Setup
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
- Open
http://localhost:3000/connectors/storeand import the Billomat adapter - Enter your Billomat subdomain (e.g.,
mycompanyfrommycompany.billomat.net) and API key - Assign the connector to an MCP server
Connect Gemini
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.
Gemini CLI reads MCP servers from ~/.gemini/settings.json (on Windows %USERPROFILE%\.gemini\settings.json). Add:
{
"mcpServers": {
"anythingmcp": {
"httpUrl": "https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID",
"headers": { "X-API-Key": "YOUR_MCP_API_KEY" }
}
}
}
- Create an MCP API key in AnythingMCP under MCP Servers → your server → API keys, and paste it in place of
YOUR_MCP_API_KEY. - Save the file and restart
gemini. - Run
/mcpinside Gemini CLI (orgemini mcp listin your shell) —anythingmcpshould show as connected. - Start prompting — Gemini CLI can now call the
Billomattools.
Self-hosting with the quickstart above? Use your server's local endpoint http://localhost:4000/mcp/<server-id> as the URL.
