"An MCP that effectively manages other MCPs" 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.

A collection of small MCP servers for macOS automation that expose Apple Mail, MoneyMoney, and Spotlight functionality as tools via AppleScript and command-line, enabling AI applications to search mail, manage contacts and transactions, and perform system-wide file searches through natural language.

Model Context Protocol servers for Microsoft 365, enabling AI assistants to interact with Calendar, Contacts, OneDrive, Outlook, and SharePoint via the Microsoft Graph API.

MCP server for Yahoo Mail over IMAP+SMTP that enables AI assistants to manage emails fully—listing, reading, searching, threading, flagging, moving, archiving, handling attachments, and sending/reply/forward/draft—using an app-specific password.

Enables AI assistants to manage Zoho Mail accounts, including sending/receiving emails, folder and label management, organization administration, and productivity tools like tasks and notes.

MCP server that sends mail over SMTP, gated behind an allowlist and a human confirmation

An MCP server that exposes a local notmuch email database to an LLM client such as Claude. It is read-first: searching, reading, and understanding mail is always available; writing anything (drafts, tags, exported files) requires an explicit opt-in flag and is confined to clearly bounded locations.

An email MCP server that lets Claude or any MCP client search, read and draft mail via IMAP, treating every message as untrusted input. It prioritizes safety with plain-text-only bodies, disabled sending until an allowlist is set, and no bcc support.

Giggal.ai is an email verification tool that runs a deep mailbox existence check on every address and verifies catch-all/accept-all and even SEG protected emails. Your bounce rate stays under 5%, and the 30% of every B2B list that other tools flag as "Risky" becomes deliverable again.

Local-first Microsoft Outlook MCP server: a single Go binary that manages calendar events and mail through the Microsoft Graph API over stdio, with tokens stored in the OS keychain and no Entra ID app registration required. Exposes four aggregate tools (calendar, mail, account, system) dispatched by an operation verb, with multi-account support and read-only and mail-gating modes.

An MCP server that exposes a verify_email tool for checking email syntax, disposable domains, and MX records, returning a structured validity result.

An MCP server that enables AI assistants to read and search Proton Mail messages through a locally running Proton Mail Bridge. It provides tools like list_folders, list_messages, search_messages, get_message, and get_attachment.

MCP server for disposable email. Gives an assistant its own throwaway inbox, then hands back the confirmation code out of the message that arrives.

An MCP server that provides programmatic access to Apple Mail, enabling AI assistants like Claude to read, send, search, and manage emails on macOS.

Enables AI agents to publish static sites and build folders as live websites, push updates, provision and manage custom domains with DNS, and send transactional email. Ships as a local pip/uvx server that reads build folders directly, or as a hosted HTTP endpoint for Claude Code, Claude Desktop, and other MCP clients.

MCP server that gives an AI assistant simultaneous access to multiple Gmail accounts with per-account read-only, draft, or send tiers, two-phase write confirmation, and safeguards for handling untrusted email content.

An MCP server that provides 49 tools to access Microsoft Outlook for Mac, enabling management of mail, calendar, contacts, tasks, and notes via AppleScript.

An MCP server for the PostStack email API that enables AI assistants to send transactional emails, manage contacts, handle inbound email threads, and perform deliverability checks through 84 curated tools.

An MCP server that interfaces with the Missive API, enabling Claude to manage email conversations, contacts, and team collaboration.

An unofficial MCP server for Smartlead that exposes the SmartProspect API and core Smartlead operations, enabling agents to search for leads, manage campaigns, and control credit spending with configurable safety modes.
