How to Use the 4D MCP in Cursor

Q: Does Cursor allow 4D database modifications?

Yes, the agent can call updateentity or deleteentity if you authorize the action. You have full control over what the agent executes.

Q: Are 4D schema updates visible to Cursor?

Yes, run getcatalog whenever you change your database structure. This refreshes the context the agent uses to generate your code.

Cursor agent mode gives you direct access to 4D database records while you write code.

Cursor agent queries 4D records

When you are in Agent mode, Cursor can fetch live data using `list_entities`. It uses ORDA-style filters to grab exactly what you need for your current task. Your code gets built with real database output. No more writing mock data or guessing what the API returns.

Write 4D data from Cursor

The agent can execute `create_entity` or `update_entity` based on the code you just wrote. It translates your logic into a valid JSON payload for the database. This closes the loop between your schema design and your data storage. You define the structure, and the agent keeps the records in sync.

Navigate 4D catalogs in Cursor

Run `get_catalog` to let the agent index your database structure. It stores this context in the chat, so it understands the relationships between your DataClasses. This makes your refactoring tasks much faster. The agent knows the schema, so it suggests changes that actually work with your existing records.

Setup guide

Set up 4D 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 4D 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 4D transactions." If the MCP tools are loaded correctly, Cursor will call the 4D tools automatically. You can also check Settings → MCP for a green status indicator.

.cursor/mcp.json

{
  "mcpServers": {
    "4d-mcp": {
      "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    }
  }
