# Lexware Office MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Lexware Office and the rest of your systems. It gives your agent 49 Lexware Office actions (30 reads, 17 writes and 2 that wait for a confirmation) and holds the Lexware Office credential itself, so the agent never does. It paces Lexware Office's limits and records every call.

Set up

## Connect Lexware Office 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 Lexware Office.
   API key. 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.
   - `api_key` Lexware API key (Lexware Office > Add-ons > Public API, https://app.lexware.de/addons/public-api)
   ```
   account { op: "connections.requirements", service: "lexware_office" }
   # 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: "lexware_office.articles.list" }
   # list and filter articles · read · 1 upstream call
   check { action: "lexware_office.invoices.create", input: { … } }
   # free: inputs, permissions, cost and confirmations, nothing sent
   ```

Try it

## Prompts to paste into Claude.

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

1. Read read
   Which Lexware Office invoices are more than 30 days overdue? Group them by customer with the total owed.
   calls `lexware_office.voucherlist.list`
2. Write write
   Create an invoice in Lexware Office. Show me exactly what you will send before you save it.
   calls `lexware_office.invoices.create`
3. Across systems read
   Which Lexware Office companies have invoices in ConnectWise PSA, and how many each?
   calls `lexware_office.contacts.list` `connectwise_manage.invoices.list`

Across your systems

## Lexware Office, joined to the rest of your business.

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

- Which Lexware Office companies have invoices in ConnectWise PSA, and how many each?
  `lexware_office.contacts.list` + `connectwise_manage.invoices.list`, on `crm.company` · [ConnectWise PSA](https://actionlake.com/connectors/connectwise-psa)
- Which Lexware Office companies have tickets in HubSpot CRM, and how many each?
  `lexware_office.contacts.list` + `hubspot_crm.tickets.list`, on `crm.company` · [HubSpot CRM](https://actionlake.com/connectors/hubspot-crm)

Also mapped by other connectors `crm.company` **227** `commerce.product` **109** `finance.invoice` **91**

ask

```
ask {
  intent: "which Lexware Office companies have invoices in ConnectWise PSA, and how many each",
  steps: [
    { action: "lexware_office.contacts.list", as: "co", input: {}, limit: 100, max_pages: 5 },
    { action: "connectwise_manage.invoices.list", as: "inv", input: {}, limit: 100, max_pages: 5 },
    { join: {
        left: "co",
        right: "inv",
        on: "crm.company",
        group_by: "co.name",
        select: ["co.name", "count(inv.id) as invoices"]
    } }
  ]
}
```

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

Governance for Lexware Office

## Destructive actions wait for a yes.

2 Lexware Office actions are destructive. These are all of them:

- Delete an article `lexware_office.articles.delete`
- Delete an event subscription `lexware_office.event_subscriptions.delete`

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 lexware_office.articles.delete confirm_policy: **human**

Delete an article?

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

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

In the console, or from an emailed signed link.

a key for this connector

```
account {
  op: "keys.create", name: "lexware-office-agent",
  allowed_actions: ["lexware_office.*"], cap_calls: 2000,
  confirm_policy: "human_for_writes",
  approval_rules: [
    { match: "lexware_office.articles.delete", approver: "lead@example.com" },
    { match: "lexware_office.event_subscriptions.delete", approver: "lead@example.com" }
  ]
}
```

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

Questions

## The Lexware Office MCP server, answered.

**Is there a Lexware Office MCP server for Claude?**

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 49 Lexware Office actions across articles, contacts, credit notes and delivery notes, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Lexware Office.

**What do I need to connect Lexware Office?**

Lexware API key (Lexware Office > Add-ons > Public API, https://app.lexware.de/addons/public-api). The free call account { op: "connections.requirements", service: "lexware_office" } lists exactly what to paste.

**Can an AI agent delete or change things in Lexware Office?**

Only if its key allows it, and only with an explicit confirmation. 2 Lexware Office actions are destructive, including delete an article and delete an event subscription. 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 Lexware Office API limit?**

actionlake paces every call to the limits in the Lexware Office service file: 2 calls a second per connection. Repeated reads are answered from cache (30 Lexware Office actions can be), which never reaches Lexware Office.

**What does a Lexware Office action cost?**

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (49 Lexware Office actions page). Cache hits, searches, dry runs and calls Lexware Office 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 Lexware Office API does it cover?**

The Lexware API v1 (api.lexware.io) at api.lexware.io. It is built from Lexware Office's documentation as read on 23 October 2026. 49 actions in 19 areas, each one in the signed service file (version 1.0.0).

**Can I combine Lexware Office with my other systems?**

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

**Does actionlake keep my Lexware Office data, and where?**

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to an hour, 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 Lexware Office 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.
