"User interfaces (UI) or UI design resources" matching MCP servers:

A FastAPI-based MCP server that integrates with Google Docs and Gmail, requiring terminal approval before executing actions.

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.

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 an LLM agent to work a FreeScout support inbox without an API key, authenticating through the normal web UI with a pasted browser session cookie or FreeScout username and password. It lets agents read and search conversations, pull ticket and satisfaction reports, add internal notes, save reply drafts, manage tags, close tickets, and optionally forward to an operator allow-list — all under the agent's own mailbox permissions, and never emailing customers.

Enables reading and sending emails via IMAP and SMTP through the MCP protocol. Supports multiple email accounts and configuration via UI or environment variables.

Comprehensive MCP server for Pipedrive CRM with 118 tools and 27 UI apps, enabling full CRM operations via natural language.

Enables appending content to Google Docs and creating Gmail drafts with human-in-the-loop approval, integrating structured AI tool interfaces via MCP-style endpoints.

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.

Enables AI assistants to send, read, search, and manage emails directly through structured IMAP/SMTP tools, without UI automation.

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.

Enables interaction with SQLite databases, filesystem, AWS IAM, and Gmail through a master MCP server with a Streamlit UI optimized for Claude.

Enables users to access and manage their Gmail and Google Drive data via a Streamlit UI or Claude Desktop, supporting email counts, searches, file listings, and storage queries using OAuth authentication.

Enables MCP-compatible AI clients to access 21Vianet Microsoft 365 mail, calendar, OneDrive, SharePoint, Teams, contacts, and other Microsoft Graph China resources as the signed-in user, with delegated permissions, operation confirmation, and audit controls.

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.
