Wassenger + Meta Muse
Wassenger WhatsApp API: list connected numbers and their session health, send WhatsApp text messages, track delivery, and read chats, chat history and contacts of a number.
Prerequisites
See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:
WASSENGER_API_TOKEN
Step 1 — Get credentials
- In the Wassenger Web Console, open Developers → API Keys and copy or create a key into
WASSENGER_API_TOKEN. Use an owner or admin key: chat agents and supervisors cannot use the API. - Link your WhatsApp number in the console first (scan the QR code); a number that is not online cannot send.
- Start with
wassenger_list_numbers: itsid(24 hex characters) is thedevice_idfor the chat, contact and health tools.wassenger_get_number_healthexplains why a number is not sending.
A number linked by QR code runs a WhatsApp Web session, an unofficial channel that WhatsApp may restrict for bulk sending; numbers on the cloud connector use Meta's official API. wassenger_send_message sends a real message: confirm the recipient and the text first, and do not retry after it returns an id. Reading chats and chat history needs a Platform plan (Gateway plans are send-only and answer 403). Phone numbers are E.164 with + (+447911123456); lists page with page (from 0) and size.
Step 2 — Install the adapter
curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d
Step 3 — Add the connector in Muse
Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (
https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide showsYOUR_SERVER_ID.
Muse adds remote MCP servers as custom connectors and signs in to them with OAuth.
- In Muse, open Settings → Connectors and choose Add custom connector.
- Paste the MCP server URL
https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID. - Muse opens the AnythingMCP sign-in page: sign in and approve access.
- In a chat, ask Muse for something that needs the
Wassengertools.
You can also set it up from a chat, on the web, in the iOS and Android apps or in WhatsApp. Send Muse this message:
Create a Custom Connector for a new remote MCP server, then connect to it:
Name: AnythingMCP
Transport: remote streamable HTTP
URL: https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID
Auth: OAuth
Self-hosting? Use your instance's public HTTPS address instead of https://cloud.anythingmcp.com. Muse connects from Meta's cloud, so localhost does not work.

FAQ
Where is Muse available? Meta currently offers Muse in the US and Canada, on the web, in the iOS and Android apps and in WhatsApp.
Does Meta review this connector? No. Meta doesn't review custom connectors. Muse sees only the tools you switched on for this MCP server in AnythingMCP, and you can disconnect it anytime under Settings → Connectors.
