Overview

AI-generated overview

Hosted per-user MCP server that connects an AI assistant to your own WhatsApp for reminders, follow-ups, chat summaries and replies.

What you can do
  • Search and read contacts, chats and messages, including message context and what is waiting on your reply
  • Send messages, reactions, files and audio notes, with a queue you can inspect or cancel
  • Download and view media, and transcribe voice notes in Hindi and English
  • List groups and group members (read only)
  • Create, list, update and cancel reminders and follow-ups
  • Manage privacy and account: block chats, request unblock, check privacy and account status
When to use it
Useful if you want an assistant to work inside your personal WhatsApp: recalling what someone said, summarising chats, drafting and sending one-to-one replies, and setting reminders or follow-ups on conversations.
Requirements
A remote MCP endpoint issued per user when you join the invite-only pilot, plus a linked WhatsApp account via QR code under Linked devices. Authentication is OAuth 2.1 with dynamic client registration, or a bearer API key sent in the Authorization header.
Before you install
The assistant can read your chats and send messages, files and audio as you; sends are rate-limited and delayed but still go to real contacts. Message text is stored encrypted on AWS in Mumbai, India, kept about 72 hours by default, and voice notes are transcribed. Blocking a chat wipes its stored data, and unblocking needs a code from your dashboard. Pilot is free now; paid plans are planned.

Installation

In SourceWeft

  1. Open RelayMCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

README

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://<user>-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):

json
{  "mcpServers": {    "relaymcp": {      "url": "https://<user>-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/.

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.
