Overview

Description from the maker (original English)

Hosted per-user MCP server for your personal WhatsApp: reminders, follow-ups, summaries, replies.

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Chat & email
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

  • Basic checks: 1 of 1 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • You fill in yourself: Authorization

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http whatsapp 'https://{user}-mcp.relaymcp.app/mcp' --header 'Authorization: your-value'

Fill in the empty values before running it.

The address contains {…} parts that only you know (such as your account), so copy it and fill them in.

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "whatsapp": {
      "url": "https://{user}-mcp.relaymcp.app/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is RelayMCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.0) reached the registry 25 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

In the same category: Vexa, emailmd, MCP WhatsApp Cloud

RelayMCP: a WhatsApp MCP server for your AI assistant

RelayMCP is a hosted, per-user Model Context Protocol (MCP) server that connects ChatGPT, Claude, Cursor and other MCP clients to your own personal WhatsApp, with privacy and anti-spam safeguards.

Private pilot, invite only. Join the waitlist at https://relaymcp.app.

Setup guides: https://relaymcp.app/guides/

This repository holds documentation and directory metadata only. It contains no source code.

RelayMCP is an independent product. It is not affiliated with, endorsed by, or sponsored by WhatsApp or Meta.

What you can ask your AI to do

  • Reminders: "Remind me tomorrow at 10 to call Rahul back."
  • Follow-ups: "If the supplier hasn't confirmed by Friday, draft a nudge."
  • Find what someone said: "What time did Priya say the meeting was?"
  • Summarise chats: decisions, questions for you, and anything waiting on your reply.
  • Draft and send replies to your contacts, one person at a time.
  • Voice notes and media: voice notes are transcribed (Hindi and English), and your AI can read images and documents people send you.

How it works

  1. Link WhatsApp. Scan a QR code under *Linked devices* on your phone. RelayMCP joins as a companion device, and your old chat history isn't imported.
  2. Connect your AI tool. Add your personal RelayMCP URL as a remote MCP server.
  3. Set your privacy, then ask. Block the chats you want kept private, choose how long messages are kept, and start asking.

Connection details

Endpointhttps:// -mcp.relaymcp.app/mcp (one per user, issued when you join the pilot)
TransportStreamable HTTP
AuthOAuth 2.1 with Dynamic Client Registration, or a bearer API key (Authorization: Bearer rmcp_live_...)

Example client config (API key):

{

"mcpServers": { "relaymcp": { "url": "https:// -mcp.relaymcp.app/mcp", "headers": { "Authorization": "Bearer rmcp_live_..." } } } }

Clients that support OAuth (ChatGPT, Claude) only need the URL. Step-by-step guides are at https://relaymcp.app/guides/.

Tools (34)

Contacts and chats: search_contacts, get_contact, list_chats, get_chat, get_direct_chat_by_contact, get_contact_chats, get_last_interaction Messages: list_messages, get_message_context, mark_messages_read, list_waiting_on_me Sending: send_message, send_reaction, send_file, send_audio_message, get_send_queue, cancel_queued_message Media: download_media, view_media, get_media, transcribe_audio Groups (read only): list_groups, list_group_members Reminders and follow-ups: create_reminder, schedule_followup, list_followups, update_followup, cancel_followup Privacy and account: block_chat, list_blocked_chats, request_unblock_chat, get_unblock_request_status, get_privacy_status, get_account_status

Privacy safeguards

  • Block any chat or group. Its messages are dropped the moment they arrive: never stored, never shown to the AI, media never downloaded. Blocking also wipes anything already stored for that chat.
  • Only you can unblock. Unblocking needs a code shown only on your own RelayMCP dashboard. Your AI never sees it.
  • Short memory. Messages are deleted automatically after 72 hours (adjustable). Old chat history isn't imported when you link.
  • Encrypted at rest. Message text is encrypted at rest, in storage on AWS in Mumbai, India. Logs never contain message text.
  • Delete anytime. Unlink your device and all your data is wiped.
  • No selling. Messages are used only to run the features you use, never sold or used for ads. Handled in line with India's DPDP Act, 2023.

Anti-spam safeguards

RelayMCP is a reminder and follow-up tool, not a broadcast tool.

  • Messages go out after a random 30 to 120 second delay, never in bursts.
  • Each message goes to exactly one person. No groups, lists or broadcasts.
  • Only people in your contacts or chats you already have.
  • Quiet hours: no sends between 9 PM and 9 AM in the recipient's local time.
  • About 30 unique recipients a day, and the same text can go to at most 3 people.
  • Accounts used for spam or bulk messaging get paused or banned.

RelayMCP uses WhatsApp's linked-devices feature. Use it for your own conversations and in line with WhatsApp's terms.
