It gives your agent 1,043 Exact Online actions (689 reads, 256 writes and 98 that wait for a confirmation) and holds the Exact Online credential itself, so the agent never does. It paces Exact Online's limits and records every call. Connecting Exact Online needs your own Exact Online OAuth app and one admin sign-in.

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 Exact Online. OAuth 2.0, authorization code. You register your own OAuth app with Exact Online, an admin signs in once, and you paste the app's client id and secret and the tokens from that sign-in; actionlake renews the access token from then on. actionlake stores what you paste write-only, sealed under your tenant's key. Before the first sign-in, Exact Online needs an OAuth app of your own, registered in its developer portal. actionlake has no Exact Online app to lend you. - `access_token` Access token from one sign-in with your own OAuth app - `refresh_token` Refresh token from the same sign-in; the access token is renewed from it - `client_id` Exact Online App Center client ID (register the app for your country site; set the connection's `host` to that site,… - `client_secret` Exact Online App Center client secret - `division` Your Exact Online division - `host` Where your Exact Online lives: your host ``` account { op: "connections.requirements", service: "exact_online" } # 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: "exact_online.salesinvoice_sales_invoices.list" } # list sales invoices (salesinvoice) · read · 1 upstream call check { action: "exact_online.salesinvoice_sales_invoices.create", input: { … } } # free: inputs, permissions, cost and confirmations, nothing sent ``` Exact Online at a glance **Sign-in** OAuth 2.0, authorization code.

Questions ## The Exact Online MCP server, answered. **Is there an Exact Online MCP server for Claude?** Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 1,043 Exact Online actions across project, manufacturing, CRM and financial, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Exact Online. **What do I need to connect Exact Online?** Your own Exact Online OAuth app, registered with Exact Online (its client id and client secret), and the access and refresh tokens from one admin sign-in. actionlake has no Exact Online app of its own, so this is not a one-step consent. actionlake renews the access token as it expires. Plus your division and your host. The free call account { op: "connections.requirements", service: "exact_online" } lists exactly what to paste. **Can an AI agent delete or change things in Exact Online?** Only if its key allows it, and only with an explicit confirmation. 98 Exact Online actions are destructive, including delete sales invoices (SalesInvoice), delete quotations (CRM) and delete purchase invoices (Purchase). 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 Exact Online API limit?** actionlake paces every call to the limits in the Exact Online service file: 60 calls a minute and 5,000 a day per connection. Repeated reads are answered from cache (689 Exact Online actions can be), which never reaches Exact Online. **What does an Exact Online action cost?** One upstream call, the only unit actionlake bills. A list that pages bills one call per page (412 Exact Online actions page). Cache hits, searches, dry runs and calls Exact Online 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 Exact Online API does it cover?** The Exact Online REST API v1 (OData v2) at start.exactonline.nl by default, or the base URL set when you connect. It is built from Exact Online's documentation as read on 23 October 2026. 1,043 actions in 35 areas, each one in the signed service file (version 1.0.0). **Can I combine Exact Online with my other systems?** Yes. ask joins Exact Online to ConnectWise PSA or HubSpot CRM on the same customer and returns the answer rather than every row. Exact Online maps crm.company, which 227 other connectors also map. **Does actionlake keep my Exact Online data, and where?** actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 15 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 Exact Online 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. ## More connectors like Exact Online Shares the most action names with - [ERPNext (Frappe) 74](https://actionlake.com/connectors/erpnext-frappe) - [Holded 62](https://actionlake.com/connectors/holded) - [Moneybird 54](https://actionlake.com/connectors/moneybird) - [Tripletex 53](https://actionlake.com/connectors/tripletex) - [Epicor Kinetic 52](https://actionlake.com/connectors/epicor-kinetic) - [SAP Business One 50](https://actionlake.com/connectors/sap-business-one) Joins with, on shared entities - [HaloPSA 6](https://actionlake.com/connectors/halopsa) - [Microsoft Dynamics 365 5](https://actionlake.com/connectors/microsoft-dynamics-365) - [Zuper 5](https://actionlake.com/connectors/zuper) - [Kaseya BMS 5](https://actionlake.com/connectors/kaseya-bms) - [Zoho CRM 5](https://actionlake.com/connectors/zoho-crm) - [ConnectWise PSA 4](https://actionlake.com/connectors/connectwise-psa) Browse - [All Accounting & finance connectors](https://actionlake.com/connectors/category/accounting-and-finance) - [All connectors](https://actionlake.com/connectors) - [How actionlake compares](https://actionlake.com/compare) actionlake is independent.
