How to Use the Karbon MCP in Cursor

Q: Can Cursor update Karbon work items while I code?

It can. The agent uses updateworkitem to push changes back to the API. You can watch it modify a project status while testing your integration.

Q: How does Cursor differentiate between Karbon organizations and people?

It calls specific endpoints. The agent runs listorganizations for business entities and listpeople for individual contacts, keeping the data cleanly separated in your code.

Real work items in Cursor

This MCP Server connects your editor directly to your accounting firm's live database. Instead of mocking up test data, Cursor runs `list_work_items` to pull actual project structures right into the script you are writing. When you need to test a specific payload, the agent calls `get_work_item` or `list_work_tasks`. It sees the exact JSON schema returned by the API and writes your integration code to match it perfectly.

Automate client records

Writing sync scripts for CRM data usually means guessing at field names. Cursor uses `get_contact` and `list_contact_notes` to inspect real client records before drafting the logic. You can tell the editor to build a function that registers new leads. It will test the logic by firing `create_contact` with the required name and type, ensuring your code works before you deploy it.

Query staff and entities

Building internal dashboards requires an accurate map of your staff and clients. Cursor hits `list_users` to pull your firm's active roster and formats that data into your frontend components. It handles the client side just as easily. The agent runs `list_organizations` and `list_people` to grab separate entity types, letting you code filtering logic based on actual firm data.

Setup guide

Set up Karbon MCP in Cursor

Prerequisites

Cursor installed (macOS, Windows, or Linux)
Active Vinkius subscription with a valid endpoint token

1

Open MCP Settings

Go to Cursor Settings → MCP or open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P) and search for "MCP: Add Server".
2

Add the Karbon MCP

Cursor will create or open .cursor/mcp.json in your project root. Paste the JSON snippet on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Enable Agent mode

Open Composer (Cmd+I / Ctrl+I) and switch to Agent mode using the dropdown at the top. MCP tools are only available in Agent mode.
4

Verify the connection

Ask Cursor something like "List my recent Karbon transactions." If the MCP tools are loaded correctly, Cursor will call the Karbon tools automatically. You can also check Settings → MCP for a green status indicator.
