude (or any MCP client) a real email inbox and SMS. Your AI agent can read and send email, manage inboxes, track delivery, and handle SMS.

Enables AI assistants to read, search, organize, and send email in a Viettel mailbox using built-in IMAP/SMTP server settings and encrypted credential storage. Supports optional read-only mode or a custom allowlist to restrict which mailbox tools an assistant can use.

Enables controlled Microsoft 365 mail workflows including search, read, thread, attachment, and managed draft operations through Microsoft Graph, without sending or modifying messages.

Enables remote-only interaction with the mailery.co hosted HTTPS API via CLI, MCP, and SDK, without running a local mail server or accessing a database/provider account.

Exposes read-only Milo mailbox tools for searching and reading email, plus a read/write bridge to Airtable's official remote MCP server for record operations gated by explicit read or write permissions. Each configured connection gets its own tool prefix, so multiple mailboxes and Airbase resources can be served from one process with private credentials supplied outside the code.

Mu is an MCP server and web app that provides agents and humans access to real-world services like news, web search, mail, markets, weather, video, places, images, files, calendar, and contacts. It offers a wide range of tools and can be self-hosted or used live at micro.mu.

An MCP server that gives AI agents structured access to a Microsoft Outlook mailbox through the Microsoft Graph API, with a deliberate constraint: agents can read and draft emails, but only humans can send.

Enables LLM and MCP clients to read and manage iCloud calendars, contacts, mail, and notes, including creating, updating, deleting, and sending items. It also supports inbox rules and can be used through Home Assistant's LLM API or MCP endpoint.

Enables AI agents to read, search, send, reply to, forward, organize, and delete Yandex Mail messages through IMAP/SMTP tools, including drafts, labels, folders, attachments, and Cyrillic search. It can run locally in Docker or be deployed to Cloud.ru with environment-based configuration.

Enables AI assistants to read, search, send, and organize Fastmail email, contacts, and calendar data through the JMAP and CalDAV APIs, covering attachments, drafts, threading, labels, bulk operations, and event management. Includes a packaged Desktop Extension so it can be installed directly into Claude Desktop.

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.

Enables MCP clients to search, read, and inspect Apple Mail on macOS, including conversations and attachments. It can create new, reply, reply-all, or forward drafts, but cannot send or modify existing messages.

Enables an agent that reads a person's inbox to check a raw or .eml message and receive a 0-100 cold-outreach score with the reasons behind it. The agent can then avoid replying on the person's behalf to a cold message, or surface a likely cold one with its signals for the person to judge.

Enables AI assistants to manage email over IMAP and SMTP: search, read, send, reply, forward, move, mark, bulk-delete, and browse folders across multiple mailboxes at once. Credentials are stored with AES-256 encryption and can be injected at runtime from environment variables, with connection pooling and a web setup wizard covering 15+ providers.

Enables Claude to read and search mail in local Outlook classic via COM, and to create new draft, reply, and reply-all drafts for the user to review and send. It exposes no send, delete, or move capability, so messages can only be examined and drafted.

An MCP gateway that lets AI clients act as the signed-in user against 21Vianet-operated Microsoft 365 through Microsoft Graph China, enabling mail reading and sending, calendar scheduling and conflict checks, and OneDrive/SharePoint file search. It preserves tenant-granted permissions with delegated access, role and scope filtering, write confirmations, and audited operations.

A self-hosted remote server that connects an existing mailbox to any MCP client by URL with account sign-in, so an agent can send, draft, read and follow up on email. It supports attachments, reply tracking, rescuing replies from spam and quarantine, delivery status and contacts, via either mailcow's native login with automatic scoped app passwords or generic IMAP/SMTP credentials.

Enables MCP-capable AI clients to use a 21Vianet-operated Microsoft 365 tenant on the user's behalf — reading mail, analyzing calendar conflicts, searching OneDrive and SharePoint files, and sending messages after confirmation — through a single Streamable HTTP endpoint with OAuth and delegated Microsoft Graph China permissions. Respects existing tenant roles, scopes, and audit boundaries, so access never exceeds what the signed-in user already has.

This MCP server enables AI assistants to securely access and manage a NetEase mailbox through IMAP/SMTP, supporting operations like listing folders, searching and reading emails, sending drafts, and moving messages. It can be used locally via stdio or remotely via HTTP with API key authentication.

Enables MCP-capable AI clients to read and act on a user's 21Vianet-operated Microsoft 365 mail, calendar, OneDrive, SharePoint, Teams, contacts, and search data as that signed-in user through Microsoft Graph China. Access is bounded by delegated permissions, App Roles, write confirmation, and audit controls.

Connects Claude to any IMAP/SMTP mailbox so it can list folders, read and search messages, fetch attachments, and create or send drafts, with read/draft/send permission modes and built-in OAuth. Designed for mail hosts that lack a native Claude connector.
