# Harvest MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Harvest and the rest of your systems. It gives your agent 211 Harvest actions (93 reads, 90 writes and 28 that wait for a confirmation) and holds the Harvest credential itself, so the agent never does. It paces Harvest's limits and records every call.

[Connect Harvest free](https://actionlake.com/console?start=sandbox) [See pricing](https://actionlake.com/pricing)

100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

`claude mcp add --transport http actionlake https://connect.actionlake.com/mcp`

the first call

```
do {
  action: "harvest.invoices.list",
  intent: "check which Harvest account is connected"
}
# List all invoices · read · 1 upstream call
```

- 211 actions in one signed file
- 93 read look, never change
- 90 write create and update
- 28 wait for a yes destructive, confirmed first

Set up

## Connect Harvest in three steps.

1. 01
   ### Add actionlake to Claude.
   Run the command once in Claude Code; its consent page can create a free sandbox: 100,000 calls a month, no card. In the Claude app, add a custom connector with the URL below and paste your key on the consent page. Creating a new sandbox from the Claude app is not yet tested by us.
   `https://connect.actionlake.com/mcp`
2. 02
   ### Connect Harvest.
   Header credentials. No consent screen: your agent can connect it for you, but the key then passes through your chat. To keep it out of the model's context, paste it in the console instead. actionlake stores what you paste write-only, sealed under your tenant's key.
   - `access_token` Harvest access token: a Personal Access Token from https://id.getharvest.com/developers (Create new personal access…
   - `account_id` Harvest Account ID: shown beside the token on https://id.getharvest.com/developers (or returned by…
   ```
   account { op: "connections.requirements", service: "harvest" }
   # free: exactly what to paste, and what is found for you
   ```
3. 03
   ### Make the first call. Check before a write.
   Ask in plain words; Claude picks the action. Before anything changes, `check` validates the call and prices it, for free.
   ```
   do    { action: "harvest.invoices.list" }
   # list all invoices · read · 1 upstream call
   check { action: "harvest.invoices.create", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

Top actions

## The Harvest API, shaped for agents.

The ids your agent types, what each does, and the one name it shares with other systems. 56 of Harvest's 57 action names are shared with at least one other connector, so an agent learns them once.

| Action | What it does | Effect | Same name in |
| --- | --- | --- | --- |
| `harvest.invoices.list` List all invoices | List all invoices. | read | `finance.invoice.list` 101 connectors |

Try it

## Prompts to paste into Claude.

Each one names the Harvest actions it will call, so you know what it reads and what it changes before you send it.

1. Read read
   Which Harvest invoices are more than 30 days overdue? Group them by customer with the total owed.
   calls `harvest.invoices.list`
2. Write write
   Create a free-form invoice in Harvest. Show me exactly what you will send before you save it.
   calls `harvest.invoices.create`
3. Across systems read
   For each customer, how many invoices are in Harvest and how many tickets in ConnectWise PSA?
   calls `harvest.invoices.list` `connectwise_manage.tickets.list`

Across your systems

## Harvest, joined to the rest of your business.

One `ask` fetches from Harvest and another system, joins the rows on the same customer on our side, and hands your agent the answer, not every row.

- For each customer, how many invoices are in Harvest and how many tickets in ConnectWise PSA?
  `harvest.invoices.list` + `connectwise_manage.tickets.list`, on `crm.company` · [ConnectWise PSA](https://actionlake.com/connectors/connectwise-psa)
- For each customer, how many invoices are in Harvest and how many tickets in HubSpot CRM?
  `harvest.invoices.list` + `hubspot_crm.tickets.list`, on `crm.company` · [HubSpot CRM](https://actionlake.com/connectors/hubspot-crm)

Also mapped by other connectors `identity.user` **517** `crm.company` **227** `crm.contact` **192** `identity.current_user` **142** `work.project` **116** `identity.role` **107** `work.task` **105** `finance.invoice` **91**

ask

