"SQL-Based Technologies or Concepts" matching MCP servers:

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.

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.

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.

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 and 150 email actions a month.

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

A Gmail MCP server that enables Claude to send, search, and read emails using either Gmail API or SMTP/IMAP backend.

Enables searching, reading, exporting and downloading Google Docs, Drive files and Gmail messages through Google's REST APIs, authenticating with access tokens minted by the locally installed Cloud SDK CLI so no separate OAuth client is needed. Optional write tools let the model create Docs, replace or append content, and draft Gmail messages.
