The headache of tracking site financials.
Today, managing project costs means switching between the physical job site clipboard, your email inbox, and the complex ERP system. You copy dates, you type in labor hours, and then you have to manually find the correct project ID for every single expense item before hitting 'save.' It's a cycle of data entry and cross-referencing that wastes half your day.
With this MCP connected through Vinkius, you just talk to your agent. You tell it what happened—'We spent €200 on lumber today for Project Alpha.' The AI handles the rest: finding the correct project ID, recording the cost transaction using `create_cost_transaction`, and logging it against the right date. It’s immediate, accurate bookkeeping.
Using the Exact Online Bouw MCP makes time tracking simple.
Before this, every single shift ended with a pile of paper timesheets that required an administrator to manually enter each employee's hours into the system. Then they had to check against multiple project codes just to make sure everything matched up for payroll.
Now, you simply tell your agent: 'Log 8 hours for John Doe on Project Beta today.' The MCP executes `create_time_transaction` instantly. It’s a single command that handles the entire labor record process.
What you can do with this MCP connector
Need to manage site financials while running around? This connector links your AI agent directly to your Exact Online Bouw account, letting you handle complex construction accounting through simple conversation. Forget logging into multiple tabs or manually entering spreadsheet data. You can ask your agent things like, 'How much did the City Tower Renovation cost last month?' and get an immediate, accurate answer based on recorded expenses.
It’s about taking full control of project budgets and time tracking using only natural language commands. By connecting it through Vinkius, you give your AI client access to a centralized catalog of tools, making this MCP just one part of a much bigger workflow puzzle.

How Exact Online Bouw MCP Works
- 1 Subscribe to this MCP and retrieve your Access Token, Division ID, and Region from the Exact Online App Center.
- 2 Connect these credentials to your preferred AI client or agent through the Vinkius platform.
- 3 Ask your agent a question (e.g., 'Log 4 hours for John on Project X') and the MCP handles the transaction in the background.
The bottom line is you treat complex accounting tasks like chatting with an expert assistant, letting the AI handle all the backend database calls.
Who Is Exact Online Bouw MCP For?
Project Managers who are tired of switching between the construction site and the ERP system to log hours. Finance teams that need project-specific cost visibility without running complex SQL queries.
You use the agent to list projects, check progress against budgets, and quickly register site hours using natural language commands.
You monitor project-specific costs by listing cost transactions or retrieving account directories for month-end reporting.
You verify employee assignments and check the full Work Breakdown Structure (WBS) to ensure all deliverables are accounted for.
What Changes When You Connect
- Stop manually tracking hours. Use
create_time_transactionto log labor directly from your conversation, instantly updating payroll and cost records. - Never lose track of spending again. By using
create_cost_transaction, you register expenses against a project right when they happen, keeping budgets accurate. - Get the full picture immediately. Running
list_project_wbsshows you every deliverable required for a job, keeping the scope clear for everyone. - Speed up reporting. Instead of running complex queries, simply ask to
list_cost_transactionsorlist_time_transactionsand get an auditable list. - Save time on setup. You can use
create_projectwith a single prompt instead of navigating through the initial project creation forms.
Real-World Use Cases
Closing out site hours after a meeting
A supervisor needs to log 6 hours for three different workers on three different tasks across one project. Instead of logging into the system and running multiple transactions, they just tell their agent: 'Log 2 hours for employee A, 3 hours for B, and 1 hour for C today.' The agent uses create_time_transaction repeatedly to complete the task.
Budget check before buying materials
The PM knows a material purchase is needed but needs to confirm funds. They ask, 'What's the budget remaining for Project X?' The agent uses list_project_hour_budgets and cross-references costs via list_cost_transactions to give a quick answer.
Starting a new contract
A sales lead signs a client agreement. Instead of having the administrator manually create the project, the PM tells their agent: 'Start a new project for ABC Corp.' The agent calls create_project and returns the ID so the work can begin.
Audit trail cleanup
The finance team needs to verify if all labor costs were properly attached. They ask the agent to 'Show me all hours logged for last quarter.' The agent uses list_time_transactions and provides an immediate, searchable list.
The Tradeoffs
Listing projects repeatedly
Asking the agent to 'List projects' five times in one session because you think it will give different data each time. This wastes tokens and slows down your workflow.
→
Use list_projects once at the start of your task, then reference the resulting IDs (like guid_1) when performing specific actions like logging hours with create_time_transaction. Keep your calls sequential.
Manually linking costs to projects
Finding a cost invoice and having to manually enter every detail into the ERP, checking fields for project ID, date, etc.
→
Just tell the agent: 'Register a €500 expense for Project Y today.' The agent handles the create_cost_transaction with minimal input from you.
Overlooking employee data
Trying to log time without knowing if the employee ID is current or correct, leading to failed transactions.
→
Always start by running list_employees. This ensures your agent has the most up-to-date directory of IDs before you attempt any transaction.
When It Fits, When It Doesn't
Use this MCP if your daily work revolves around tracking money and time against defined construction projects. If you need to know 'how much was spent' or 'who worked when,' this is your tool. Don't use it if you only need general communication (use a messaging client) or if the project scope hasn't been formalized yet (you must first run list_projects to see what's active). If you just need to read raw financial reports without triggering transactions, look for a dedicated reporting tool instead; this MCP is designed for actionable data input.
Common Questions About Exact Online Bouw MCP
How do I find my Division ID? +
Use the get_me tool to retrieve your current authenticated user profile and the active Division ID associated with your account.
Can I register hours for a specific date? +
Yes! The create_time_transaction tool requires a Date parameter in YYYY-MM-DD format to log work entries accurately.
Which regions are supported for Exact Online? +
Common regions include 'nl', 'be', 'com', 'co.uk'. Check your login URL (e.g., start.exactonline.nl) to confirm your specific region code.
Before I run `list_projects`, what permissions do I need for my AI client? +
You must grant read and write access to project data in your Exact Online App Center. This MCP needs these specific scopes to function, allowing your agent to not only list projects but also create new ones using the create_project tool.
If I use `list_accounts`, how do I ensure the CRM account is active for billing? +
The listing provides a complete directory of your accounts, showing their current status. Always cross-reference the returned data with your internal records to confirm if an account has been flagged as inactive or archived before attempting any transactions.
When running `create_cost_transaction`, what happens if I forget a required Project ID? +
The system throws a validation error, requiring you to include a valid project identifier. Your agent will flag this specific missing data point and prompt you to retrieve the correct ID using the list_projects tool before retrying.
What information does `list_project_wbs` provide beyond just task names? +
It returns a full, hierarchical structure of your deliverables. This allows you to see which activities roll up into larger project phases and gives you the necessary context for accurate cost tracking.
After I run `get_project`, what steps should I take if I need to add employee hours? +
The detailed project data provides all necessary IDs. You then pass the Project ID, along with the employee and activity details, directly into the create_time_transaction tool. This logs the time against the specific project record.
