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
- Subscribe to this server
- Enter your 4D Server Base URL and Credentials
- 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.

Frequently asked questions
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.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
