BuchhaltungsButler + Meta Muse
BuchhaltungsButler — German automated bookkeeping: postings, receipts, bank transactions, customers and suppliers. Every endpoint is a POST; auth is HTTP Basic (API client id and secret) plus an api_key field in the request body.
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:
BUCHHALTUNGSBUTLER_CLIENT_ID, BUCHHALTUNGSBUTLER_CLIENT_SECRET, BUCHHALTUNGSBUTLER_API_KEY
Step 1 — Get credentials
Getting credentials: BuchhaltungsButler needs three values, not one.
- In the web app open Einstellungen → API and create an API client. You receive an API client id and an API client secret: these are the HTTP Basic username and password.
- On the same page copy the API key for the client (Mandant) you want to reach. This is a separate value that travels in the body of every request.
- Set
BUCHHALTUNGSBUTLER_CLIENT_ID,BUCHHALTUNGSBUTLER_CLIENT_SECRETandBUCHHALTUNGSBUTLER_API_KEY.
…(continued in the in-app connector instructions)
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
BuchhaltungsButlertools.
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.
