"Information on the Theory of Evolution" matching MCP servers:

MCP server for GNOME Evolution that enables calendar and email operations such as listing calendars/events, sending emails, and searching messages through the Evolution Data Server.

Enables coding agents to research and score leads against industry ICP templates, draft cold emails, and gate every draft through CAN-SPAM and deliverability checks before a human approves it. Nothing is sent by default, and each step is recorded in an append-only audit log showing why a lead was contacted.

Enables MCP clients to exchange an MCP-audience token for a Microsoft Graph token and call Graph as the signed-in user, with tools for identity verification and recent mail access.

Connects Claude to on-premises Exchange via EWS and Active Directory, enabling natural-language meeting-room booking, free/busy checks, calendar management, email handling, and org-chart-aware scheduling with OIDC-authenticated impersonation.

Enables AI assistants to manage Microsoft Outlook Desktop (Classic) calendar and email through local COM automation, without Microsoft Graph or Entra registration.

An enterprise-grade MCP server that provides production-ready IMAP email integration with advanced reliability features, comprehensive monitoring, and secure account management.

An MCP server that integrates with the Beehiiv newsletter platform to retrieve subscriber information with filtering, pagination, and optional expanded data.

An MCP server that enables AI assistants to read-only search and retrieve GNOME mail, contacts, and calendar data using IMAP and Evolution Data Server, with no password storage.

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.

Detects whether a company runs cold email outbound and identifies the email sending infrastructure, including sending domains, platforms, and authentication status.

Enables read-only access to a single Gmail mailbox, listing emails within a date range and retrieving full headers and body text of individual emails, with deep-link jump URLs for each result.

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 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.

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.

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.

A read-only MCP server that lets Claude Desktop interact with Apple Mail on macOS via AppleScript. It enables listing mailboxes, searching emails, and reading email content without making network calls.

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 MCP clients to read and search Proton Mail and create draft-only emails with attachments through the local Proton Mail Bridge, while requiring out-of-band human approval before a draft can be committed.

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 assistants to verify email deliverability and find business emails via the Verifox API, supporting single and bulk operations.

Send email through your own Amazon SES account, and check domain verification, the suppression list and sandbox status. Works with any SES account; Wraps adds send history and delivery events.

Enables Gmail label management with tools to list, create, delete labels, and modify labels on messages and threads, handling OAuth2 authentication automatically.

Enables AI assistants to interact with Fastmail services, providing tools for comprehensive email management, contact searching, and calendar event coordination via the JMAP API. It supports advanced features like threaded conversations, attachment handling, and bulk mailbox operations through natural language.

Enables reading replies, bounces, unsubscribes, meetings, interest changes, and LinkedIn replies from the user's own Instantly, Smartlead, HeyReach, and lemlist accounts, returning one flat row per event over a chosen time window. It is read-only and runs the polling work on Apify.

This MCP server bridges AI agents with Apple Mail on macOS, enabling email operations like reading, sending, drafting, searching, and scheduling through natural language, with added features like stable draft IDs and confirmation-gated sending.

One MCP server holding a live session with every client's account at once, so one agent can read across a dozen businesses and write inside only the one you name. It forwards each provider's own MCP tools (Cloudflare, Vercel, Resend, Supabase, Linear, Notion, Sentry, Netlify and more) with that client's credentials, and adds deterministic DNS and email checks that never call a model.

Giggal.ai is an email verification tool that runs a deep mailbox existence check on every address and verifies catch-all/accept-all and even SEG protected emails. Your bounce rate stays under 5%, and the 30% of every B2B list that other tools flag as "Risky" becomes deliverable again.

Local-first Microsoft Outlook MCP server: a single Go binary that manages calendar events and mail through the Microsoft Graph API over stdio, with tokens stored in the OS keychain and no Entra ID app registration required. Exposes four aggregate tools (calendar, mail, account, system) dispatched by an operation verb, with multi-account support and read-only and mail-gating modes.

Enables an AI agent to send files end-to-end encrypted, encrypting on the user's computer and keeping the download link key, password, and login away from the model.

Lets Claude read email and read/write calendar events for personal Microsoft accounts (Hotmail/Outlook/Live) via Microsoft Graph API, filling the gap where the official connector only supports work/school accounts.
