How to Use the 4D MCP in Windsurf

Q: How do I connect the 4D MCP Server to Windsurf?

Open your /.codeium/windsurf/mcpconfig.json file and add the server configuration block under the mcpServers key. Alternatively, use the Cascade settings UI to paste the connection endpoint directly. Once added, click refresh in the MCP panel to let Cascade discover the tools.

Q: Can Windsurf Cascade run complex ORDA queries on my 4D database?

Yes, Cascade uses listentities to execute ORDA-style operations with $filter and $orderby parameters. You tell the editor what records you need, and it builds the query syntax automatically. It handles complex lookups across your tables without requiring manual SQL.

Q: How does Windsurf handle 4D schema updates?

Cascade calls the getcatalog tool to fetch the updated database blueprint. If you modify your tables on the 4D side, Cascade reads the new structure on its next run. This keeps your database interactions accurate without manual configuration files.

Q: What happens if a database write fails inside the editor?

The editor catches the error from createentity or updateentity and attempts to fix the payload. Cascade inspects the validation issue, adjusts the JSON schema, and retries the execution. You see the final successful state in your panel.

Explore 4D database schemas directly in Windsurf

`get_catalog` inspects your 4D structure so Cascade can construct accurate queries without manual schema mapping. This tool exposes all tables and fields directly to your workspace. Cascade uses this structural map to plan its next steps. Instead of guessing column names, your editor reads the definitions and writes exact filters on the first try.

Run ORDA-style queries inside your Windsurf workspace

`list_entities` lets Cascade search your 4D tables using native ORDA filters and ordering rules. The editor chains this tool with code generation to populate UI components with live data. You don't copy-paste raw JSON payloads anymore. Cascade handles the server round-trips behind the scenes, pulling exact datasets based on your natural language prompts.

Write and modify 4D records using this MCP Server

`create_entity` and `update_entity` execute database modifications directly from your workspace chat. These tools let Cascade write new records and patch existing ones using standard JSON payloads. If a write fails, Cascade reads the error, corrects the payload structure, and retries the operation. This loop happens entirely inside the editor without interrupting your coding flow.

Setup guide

Set up 4D MCP in Windsurf

Prerequisites

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

1

Open MCP configuration

Click the Cascade assistant icon in the sidebar, then click the hammer icon (🔨) at the top of the panel. Select "Configure" to open ~/.codeium/windsurf/mcp_config.json.
2

Add the 4D MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Refresh MCPs

Go back to the hammer icon (🔨) in Cascade and click "Refresh". Windsurf will detect the new server. No full restart is needed — the connection is hot-reloaded.
4

Verify in Cascade

Start a new Cascade conversation and ask something like "Show my 4D payment history." If connected, Cascade will call the 4D tools directly. You will see a green dot next to the server name in the MCP panel.
