Invoice Ninja + Claude
Invoice Ninja: clients, invoices, quotes, recurring invoices, payments, products, expenses and projects. REST API v5 on Invoice Ninja's hosted service or your own instance, API-token auth.
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:
INVOICENINJA_URL, INVOICENINJA_API_TOKEN
Step 1 — Get credentials
Getting a token
- Sign in and open Settings → Account Management → API Tokens (on v5; on a self-hosted instance the same page exists).
- Create a token and put it in
INVOICENINJA_API_TOKEN. - Set
INVOICENINJA_URL. For the hosted service that ishttps://invoicing.co; for a self-hosted instance, your own root. No trailing slash and no/api/v1— the adapter appends it.
The header is X-API-TOKEN.
One token, one company. Invoice Ninja supports several companies per account, and the token is bound to the one it was created in. A second company needs a second token and a second connector.
…(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 Claude
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.
Recommended path — works on claude.ai web without editing any config file.
- In Claude, open Customize → Connectors.
- Click +, then Add custom connector.
- Enter a name, e.g.
Invoice Ninja, and the remote MCP server URLhttps://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID, then click Add. - Click Connect and sign in to AnythingMCP (OAuth) to allow access.
