"User interface design or related topics" 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 check an email address for syntax validity, MX records, disposable/role/free-provider flags, and a deliverability score/verdict, with per-call USDC payment on Base.

Enables users to audit a domain's email-authentication DNS configuration—covering SPF, DKIM, DMARC, MX, BIMI, MTA-STS, and TLS-RPT—and receive issues, recommendations, a 0–100 score, and A–F grade.

Exposes named core, finance, supplier, intake, orders and reports tools over HTTP so Claude Code subagents can run a self-hosted finance back office: reading and coding supplier invoices, posting bills to the owner's QuickBooks, matching the bank, keeping the cashflow outlook, reconciling supplier statements and drafting reports and emails. Every write passes a posting gate and no payment, approval or customer invoice can be issued by an agent.

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.

Enables an AI agent to search, read, and create Gmail drafts for user review, with no capability to send, delete, archive, or relabel mail.

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 MCP clients such as Claude to read, send, reply to, forward, and organize mail in classic Outlook on Windows through the local COM interface, without admin consent, app registration, or tokens.

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.

Enables AI agents to perform user-authorized Gmail sending and non-destructive Google Docs text appending via a client-agnostic Model Context Protocol interface. It emphasizes least-privilege scopes, confirmation for outbound email, and zero-PII logging.

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

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

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.

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 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.

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.

Let AI agents search and read your mail: on-premises Microsoft Exchange (EWS, no cloud API or admin setup) and any IMAP mailbox, tested on Mail.ru and Gmail. Text inside PDF, Office and ZIP attachments is searchable in Russian and English. Runs from a local copy, and read-only is enforced at the protocol level.

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.

Enables checking lead rows, CSV files, or Apify datasets for duplicates, email syntax and risk signals, domain issues, missing fields, and stale dates, returning a per-row import, review, or reject verdict so only clean records reach a CRM or sequencer.

Email inboxes for AI agents: create a throwaway inbox, then block until the OTP or magic link arrives and get it back as a field. 7 tools, stdio, Python.

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.

Enables AI assistants to search and read institutional IMAP mailboxes, download attachments, mark messages read or unread, move them between folders, and save drafts, all safely by UID. Runs locally over stdio or as a remote HTTP/SSE endpoint secured by a bearer token for clients like ChatGPT and n8n.

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.

Baryon connects MCP-compatible AI assistants to Proton Mail through a local bridge, enabling email search, reading, attachment handling, and draft creation while enforcing deliberate permission limits. It runs locally and cannot send, delete, or modify mail.

Enables agents to validate and normalize phone numbers, email addresses, and postal addresses with production-grade, country-specific rules, including formatting, typo detection, and checks for disposable domains or fictional numbers.

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.
