"An agent for conducting research" matching MCP servers:

An MCP-powered AI agent that audits your Gmail for recurring subscriptions, detects silent price increases, and flags unused services.

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.

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.

Enables AI assistants to manage multiple Outlook/Microsoft 365 mailboxes simultaneously through MCP tools, with local OAuth token storage.

Agent-native cold-email infrastructure providing ~12 high-level tools for domain setup, mailbox provisioning, campaign launch, inbox management, and metrics, all operated via MCP or CLI.

MCP server that gives an AI agent a throwaway test identity — a real disposable email address and a real UK phone number — so it can sign up for something it's testing and read back the verification email/SMS itself, without a human in the loop.

Enables AI agents to create temporary email addresses, receive confirmation emails, and extract verification links, automating sign-up and email verification workflows without manual intervention.

MCP server that encapsulates Apple Mail on macOS via AppleScript, enabling invoice PDF search, attachment saving, and message flagging through natural language.

Create disposable email inboxes, extract OTP codes in 15 languages, and receive webhooks — all from your AI agent. One call: create inbox → wait for email → get the verification code. Supports 7 domains, email forwarding, and HMAC-signed webhooks with OTP included in payload. Free tier available.

Enables an AI agent to search, read, and create Gmail drafts for user review, with no capability to send, delete, archive, or relabel mail.

MCP server for SentVia that provides email infrastructure for AI agents, enabling them to create inboxes, send, reply, forward, search messages, manage drafts, domains, webhooks, and allow/block rules through 21 tools.

Enables local AI agents to search and read iCloud Mail, draft and send reviewed replies, and manage calendar events via a local MCP connection.

Enables AI assistants to connect to Gmail accounts, check connection status, and send emails through a secure OAuth 2.0 interface.

Outbound sales agent for Claude Code. MCP server handles prospect list building, dedup, quotas, and structured rejection feedback, while the plugin runs per-prospect research, email writing, Gmail sending, and reply tracking. Open source, self-hostable.

Enables an AI agent to discover and call bounded Microsoft 365 tools for reading calendar, mail, Teams channels, SharePoint, and Power Platform metadata through MCP, with synthetic fixtures by default and optional Microsoft Entra/Graph tenant integration.

Enables AI agents to securely interact with Gmail and QQ Mail, including IMAP search/read/organization, attachments, and preview-confirmed sending.

An MCP server for managing Proton Mail, Pass, Drive, and Calendar through local IMAP/SMTP, pass-cli, and Proton Drive CLI, enabling AI agents to operate the mailbox, manage passwords, sync files, and classify emails.

Provides email discovery, verification, enrichment, and company research through a remote MCP server.

Enables users to arrange a meeting with the OpenWork team in San Francisco from inside an MCP-capable agent, using an interactive 3D café card, email confirmation, and automatic time, place, and calendar invite details.

A production-style MCP server exposing six business tools (web search, database, CRM, email, calendar, analytics) to AI clients via a secure, authenticated interface, with mock mode and a reference agent client.

Enables software agents to read and manage their own mailboxes, inspect inbound messages, and request outbound email that remains pending until an owner approves it. Exposes these agent mail operations as remote MCP tools alongside a REST API.

Multi-agent sales email generation server that creates, evaluates, and sends personalized sales emails via SendGrid, using AI to craft diverse email styles and select the best one.

Enables AI apps on the local computer to search and read Thunderbird mail, organize messages, manage contacts, and prepare drafts, with optional controlled sending. Access is limited to user-selected accounts and tool groups, with local-only communication and a pause control.

Enables an AI to send and receive letters through its own mailbox while contacts are shown only by remark names, avoiding raw-address mix-ups. It provides tools to list recent unread messages, read full letters, and send to known contacts, with optional pre-send pause and recipient-name checks.

An open-source MCP server that provides AI agents with secure access to read, search, and manage emails via Microsoft 365 and Gmail. It features security-first defaults like recipient allowlists and markdown content conversion to facilitate safe agent interaction with mailboxes.

MCP server for Yahoo Mail over IMAP+SMTP that enables AI assistants to manage emails fully—listing, reading, searching, threading, flagging, moving, archiving, handling attachments, and sending/reply/forward/draft—using an app-specific password.

Gives an agent (like Claude) complete control over a Gmail or Google Workspace account via IMAP/SMTP using an app password, without needing OAuth.

Enables ChatGPT and Codex to interact with Zoho Mail through Zoho's official MCP service, with safe workflows and capability boundaries.

Enables AI agents to read, send, and reply to GPG-encrypted email over IMAP/SMTP, manage a contact book with key provenance, and archive and search everything read. Key material and message bodies are kept out of the model's context window, with encryption enforced by default.

Enables Claude Desktop on Windows to search and read Yahoo Mail messages in read-only mode, without sending, deleting, or otherwise modifying them.
