Overview

Description from the maker (original English)

WhatsApp CRM for AI agents: search contacts, read chats, manage the sales pipeline, send messages.

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: Marketing & social media
  • 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 chatflow https://valuable-sockeye-14.eu-west-1.convex.site/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "chatflow": {
      "url": "https://valuable-sockeye-14.eu-west-1.convex.site/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.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "chatflow": {
      "type": "http",
      "url": "https://valuable-sockeye-14.eu-west-1.convex.site/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

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

  • Authorization secret required HTTP header
    Bearer . Create one in ChatFlow → Settings → AI agents (MCP).

Common questions

Is Chatflow 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 (1.0.0) reached the registry 4 months 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: MCP YouTube Transcript, Google Analytics MCP, BibiGPT YouTube Video Summarizer

ChatFlow MCP

Connect your AI agent to your WhatsApp CRM.

ChatFlow is a WhatsApp/Telegram/Instagram CRM for small teams — a shared inbox, a drag-and-drop sales pipeline, AI auto-replies, and broadcast campaigns. This is its hosted MCP (Model Context Protocol) server: point Claude, Claude Code, Cursor, or any MCP-compatible agent at your workspace and it can search contacts, read conversations, manage your pipeline, and — when you allow it — send messages.

  • Endpoint: https://valuable-sockeye-14.eu-west-1.convex.site/mcp
  • Transport: Streamable HTTP (stateless)
  • Auth: Authorization: Bearer — create one in ChatFlow → Settings → AI agents (MCP)

Quick start

  1. In ChatFlow, open Settings → AI agents (MCP) (workspace owner) and click Create API key. Copy it — it's shown once. Optionally give it an expiry.
  2. Add the server to your client:

Claude Code

claude mcp add --transport http chatflow \

https://valuable-sockeye-14.eu-west-1.convex.site/mcp \ --header "Authorization: Bearer cfk_YOUR_KEY"

Claude.ai / Claude Desktop — Settings → Connectors → Add custom connector → paste the endpoint URL and set the Authorization: Bearer cfk_YOUR_KEY header.

Cursor — .cursor/mcp.json:

{

"mcpServers": { "chatflow": { "url": "https://valuable-sockeye-14.eu-west-1.convex.site/mcp", "headers": { "Authorization": "Bearer cfk_YOUR_KEY" } } } }

Full setup and troubleshooting: docs/setup.md.

Tools

ToolWhat it does
search_contactsFind contacts by name/phone substring
list_conversationsRecent chats with previews, unread counts, CRM fields
get_conversationOne chat: contact, notes, deal value, recent messages
list_pipelineKanban columns with the leads in each stage
move_conversationMove a lead to a pipeline column
update_leadSet notes / deal value on a conversation
create_contactCreate a WhatsApp contact + conversation from a phone number
send_messageSend a text to the customer (opt-in — see below)
get_usageSubscription tier, limits, current monthly usage

Read tools are annotated read-only; send_message is annotated as a world-affecting write so well-behaved clients confirm before calling it.

Sending is opt-in

send_message messages a real customer, so it's off by default. The workspace owner enables it with the "Allow agents to send messages" toggle in Settings. While off, agents can read everything and draft replies, but every send is rejected with a message explaining the toggle. When on, agent sends count toward your monthly quota, appear in the inbox with the AI badge, pause the auto-reply assistant on that chat (so two AIs never answer at once), and support an idempotencyKey so a retry can't double-send.

Prompt-injection note: message text and notes an agent reads are written by your customers. Keep the send toggle off unless you trust the agent driving it.