```
ask {
  intent: "for each customer, how many invoices are in Harvest and how many tickets in ConnectWise PSA",
  steps: [
    { action: "harvest.invoices.list", as: "inv", input: {}, limit: 100, max_pages: 5 },
    { action: "connectwise_manage.tickets.list", as: "tix", input: {}, limit: 100, max_pages: 5 },
    { join: {
        left: "inv",
        right: "tix",
        on: "crm.company",
        group_by: "inv.company_name",
        select: ["inv.company_name", "count(inv.id) as invoices", "count(tix.id) as tickets"]
    } }
  ]
}
```

Example. Run it through check first: it validates the steps and prices them, and it is free.

Governance for Harvest

## Destructive actions wait for a yes.

28 Harvest actions are destructive. These are all of them:

- Delete an invoice `harvest.invoices.delete`
- Delete an estimate `harvest.estimates.delete`
- Delete an expense `harvest.expenses.delete`
- Delete a task `harvest.tasks.delete`
- Delete a project `harvest.projects.delete`
- Delete a user `harvest.users.delete`
- Delete a time entry `harvest.time_entries.delete`
- Delete a contact `harvest.contacts.delete`
- Delete a client `harvest.clients.delete`
- Delete a role `harvest.roles.delete`
- Delete an invoice payment `harvest.invoice_payments.delete`
- Delete a time off policy `harvest.pto_types.delete`
- Delete a custom role `harvest.custom_roles.delete`
- Delete a saved report `harvest.saved_reports.delete`
- Disconnect from e-invoicing `harvest.e_invoicing.disconnect`
- Delete an invoice message `harvest.invoice_messages.delete`
- Delete a task assignment `harvest.task_assignments.delete`
- Delete a user assignment `harvest.user_assignments.delete`
- Delete an estimate message `harvest.estimate_messages.delete`
- Delete an expense category `harvest.expense_categories.delete`
- Delete a user mapping `harvest.gusto_user_mappings.delete`
- Delete a holiday calendar `harvest.pto_holiday_calendars.delete`
- Deactivate a work schedule `harvest.pto_work_schedules.deactivate`
- Delete an invoice item category `harvest.invoice_item_categories.delete`
- Delete an estimate item category `harvest.estimate_item_categories.delete`
- Delete a holiday calendar entry `harvest.pto_holiday_calendar_entries.delete`
- Delete a time entry’s external reference `harvest.time_entries.delete_external_reference`
- Cancel a time off request `harvest.pto_requests.cancel`

A destructive action runs only with `confirm: true`. Under the `human` policy the agent cannot confirm for itself: the run stops until a named person approves, in the console or from a signed link in an email. The cap on a key is refused before the call is sent, never after.

do harvest.invoices.delete confirm_policy: **human**

Delete an invoice?

**intent:** the user asked me to delete an invoice

run suspended · waiting for a named person · key _harvest-agent_ cannot confirm itself

In the console, or from an emailed signed link.

a key for this connector

```
account {
  op: "keys.create", name: "harvest-agent",
  allowed_actions: ["harvest.*"], cap_calls: 2000,
  confirm_policy: "human_for_writes",
  approval_rules: [
    { match: "harvest.invoices.delete", approver: "lead@example.com" },
    { match: "harvest.estimates.delete", approver: "lead@example.com" },
    { match: "harvest.expenses.delete", approver: "lead@example.com" }
  ]
}
```

Illustrative. Scoped to Harvest only, capped at 2,000 upstream calls, every write confirmed, and the destructive ones approved by a named person.

Cost

## What Harvest costs on actionlake.

Questions

## The Harvest MCP server, answered.

**Is there a Harvest MCP server for Claude?**

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 211 Harvest actions across reports, pto requests, time entries and invoice messages, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Harvest.

**What do I need to connect Harvest?**

Harvest access token: a Personal Access Token from https://id.getharvest.com/developers (Create new personal access… and Harvest Account ID: shown beside the token on https://id.getharvest.com/developers (or returned by…. The free call account { op: "connections.requirements", service: "harvest" } lists exactly what to paste.

**Can an AI agent delete or change things in Harvest?**

Only if its key allows it, and only with an explicit confirmation. 28 Harvest actions are destructive, including delete an invoice, delete an estimate and delete an expense. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

**Will an AI agent use up my Harvest API limit?**

actionlake paces every call to the limits in the Harvest service file: 100 calls per 15 seconds per connection. Repeated reads are answered from cache (93 Harvest actions can be), which never reaches Harvest.

**What does a Harvest action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (211 Harvest actions page). Cache hits, searches, dry runs and calls Harvest refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

**Which Harvest API does it cover?**

The Harvest API v2 (REST, documented at help.getharvest.com/api-v2) at api.harvestapp.com. It is built from Harvest's documentation as read on 22 October 2026. 211 actions in 48 areas, each one in the signed service file (version 1.0.0).

**Can I combine Harvest with my other systems?**

Yes. ask joins Harvest to ConnectWise PSA or HubSpot CRM on the same customer and returns the answer rather than every row. Harvest maps crm.company, which 227 other connectors also map.

**Does actionlake keep my Harvest data, and where?**

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Harvest credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

**Which AI clients can use it?**

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
