"Capture The Flag (CTF) cybersecurity competitions and challenges" matching MCP servers:

Enables AI assistants to manage Microsoft Outlook Desktop (Classic) calendar and email through local COM automation, without Microsoft Graph or Entra registration.

An MCP-compliant server that exposes Gmail and Google Docs as tools, enabling AI agents to draft, send, and manage emails, as well as create, read, and append to documents through natural language.

An MCP server that exposes Google Docs and Gmail capabilities to LLMs via SSE transport.

Provides MCP tools for searching, reading, and drafting Gmail emails, as well as querying SAP OData endpoints with safe read operations and mock mode.

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.

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.

An MCP server that provides full email management for Yahoo Mail via IMAP, including tools to list, read, search, delete, archive, flag, and move emails, with secure OAuth authentication and support for local and remote deployments.

MCP server that gives Claude and other MCP hosts full access to Mail.app on macOS — search, read, send, reply, flag, move, and more across all accounts configured in Mail.app.

Gives Claude (or any LLM) full control over Apple Mail — read, search, compose, reply, move, flag, and delete messages — via AppleScript on your local machine, with no cloud intermediary.

One-pass agentic inbox triage as an MCP server: fetch unread Gmail → classify (action_needed/fyi/newsletter/noise) → summarize → extract tasks → draft replies as Gmail DRAFTS (never sends) → flag calendar → write a triage report. Four stdio tools (fetch_emails, save_gmail_draft, append_tasks, write_report); the host is the LLM, so it runs keyless in Claude Code. Gmail scopes: readonly + compose

An MCP server that gives AI assistants comprehensive access to Apple Mail accounts, enabling email discovery, reading, flag management, and server-side message retrieval.

Enables Claude to read, search, draft, send, flag, and move email across multiple IMAP/SMTP mailboxes while keeping credentials local.

Enables AI-driven customer support ticket processing, including classification, response generation, and automated email sending and Google Sheets logging.

Local IMAP/SMTP MCP server that lets Claude read, search, draft, send, flag, and move mail across multiple IMAP mailboxes. Credentials stay on your machine.

Expense management and Gmail receipt capture for AI assistants and automation platforms.

Enables AI assistants to securely access METU Webmail via IMAP/SMTP to list, search, read, send, reply, flag, and organize emails.

MCP server for email compatibility analysis. Analyze, preview, diff, and fix HTML emails across 15 email clients — plus capture real screenshots and create shareable links with an optional API key.

Enables AI agents to send emails and manage sending domains, templates, analytics, and content checks through the SendByte platform using the Model Context Protocol.

Gives AI agents phone numbers, email, SMS, and voice calls as MCP tools, enabling them to provision numbers, capture 2FA codes, send messages, and make calls.

Register free *.pntr.dev subdomains and manage them from your AI assistant — DNS records, wildcard DNS, disposable email inboxes, and HTTP request capture for webhook debugging. 15 tools over stdio; hosted endpoint also available.
