How to create and send invoices with Claude (MCP guide)
Already work with Claude? Run your invoicing by chatting. Here's how Invco's MCP integration lets Claude create clients, build invoices and send them.

What is MCP, and why it matters for invoicing
MCP (Model Context Protocol) is an open standard that lets AI assistants like Claude connect to real tools and take real actions. Because Invco exposes its features through a built-in MCP server, Claude doesn't scrape a screen or guess — it calls Invco's own actions, with your permission.
That means accurate invoices, on your real templates, with your real client data, sent from your real email.
How to set it up
Getting Claude connected to Invco takes a couple of minutes:
- Create an Invco account (plans start at $10 a month) and add your business details and a template.
- Generate your personal MCP key in Settings → MCP access.
- Add Invco's MCP server to Claude with that key.
- Ask Claude to create a client or an invoice — it's connected to your account only.
What you can ask Claude to do
Once connected, you can run invoicing in plain English:
- “Create a client called Northwind Traders.”
- “Invoice Acme for the June retainer of $650 on my Modern template and email it.”
- “Mark invoice INV-0042 as paid.”
- “Which of my invoices are overdue?”
