Harvest
for LuumenAI
Read Harvest clients, projects, and invoices. Bill the work as an approved step.
Connect Harvest and your team can ask about clients, projects, tasks, and time entries without opening the web app. Luumen reads the account over OAuth2 and answers in the terminal. When it is time to raise an invoice, create an expense, or send an estimate, the change is shown first and waits for your approval by default.

Questions
Authorize once with OAuth 2.0. Luumen lists the scopes each action needs before you approve the connection, and credentials never appear in the chat.
Read actions answer immediately. Anything that writes — create client, create client contact, create estimate, create estimate item category, and more — is shown as a plan and requires approval by default, including the 12 actions classified as destructive. Administrators configure that per tool, so you decide exactly which actions can ever run unattended.
You decide. Actions are granted per agent, skill, and team, and per environment — production is not staging. Read access can be broad while writes stay narrow.
Every call to Harvest — read or write, approved or declined — is recorded with the actor, the input, and the result, and can be linked to the ticket or change record.
