"Understanding Frontend and Backend Development" matching MCP servers:

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

Enables AI agents to inspect any public domain’s web technology stack, email deliverability and DNS health (MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI), and HTTPS security posture with typed JSON scores and remediation-ready findings, plus history, bulk checks, monitoring alerts, and reverse technology lookups.

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.

Send email, find out why an email failed, set up sending domains, and manage templates, contacts, lists and campaigns in your AhaSend account.

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.

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

Enables querying a structured CV and sending test emails via Ethereal through a backend API.

Self-hosted Gmail gateway MCP server that enables searching and fetching emails from multiple authorized Gmail mailboxes via a single backend authorization boundary.

A production-grade backend that lets LLMs safely operate Gmail, Google Drive, and Calendar through the Model Context Protocol.

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

MCP server that exposes Gmail and SAP tools, enabling natural-language email management and SAP data browsing through a Mistral-powered AI assistant.

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 AI agents to send emails and manage tasks in Microsoft To Do with scoped, low-risk access to Microsoft Graph.

Fetch fresh leads and verify emails in one MCP server

MCP server that enables AI agents to check if email addresses or domains are disposable using the isitdisposable.com API. It provides tools like check_email, check_domain, and check_batch for real-time validation.

Detects whether a company runs cold email outbound and identifies the email sending infrastructure, including sending domains, platforms, and authentication status.

Provides email validation and domain configuration auditing tools for AI assistants, enabling single address checks, bulk list cleaning, SPF verification, and full mail setup grading (A-F) with actionable fixes.

A self-hosted MCP server that provides secure access to iCloud Mail, Calendar, and Contacts, enabling agents to read and send email, manage calendar events, and search contacts with safety controls like approval for outgoing messages.

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

Enables read-only access to a single Gmail mailbox, listing emails within a date range and retrieving full headers and body text of individual emails, with deep-link jump URLs for each result.

Enables auditing emails for internal contradictions and reporting detected incoherences with literal textual evidence, without issuing a phishing verdict.

Enables managing multiple Gmail accounts under one OAuth client, with per-account access levels, cross-account search, and read/write operations via stdio or Streamable HTTP.

Enables AI agents to send emails via Microsoft 365/Office 365 using app-only authentication and Microsoft Graph API, supporting HTML content, attachments, and CC/BCC.

Enables verification of email address lists through a chosen third-party service (ZeroBounce, NeverBounce, MillionVerifier, BounceBan, or Reoon), returning one normalized row per address with verdict and role, free, and disposable flags. It protects credits by skipping malformed or duplicate addresses and stopping runs on invalid keys or exhausted balances.

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

An MCP server that checks SPF, DKIM, DMARC, and MX records for a domain, returning a health verdict and specific DNS fixes to improve email deliverability.

Enables MCP clients to validate email addresses locally before sending or saving them, detecting typos, disposable domains, dead domains, bad syntax, role addresses, duplicates, and provider information.

Self-hosted, multi-account Gmail MCP server for Claude and Codex over Streamable HTTP, with explicit account aliases, owner-only OAuth, and encrypted credential storage. Supports searching and reading email, creating drafts, and optional sending and label changes.

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.
