Full 4D database control in Claude Desktop

You can now read and modify your production data without leaving the chat interface. Use `get_entity` or `list_entities` to pull specific records into your context window instantly. Updating your database state is just as simple. Send a JSON payload through `update_entity` to push changes back to your 4D backend without context switching.

Explore schema via Claude Desktop

Stop digging through documentation to find table names or field types. Point this MCP Server at your instance and run `get_catalog` to see the entire structure. Your agent parses this metadata to build accurate queries. It knows exactly what fields exist before it tries to write data.

Automated 4D record lifecycle

Need to clean up stale data or spin up test entries? Call `create_entity` or `delete_entity` to perform administrative tasks through natural language prompts. These tools talk directly to your database over standard REST. You get the speed of an API with the conversational flow of your AI client.
