"User Interface Design or Concepts" matching MCP servers:

Multi-user Gmail MCP server that enables sending/receiving emails, managing accounts, and searching mail via SMTP/IMAP with per-user isolation and encrypted app passwords.

Enables AI agents to programmatically manage email outreach campaigns, leads, domains, senders, and webhook events, as well as send emails, through the Model Context Protocol over HTTP.

An MCP server that provides email verification, returning valid, invalid, or risky status with detailed checks and metadata. It enables verifying email addresses via a simple tool interface.

Enables sending emails via Amazon SES, SMS/MMS/RCS messages through AWS End User Messaging, and sharing files via CloudFront-signed download links, all from AI assistants like Claude Code or Claude Desktop.

Enables an AI agent to send or draft email as the signed-in user through Microsoft Graph, including multiple recipients, HTML or plain-text bodies, and file attachments. Uses delegated least-privilege PKCE authentication so messages can be staged as drafts for approval or sent directly.

Enables AI agents to autonomously receive, search, read, reply to, and forward email through a self-hosted Cloudflare service accessible via MCP or CLI, with no web interface.

Provides AI agents with tools to manage mailboxes, send email through user-configured SMTP accounts, and draft or triage messages using an Anthropic key.

Enables searching, reading full conversations, and sending email across multiple IMAP/SMTP mailboxes from any MCP client, with multi-user support and per-user API tokens.

Self-hosted MCP server that filters sensitive data from email and calendar before it reaches AI assistants, masking or withholding confidential content based on user policy.

A private, single-user MCP server that unifies Gmail, Microsoft 365/Outlook, and IMAP mailboxes for LLMs to search and read emails live, without storing or caching mailbox contents.

MCP interface for smbCloud

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.

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 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 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.

Enables AI agents to verify email addresses and receive a 'send', 'hold', or 'kill' verdict with the reason, while also managing signup and credits programmatically.

This MCP server provides comprehensive Google Workspace integration (Gmail, Drive, etc.) with multi-user OAuth. Unique features include RAG-powered natural language to Chat card rendering, runtime Jinja2 macro creation, and dynamic tool management.

Diagnoses a domain's email authentication — SPF, DMARC, DKIM, MX, blacklists and domain or SSL expiry - and returns copy-paste fix records generated by a validating engine, never a language model. The MCP server is hosted remotely; this repository carries the plugin manifest, connector config and bundled skill.

Gives an AI assistant read- and draft-only access to a single personal Microsoft mailbox, letting it search, list and read mail, browse folders, save attachments to a jailed directory, and create new or reply drafts. It requests no send scope, so mail can never be sent, deleted, moved or marked, and calendar, contacts and files are untouched.
