Harvest MCP integration
Logs hours to the right project, sends estimates from a scoping conversation, raises invoices and records payments, and sets new clients up to bill.
57actions available
Three actions you can hand over today
Every action runs live through MCP. Nothing to build, nothing to maintain.
Create invoice payment
Ayro records a new payment against an invoice. Agents document customer payments and update billing status.
Update invoice
Ayro modifies an invoice's details and amounts. Support teams adjust billing when corrections are needed.
Get invoice
Ayro retrieves the full details of a specific invoice. Agents answer customer billing questions accurately.
How businesses use Harvest + Ayro
Each card is one request a support team gets, and the Harvest actions Ayro runs to close it.
Log the hours without opening a timer
Ayro creates the time entry against the right project and task from what someone describes in chat, corrects an entry whose hours or notes were wrong, and reads back what has been logged this week.
Create Time EntryUpdate Time EntryList Time EntriesTurn a scoping conversation into an estimate
Ayro builds the estimate from the client and line items just agreed, sends it to the client as an estimate message, and reopens it later when the scope moves.
Create EstimateCreate Estimate MessageGet EstimateRaise the invoice and record what came back
Ayro creates the invoice from tracked time and expenses, sends the notification that puts it in front of the client, and records the payment against it once it clears.
Create InvoiceCreate Invoice MessageCreate Invoice PaymentStand up a new client ready to bill
Ayro registers the client, adds the contact who will receive the paperwork, and creates the project that time and expenses will be tracked against, so nothing is logged against the wrong container.

How it works
Get started in 3 steps
Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Ayro reads the Harvest actions it has and picks the ones a request needs.
Connect Harvest
Authorize the Harvest account your team already uses — one consent screen, no API keys, no mapping tables. Ayro can only do what you granted that account, and you can disconnect it at any time.
Tell your agent what you need
Describe the job the way you would hand it to a teammate. Ayro maps it to the Harvest actions that close it and chains as many as the request needs.
Watch it work
The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

FAQ
Everything else about Harvest
Setup, permissions, and the limits of what Ayro can do inside Harvest.
More than you might expect, and deliberately so. Delete Client only works on a client with no projects, invoices, or estimates attached; Delete Task only on a task with no time entries; Delete User only on a user with no time entries; and Delete Time Entry only on an entry that is not locked. Delete Invoice additionally requires administrator permissions.
