Provides AI assistants with access to Google Workspace APIs including Sheets, Calendar, Gmail, Tasks, Drive, and Docs. Enables full CRUD operations and management of Google services through natural language.

Enables an AI agent to act as first-line customer support on top of Microsoft Dynamics 365 / Dataverse, reading incoming synced emails, looking up contacts and published knowledge articles, and drafting HTML-safe replies or escalating to a human as a Case. Runs draft-only by default with safeguards against prompt injection, duplicate replies, and unsafe recipients.

An MCP server that enables AI agents to manage Smartlead campaigns, including creating campaigns, updating schedules, managing email sequences, and adding leads, all over SSE.

Provides email sending and receiving via SMTP/IMAP/POP3, supporting major email providers and dynamic authentication for AI assistant integration.

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

An MCP server for Gmail that allows AI assistants to read, search, compose drafts, send emails, and manage labels with attachment support.

A Model Context Protocol server that provides email access via IMAP and SMTP, enabling AI agents to read, search, send, and manage emails. It features specialized tools for folder management, message retrieval, and replying to threads through a standardized HTTP/SSE interface.

Enables AI assistants to read, search, send, reply, forward, schedule, and analyze email across multiple IMAP/SMTP accounts, with drafts, templates, provider-aware labels, bulk operations, attachment handling, calendar extraction, and real-time IMAP IDLE watching. Connections are secured with TLS/STARTTLS, OAuth2 support, and rate limiting, and it can run over stdio locally or Streamable HTTP for networked access.

A mail service that connects private domain email to MCP clients, enabling sending (with auto signature), receiving, and reading emails through natural language via stdio or SSE transport.

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

AI-powered email assistant that enables sending, parsing, and managing emails using natural language. Provides 4 tools (smart_email, parse_email_intent, send_email, email_chat) with SSE/stdio transport support.

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.

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.

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

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.

A read-only MCP server that lets Claude Desktop interact with Apple Mail on macOS via AppleScript. It enables listing mailboxes, searching emails, and reading email content without making network calls.

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

One MCP server holding a live session with every client's account at once, so one agent can read across a dozen businesses and write inside only the one you name. It forwards each provider's own MCP tools (Cloudflare, Vercel, Resend, Supabase, Linear, Notion, Sentry, Netlify and more) with that client's credentials, and adds deterministic DNS and email checks that never call a model.

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.
