Servers in this category

244 of 244
ni-c/carddav-mcp Contacts, groups and photos over CardDAV, on any server that speaks the standard — Radicale, Baikal, Nextcloud, SOGo, Fastmail, iCloud. 17 tools. Writes are read-modify-write over the parsed card guarded by ETags, so an X- property some phone wrote in 2014 survives an edit; both group conventions are read and the one written follows what the book already uses; an address book allowlist is enforced where ids are decoded rather than per tool. Card text is treated as untrusted input, because a card claiming somebody's bank details changed does not need the model to run a tool, only to be believed. npx -y @ni-c/carddav-mcp
ni-c/smtp-mcp Sends, replies to and forwards mail over plain SMTP, so it works with the mail account you already have. Sending is off until you name the recipients it may write to: every address in To, Cc and Bcc is checked against that allowlist before a connection is opened, and each message is then approved by a person through an MCP elicitation, with recipients and subject on their own labelled lines. There is no from parameter, so a model cannot write in a colleague's name. The counterpart to imap-mcp, in its own process with its own credentials. npx -y @ni-c/smtp-mcp
ni-c/caldav-mcp Events, tasks and journal entries over CalDAV, on any server that speaks the standard — Radicale, Baikal, Nextcloud, SOGo, Fastmail, iCloud. 22 tools. Recurring events are expanded client-side rather than trusted to the server, a calendar allowlist is enforced where ids are decoded, writes are read-modify-write guarded by ETags, and deleting or changing a whole series asks a person first. Calendar text is treated as untrusted input, because anyone who can send an invitation can put text in your calendar. npx -y @ni-c/caldav-mcp
farukkolip/instapdown-mcp Instagram creator toolkit MCP with 16 tools: Reels / video / Story / carousel / photo / profile-pic downloaders, Reels-to-MP3 audio extractor, engagement health check + weighted engagement-rate calculator, live hashtag search + 25 curated niches + creator hashtag audit, 900 Reels hook templates by niche and country, 22 Unicode font styles, best-time-to-post for 17 markets (Buffer 2026 verified data), and a 750-date 2026 content calendar with per-market playbooks. Wraps instapdown.com public API — no auth required.
krystiangw/meet-live-assist-extension Puts the agent you already run inside a live Google Meet or Zoom call. A Chrome extension reads the on-screen captions, a local server hands them over MCP, and the agent answers in a side panel while people are still talking, posts to the meeting chat, and reads screenshots of a shared screen. Transcripts and screenshots are files on your own disk; there is no hosted service and no account. Needs an MCP client attached - Claude Code is the tested one. Install with npx meet-live-assist-server.
ma2no4413/outlook-mcp Restructure a large Outlook / Hotmail mailbox. movefolder relocates a whole folder subtree in one API call — thousands of messages change place without being moved, their IDs stay valid, and inbox rules pointing at that folder keep working. Also bulk move and bulk mark-read with dry-run previews, and server-side inbox rules as first-class tools. Replies are written to Drafts; there is no send tool and Mail.Send is never requested. Deletes only ever reach Deleted Items.
dockndevai/mcp-outlook Safe-by-default Microsoft Outlook mail server (Microsoft Graph). Read, search, draft, send, reply, forward and organize email. Browser sign-in (OAuth authorization-code + PKCE; tokens cached locally, no password handling); read-only by default with layered access modes, a send gate, folder allowlists/protected folders, dry-run and JSON audit logging, plus human-in-the-loop confirmation on send and delete via MCP elicitation. npx -y @dockndevai/mcp-outlook.
farukkolip/xtapdown-mcp X (Twitter) creator toolkit MCP with 14 tools: tweet download (video/GIF/image/full archive), curated hashtags by niche, best posting times by country, viral hook formulas, engagement & ads-revenue calculators, thread splitter, character counter, advanced-search URL builder, fancy Unicode bio generator, viral patterns lookup, and the full 2026 search-operator cheatsheet. Uses X's public syndication endpoint — no auth, no rate limits on curated data.
radmail-ai/radmail-mcp Email operating system for agents: a search tool to find the one message by sender/subject/content (no filesystem grep), two-axis triage (importance × urgency), an explainable "Right Now" lane, commitment follow-through, and reviewable drafts. A machine-verifiable hard-stop keeps money/banking-change/first-contact human-only (BEC defense). Zero-auth HTTP sandbox at radmail.ai/api/mcp/sandbox — no account, no key.
ictinnovations/ictbroadcast-mcp MCP server for ICTBroadcast, a voice, SMS and fax broadcasting and call centre platform. Lists campaigns and reads their live status, totals and per-call results including answer, machine detection and do-not-call outcomes. Starting and stopping a campaign places live calls, so those two tools are only registered when ICTBROADCASTMCPALLOWWRITE=true. Zero-install via npx -y ictbroadcast-mcp.
adecubed/gigamail Your real mailbox and calendar for your agent (Microsoft 365 via Graph, or any IMAP): 24 tools for reading, search, attachment text, sender history, drafting from identity and knowledge files, and free-slot computation — with out-of-band human approval on every send, reply, delete and calendar write, so the agent cannot approve its own actions. pip install "gigamail[all]".
hgn/mcp-server-notmuch notmuch MCP server. Wraps the notmuch CLI to give your LLM access to a local Maildir: full-text search, tag filtering, thread view, attachment reading (PDF, office docs, .ics), related-thread lookup, and unanswered-mail tracking. Optionally write plain-text drafts into a local maildir (--allow-drafts) or manage tags (--allow-tags). No SMTP, no sendmail.
Albretsen/MCPEmails Hosted email MCP server for Gmail, Fastmail, iCloud, Yahoo, Zoho, Yandex and any IMAP/SMTP mailbox. 11 action-based tools to read, search, send, organize, draft, schedule and auto-triage mail. Streamable HTTP at https://mcpemails.com/api/mcp, OAuth 2.0 with PKCE or scoped API keys, mail fetched live and never stored. Docs at https://mcpemails.com/docs.
drsound/markdown-to-whatsapp Convert Markdown into WhatsApp's formatting, so agent output renders as bold, lists and quotes instead of showing raw asterisks. Tables become monospace boxes sized to the reader's bubble width, degrading through padding removal, compact borders and word wrapping before falling back to a list. No API key, runs locally with npx markdown-to-whatsapp mcp.
parasxos/apple-mail-mcp Full-featured MCP server for Apple Mail. Indexed search over 300k+ message mailboxes in milliseconds, full-text body search with Exchange backfill, verified multi-identity sending (SMTP/Keychain, SSH bastion, pipe), server-side scheduled sends with cancel, reviewed plan-then-apply triage, and a local audit ledger. 21 tools, frozen v1 wire contract.
madbonez/caldav-mcp Universal MCP server for CalDAV protocol integration. Works with any CalDAV-compatible calendar server including Yandex Calendar, Google Calendar (via CalDAV), Nextcloud, ownCloud, Apple iCloud, and others.

