Show HN: InvoiceMCP – Let AI create and manage invoices directly

InvoiceMCP is an MCP server that gives AI tools (Claude, Windsurf, Cursor, etc.) direct access to invoicing systems.

Instead of stopping to open an app, I can stay inside Claude and say:

“Invoice Acme for API integration work – $3500”

It creates the invoice, generates the PDFs, handles everything. No context switch.

The bigger idea: as AI agents handle more end-to-end workflows, they’ll need billing systems they can talk to programmatically — without human intervention. That’s what InvoiceMCP provides.

Current features:

Natural language invoice creation

Client lookup + management

Payment tracking

Bulk + multi-company support

Full MCP API + server docs
