What is the 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.

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.

How it works

  1. Subscribe to this server
  2. Enter your 4D Server Base URL and Credentials
  3. Start querying and managing your 4D database through Claude, Cursor, or any MCP-compatible client

Who is this for?

  • 4D Developers — quickly audit data and test queries using natural language commands without custom code.
  • Data Analysts — retrieve specific data subsets for reporting without writing manual HTTP requests or SQL.
  • Business Admins — manage application records and look up information across tables easily from a single chat interface.
  • Systems Integrators — verify REST API exposure and data availability in real-time during development.

Built-in capabilities (6)

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)

Why OpenAI Agents SDK?

The OpenAI Agents SDK auto-discovers all 6 tools from 4D through native MCP integration. Build agents with built-in guardrails, tracing, and handoff patterns. chain multiple agents where one queries 4D, another analyzes results, and a third generates reports, all orchestrated through Vinkius.

  • Native MCP integration via MCPServerSse, pass the URL and the SDK auto-discovers all tools with full type safety

  • Built-in guardrails, tracing, and handoff patterns let you build production-grade agents without reinventing safety infrastructure

  • Lightweight and composable: chain multiple agents and MCP servers in a single pipeline with minimal boilerplate

  • First-party OpenAI support ensures optimal compatibility with GPT models for tool calling and structured output

FAQ

Frequently asked questions

01

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.

02

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").

03

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.

04

How does the OpenAI Agents SDK connect to MCP?

Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.

05

Can I use multiple MCP servers in one agent?

Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.

06

Does the SDK support streaming responses?

Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.

07
