"Information about queue-based systems or concepts" matching MCP servers:

Provides a local MCP server for inspecting offline .eml files without network access, exposing a single tool to generate redacted JSON summaries with nested-message and delivery-status details.

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

Connects AI assistants to Masaryk University's information system in read-only mode, letting students ask about their timetable, deadlines, emails, grades, and study materials in natural language.

Official GoodSender MCP server: publish blog posts, send newsletters and consent-based or transactional email from Claude, Claude Code, Codex and ChatGPT. Hosted (OAuth) or local.

A plugin-based MCP server that securely exposes custom tools to AI agents, keeping sensitive information hidden while enabling operations like email whitelisting through pluggable plugins.

Enables AI assistants to chat about Nehan Chandira's CV and send email notifications.

Lets AI agents send and queue Gmail messages through MCP tools, enforcing Gmail sending limits and encrypting tokens at rest.

MCP server for Mimecast Email Security — message tracking, threat intelligence, and email queue management. Enables AI assistants to investigate and manage email security events.

Enables AI assistants to flag email addresses and domains as disposable, role-based, free-mail, or look-alike via list-based lookups with no MX checks. Exposes check_email, check_domain, and get_meta tools over remote Streamable HTTP.

Aggregates MCP tools for remote control, email, system monitoring, and web search, enabling AI to interact with external systems.

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.

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.

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.

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.

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.

Enables AI agents to list, read and download the files attached to Gmail messages, extracting text from PDFs, Word, Excel, PowerPoint and plain-text files straight into context or saving them to disk. It runs locally with read-only Gmail access, so attachments can be summarised, checked or analysed without leaving the chat.

Free MCP and skills for remote and overseas job search across Himalayas, Jobicy, Arbeitnow and company ATS boards, with source links and eligibility checks. Optional local drafts, authorized email sending and reply tracking. Hosted MCP: https://mcp.worldrole.work/mcp — free anonymous access to 20 distinct jobs per network per UTC day, or 50 per free account; other request limits apply.

Hosted email for AI agents. Connect Gmail, Outlook / Microsoft 365 or any IMAP mailbox to Claude, ChatGPT, Cursor and other MCP clients, then read, search, send, organize, draft, schedule and auto-triage mail. Email is fetched live and never stored. Free for 1 inbox.

Enables connecting and searching multiple Gmail or Google Workspace accounts via friendly aliases, with read-only access and source mailbox attribution for each result.
