How do I find which tables are available?

Use the `get_catalog` tool. It will return a list of all DataClasses (tables) exposed through the REST API in your 4D Server.

Can I filter data based on specific conditions?

Yes. Use the `list_entities` tool and provide an ORDA-style filter string in the `$filter` parameter (e.g., "status = 'active' AND price > 100").

Does this support creating new records?

Absolutely. Use the `create_entity` tool by providing the DataClass name and a JSON string containing the field data for the new record.

About 4D MCP Server

Bridge your 4D Server with the world of AI Agents through the power of ORDA (Object Relational Data Architecture). This integration transforms your 4D database into an intelligent, queryable knowledge base, allowing your AI agent to explore structures and manage records through natural conversation. No more manual REST calls; your agent can now audit catalogs, run complex entity queries, and perform high-speed CRUD operations, ensuring your 4D data is always accessible and actionable within your AI workflows.

Cursor's Agent mode turns 4D into an in-editor superpower. Ask Cursor to generate code using live data from 4D and it fetches, processes, and writes. all in a single agentic loop. 6 tools appear alongside file editing and terminal access, creating a unified development environment grounded in real-time information.

What you can do

Database Exploration — Retrieve the full catalog of DataClasses (tables) and their attribute definitions (fields) to map your data structure.
Advanced Querying — Perform complex data lookups using filters, ordering, and expansion of related entities with ORDA syntax.
CRUD Operations — Create, read, update, and delete records across any exposed DataClass in your 4D environment.
Metadata Insights — Check server information, version, and database structure on the fly to ensure system integrity.
Structured Access — Interact with your data using the modern ORDA model, ensuring consistency, type safety, and security.

The 4D MCP Server exposes 6 tools through the Vinkius. Connect it to Cursor in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.

How to Connect 4D to Cursor via MCP

Why Use Cursor with the 4D MCP Server

Cursor AI Code Editor provides unique advantages when paired with 4D through the Model Context Protocol.

Agent mode turns Cursor into an autonomous coding assistant that can read files, run commands, and call MCP tools without switching context

Cursor's Composer feature can generate entire files using real-time data fetched through MCP. no copy-pasting from external dashboards

MCP tools appear alongside built-in tools like file reading and terminal access, creating a unified agentic environment

VS Code extension compatibility means your existing workflow, keybindings, and extensions all work alongside MCP tools

4D + Cursor Use Cases

Practical scenarios where Cursor combined with the 4D MCP Server delivers measurable value.

Code generation with live data: ask Cursor to generate a security report module using live DNS and subdomain data fetched through MCP

Automated documentation: have Cursor query your API's tool schemas and generate TypeScript interfaces or OpenAPI specs automatically

Infrastructure-as-code: Cursor can fetch domain configurations and generate corresponding Terraform or CloudFormation templates

Test scaffolding: ask Cursor to pull real API responses via MCP and generate unit test fixtures from actual data

4D MCP Tools for Cursor (6)

These 6 tools become available when you connect 4D to Cursor via MCP:

create_entity

Requires a JSON string representation of the data payload. Create a new record in the database

delete_entity

Delete a record from the database

get_catalog

Retrieve the database catalog definition

get_entity

Get a specific record by primary key

list_entities

Supports ORDA-style query parameters like $filter and $orderby for advanced lookups. Query records from a specific DataClass (table)

update_entity

Example Prompts for 4D in Cursor

Ready-to-use prompts you can give your Cursor agent to start working with 4D immediately.

"Show me the first 5 records from the 'Invoices' table."

"What tables (DataClasses) are exposed in my 4D catalog?"

"Create a new record in the 'Customers' table for 'John Doe' with email 'john@example.com'."

4D + Cursor FAQ

Common questions about integrating 4D MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design. tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
