"Understanding Feedback Enhanced Concepts or Technologies" matching MCP servers:

Comprehensive MCP server for Google Workspace with complete Gmail API coverage (27 tools) and Google Calendar integration with automatic Google Meet links, enabling advanced email management, label operations, archive workflows, and calendar event creation/updates through natural language.

Enables deterministic email triage by classifying messages into P0–P3 or REVIEW and emitting the pif.event.v1 contract. Provides tools for rendering Feishu messages, recording feedback, and retrieving policies, while leaving mailbox actions to Hermes.

Enables AI-powered Gmail triage: fetches unread emails, classifies them, drafts replies for important ones, and sends only after user approval via conversational review. Exposes tools for checking unread emails and submitting review feedback from Claude Desktop or any MCP client.

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 pushing enriched leads into Instantly or Smartlead campaigns with ICP score gating, deduplication, and dry-run previews via an Apify actor.

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.

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.

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.

An MCP server that exposes a local notmuch email database to an LLM client such as Claude. It is read-first: searching, reading, and understanding mail is always available; writing anything (drafts, tags, exported files) requires an explicit opt-in flag and is confined to clearly bounded locations.

An email MCP server that lets Claude or any MCP client search, read and draft mail via IMAP, treating every message as untrusted input. It prioritizes safety with plain-text-only bodies, disabled sending until an allowlist is set, and no bcc support.

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.

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.

MCP server that gives an agent its own email inbox: it opens the inbox, waits for the one-time code a signup sends, and reads or sends mail. Addresses are permanent, so a test suite does not need a new one per run; only the messages expire, on a retention window you set.

Your real mailbox and calendar for your AI agent — Microsoft 365 via Graph or any IMAP — as 24 tools: read, search, attachments as text, sender history, drafting from identity and knowledge files, free-slot computation. Send, reply, delete and calendar writes need out-of-band human approval: the agent cannot approve its own actions.

MCP server that gives an AI assistant simultaneous access to multiple Gmail accounts with per-account read-only, draft, or send tiers, two-phase write confirmation, and safeguards for handling untrusted email content.

Enables email address verification through a single MCP tool, returning whether an address is valid, invalid, or risky.

MCP server that enables AI agents to search and read locally-archived emails via the Bichon email archiver API, without exposing Gmail or IMAP credentials.

MCP server for Claude to access on-premises Outlook/Exchange mailboxes via EWS with NTLM authentication, providing tools for email, calendar, and contact management without relying on Microsoft 365 or Graph API.

Give Claude (or any MCP client) a real email inbox and SMS. Your AI agent can read and send email, manage inboxes, track delivery, and handle SMS.
