"User Interface Design or Information" 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 AI assistants to validate individual or batch email addresses for deliverability, and to check account plan information, through MCP tools.

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.

Lets MCP clients read local Thunderbird mail, search messages and contacts, request bounded mailbox changes such as moves or tags, and prepare outgoing messages in Thunderbird’s native composer for user review and manual sending.

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 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.
