"An overview or resources on Kubernetes" matching MCP servers:

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 querying and retrieving email messages from an IMAP mailbox via MCP tools, with an indexed storage backend on Cloudflare.

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.

Gives an agent (like Claude) complete control over a Gmail or Google Workspace account via IMAP/SMTP using an app password, without needing OAuth.

Enables sending transactional emails with text or HTML body, delivery status, and message ID via Resend. Pay-per-call using x402 micropayments (USDC on Base L2), no API key or signup required.

Enables sending single or batch emails via the Postmark API through an MCP server.

An end-to-end encrypted inbox where AI agents deliver reports, files, and artifacts, and submit outbound email or spend requests for human approval. Content is decrypted in the browser, never on the server.

MCP server that exposes an email verification tool, returning verdicts of valid, invalid, or risky with reasons.

Enables pushing enriched leads into Instantly or Smartlead campaigns with ICP score gating, deduplication, and dry-run previews via an Apify actor.

Reads and searches local email archives (.mbox or .eml) with full MIME parsing, enabling queries about senders, subjects, dates, and bodies while keeping all data on your machine.

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.

Renders markdown into email-safe HTML that holds up in Outlook and Gmail, lints drafts for deliverability problems, and returns a live preview link. Also serves the emailmd syntax reference so an assistant can look up directives on demand.

An MCP server for Microsoft Graph, exposing 60 tools across calendar, email, meetings, Teams chat, files, people, directory, tasks, and OneNote over stdio or Streamable HTTP.

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

MCP server that gives an agent its own email inbox: it opens the inbox, waits for the one-time code a signup sends, and reads or sends mail. Addresses are permanent, so a test suite does not need a new one per run; only the messages expire, on a retention window you set.

An MCP server that enables LLMs to search, fetch, and act on Google Workspace (Drive, Gmail, Docs, Sheets, etc.) with rich, one-call results and file deposits to disk, reducing context usage.

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.

Enables email address verification through a single MCP tool, returning whether an address is valid, invalid, or risky.
