Free hosted MCP for Codex invoice workflows, with OAuth and free invoicing apps.

Pocket Invoice MCP is a free hosted connection for Codex to create and manage invoices, estimates, receipts and purchase orders through OAuth and company-scoped permissions. Export business documents as PDFs and work with client and item records. Sending is off by default and requires confirmation for each document; recording a payment does not charge customers or move money. Pocket Invoice also provides free invoicing on web, iOS and Android, with multiple companies and document templates. There is no paid plan or trial; account document and storage limits apply. External AI providers may charge separately.
