Overview

Description from the maker (original English)

Unified messaging MCP server: WhatsApp, Instagram, Telegram, SMS, Messenger & email support inbox

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

Install

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

Before you install

  • Basic checks: 3 of 3 passed
  • Runs on the maker’s server: what you ask it goes through their server.
  • The registry lists no key to fill in.

What it can do

The server asks you to sign in before it lists its tools.

Common questions

Is Messaging safe?

It passed 3 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

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 (1.1.0) reached the registry 2 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

SendSeven MCP Server

The official Model Context Protocol (MCP) server for SendSeven - the unified messaging API platform for WhatsApp, Instagram DMs, Telegram, SMS, Messenger, Live Chat, and Email.

Connect your SendSeven account to Claude, ChatGPT, Gemini, Cursor, or any MCP-compatible AI assistant to manage your unified inbox, send omnichannel messages (WhatsApp, Instagram private replies, Telegram, SMS, Messenger, email), run marketing campaigns, staff a team chat bot, and search your knowledge base using natural language — all through your existing customer support and messaging API platform.

Quick Start

Option 1: Remote Server (Recommended)

No installation needed. Add to your AI client:

Claude Desktop (claude_desktop_config.json):

{

"mcpServers": { "sendseven": { "url": "https://mcp.sendseven.com/mcp", "auth": { "type": "oauth2", "authorizationUrl": "https://mcp.sendseven.com/authorize", "scopes": ["conversations:read", "messages:create", "contacts:read"] } } } }

Claude Code (.claude/settings.json):

{

"mcpServers": { "sendseven": { "url": "https://mcp.sendseven.com/mcp", "headers": { "Authorization": "Bearer YOUR_API_TOKEN" } } } }

ChatGPT (Settings > Connectors > Add custom connector):

MCP Server URL: https://mcp.sendseven.com/mcp

Authentication: OAuth

ChatGPT walks you through the OAuth consent + capability picker automatically — no config file needed.
Option 2: API Token (Developer Setup)

For developers and CI/CD pipelines, use a static API token:

  1. Generate an API token in SendSeven: Settings > API Tokens
  2. Configure your MCP client with the token as a Bearer header
Option 3: Self-Hosted
git clone https://github.com/SendSeven-GmbH/sendseven-mcp-server.git

cd sendseven-mcp-server npm install npm run dev # Runs on localhost:8787

Available Tools

Tools are registered based on the capabilities selected during the OAuth connection. The table below groups tools by function for readability; the OAuth consent screen groups the same 69 tools into 12 coarser capability groups (Conversations, Messaging, Email, Contacts, Campaigns, Knowledge Base, Webhooks, Team Chat Bots, Agent Builder, Knowledge Base Authoring, Contact Data Model, Flows) — granting a group grants every tool listed under it below. Full parameter reference: docs/TOOLS.md.

Build an AI agent from your assistant

The Agent Builder lets your own AI assistant create, test and publish a SendSeven Conversational Agent. Ask it to use the build_conversational_agent prompt: it interviews you (website, goals, knowledge, persona, skills, hand-off), writes the knowledge base documents, FAQ and skills, tests the draft and shows the AI credits used. Agents are always created as unpublished, inactive drafts; publishing and switching them on needs your explicit yes (confirm=true). Reference guides are exposed as MCP resources (sendseven://guides/...). If a permission was not granted when you connected, the assistant tells you which capability is missing and asks you to reconnect and approve it (check_permissions).

Authentication

OAuth 2.0 + PKCE (Recommended)

The server is a full OAuth 2.0 authorization server for MCP clients, with Dynamic Client Registration (DCR) so you don't need to pre-register an app:

EndpointURL
MCP endpointhttps://mcp.sendseven.com/mcp (Streamable HTTP)
Authorizationhttps://mcp.sendseven.com/authorize
Tokenhttps://mcp.sendseven.com/token
Dynamic Client Registrationhttps://mcp.sendseven.com/register

Most MCP clients (Claude, Cursor, etc.) discover these automatically from https://mcp.sendseven.com/mcp and only need the base URL — see the claude-desktop.json example above and the examples/ directory. For a client that needs the flow spelled out:

  1. The client registers itself via DCR (POST /register) and receives a client_id.
  2. The client sends the user to /authorize with a PKCE code_challenge and the requested scopes.
  3. The user logs in with their SendSeven account and approves the requested scopes on the consent screen.
  4. The authorization code is redeemed at /token (with the PKCE code_verifier) for an access + refresh token.
  5. The access token is sent as a Bearer token on every MCP request; the server refreshes it automatically using the refresh token.

Users can only grant scopes their SendSeven role already has - a Support Agent without campaign permissions never sees campaign tools, regardless of what the client requests.

The connected account acts as that member: if a workspace admin limited the member's contact visibility ("only reachable contacts"), contact tools only return the contacts that member can reach, and other contacts behave as not found.

API Tokens (Developer)

Generate a token in SendSeven's dashboard (Settings > API Tokens) and pass it as a Bearer header — simpler for CI/CD and scripts, but it doesn't auto-refresh and must be rotated manually.
