What if creating an invoice felt as natural as describing the work you completed?
Today we are releasing Quento Agent Skills: an open, installable skill that lets supported AI agents work with your Quento account in plain language.
Use it from Codex, Claude Code, Cursor, VS Code, Goose, Amp and other Agent Skills-compatible clients. Ask your agent to list recent invoices, prepare a draft, find a client, check paid revenue or submit an invoice to KSeF — without leaving your current workspace.
Ask for the outcome, not the clicks
The skill understands complete invoicing workflows, so you can write requests such as:
- “Show my three latest invoices.”
- “Create a draft invoice for 10 hours of consulting at 200 PLN per hour.”
- “Add the client with NIP 5261040828.”
- “How much revenue did we receive this month?”
- “Mark invoice 001/08/2026 as paid.”
- “Submit this invoice to KSeF.”
Your agent can use Quento to work with invoices, clients, seller companies, products, bank accounts, payment status, analytics and KSeF.
Built-in invoicing guardrails
This is more than a list of API calls. The skill teaches the agent how Quento works and how to avoid common accounting mistakes:
- it resolves the correct client, company or invoice before making a change;
- a supplied NIP or EU VAT number is checked against the company registry before creating a client;
- invoice actions follow the draft, issued and paid states;
- ambiguous payment instructions are clarified before recording a payment;
- revenue and outstanding amounts remain separated by currency;
- when a PLN company receives a price in USD or another currency, the agent retrieves a fresh, sourced exchange rate and confirms whether to keep the foreign-currency invoice or convert the prices — it never silently relabels the amount.
Secure connection through MCP OAuth
Quento Agent Skills connects through Quento's official MCP server using standard browser-based OAuth. There are no API keys to copy into prompts or configuration files.
Your MCP client stores and renews its authorization, while Quento keeps the same account and access controls you already use.
Install with one command
npx skills add DeliveristsIO/quento-skills
The installer detects compatible agents. The skill then guides your agent through connecting https://quento.app/mcp; you only need to sign in to Quento and approve access in the browser.
Claude Code users can also install the Quento plugin, which bundles the skill and MCP connection:
/plugin marketplace add DeliveristsIO/quento-skills
/plugin install quento@deliverists
The skill is publicly available on GitHub, so teams can inspect the workflows and always see exactly what their agent has been taught.
