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.

See how to talk to your AI agent using 4D.

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

I've retrieved the first 5 invoices from your 4D database. Here are the details including IDs, amounts, and dates.

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

I've explored your 4D catalog. You have the following DataClasses available: Invoices, Customers, Products, and Orders. Which one would you like to query?

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

I've successfully created the new customer record for John Doe in your 4D database. The record is now live and assigned a new primary key.

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