Runs locally over stdio or as a hosted endpoint where each user brings their own API key. Install with npx -y @markmnl/fmsg-mcp.

Deploy via Docker, npm, or from source.
lettio-eu/mcp Private, EU-hosted email for AI agents over the open JMAP standard. Read, search, reply in-thread, organize and send from your own mailbox. Hosted remote server with OAuth at https://mcp.lettio.eu/mcp, or run locally via npx -y @lettio/mcp. Sending is pinned to the signed-in mailbox, so an agent can never send from another address.
Infobip/mcp Official Infobip MCP server for integrating Infobip global cloud communication platform. It equips AI agents with communication superpowers, allowing them to send and receive SMS and RCS messages, interact with WhatsApp and Viber, automate communication workflows, and manage customer data, all in a production-ready environment.
carterlasalle/macmessagesmcp An MCP server that securely interfaces with your iMessage database via the Model Context Protocol (MCP), allowing LLMs to query and analyze iMessage conversations. It includes robust phone number validation, attachment processing, contact management, group chat handling, and full support for sending and receiving messages.
ictinnovations/pbx-mcp MCP server for Asterisk and FreeSWITCH. Reads live PBX state over AMI and ESL: registered extensions, active channels, trunk and SIP peer status, dialplan lookups and call history. Read-only by default, and write tools are never registered with the model at all unless PBXMCPALLOWWRITE=true. Zero-install via npx -y pbx-mcp.
andrewchmr/mxprobe Email verification for AI agents: one call returns send, hold or kill for an address, with the reason. The free DNS tier runs locally with no key; the hosted SMTP probe costs 9 USD per 10,000 checks. Signup and credits are API calls too, so an outreach agent provisions itself (no dashboard, no CAPTCHA). npx -y mxprobe mcp
gopalrajsuresh/covalent-bond Pair two AI coding agents on different machines over an end-to-end-encrypted channel: files and messages travel through a relay that only ever sees ciphertext - it can never read your data - authenticated by a short code shared out-of-band, with human consent before any file is written. Install with npx covalent-bond.
ictinnovations/ictpbx-mcp MCP server for ICTPBX, a multi-tenant IP PBX built on ICTCore and FreeSWITCH. Reports PBX statistics and lists extensions, DIDs, providers and tenants over the ICTCore REST API. Entirely read-only: there are no write tools to gate, so it cannot change PBX configuration at all. Zero-install via npx -y ictpbx-mcp.
ni-c/ntfy-mcp Send push notifications through ntfy, read back what was sent, and revise a notification in place while a job runs, so subscribers watch one message change instead of collecting five. Thirteen tools including user and topic-access administration; the tool list narrows to a curated six. npx -y @ni-c/ntfy-mcp
grzgrzgrz3/pingwa-client WhatsApp notifications for AI agents with zero setup — no Meta account, no templates, no dashboard: text "join", get an API key, send in 60 seconds (uvx pingwa mcp or remote at pingwa.dev/mcp).

desek/outlook-local-mcp Local-first Microsoft Outlook MCP server (calendar + mail via Microsoft Graph).
