How to Use the 4D MCP in Claude Code

Q: How do I register the 4D MCP Server in Claude Code?

Run claude mcp add --transport http 4d-mcp -- in your terminal. This command updates your local file with the MCP configuration. Run claude mcp list to verify the connection is active.

Q: Can I use Claude Code to script 4D database migrations?

Yes, Claude Code uses createentity and updateentity to modify records programmatically. You can build terminal scripts that pipe JSON data directly into your tables, making data migrations simple.

Q: How does Claude Code handle 4D database lookups?

The CLI tool uses listentities to search tables using ORDA-style filters. It prints the results directly to your terminal, allowing you to filter and sort datasets on the fly.

Q: Does the terminal tool support schema discovery?

Claude Code calls getcatalog to fetch your database definitions. This lets the command-line agent verify table layouts and field structures before executing any data operations.

Run headless 4D database operations directly from your terminal using Claude Code.

Query 4D databases via the Claude Code CLI

`list_entities` queries your database tables using terminal commands. This tool lets you run ORDA-style lookups with filters and ordering without leaving your shell. You can pipe this output directly into other CLI tools or scripts. It makes automation easy for SREs and backend developers who manage data pipelines.

Inspect 4D database catalogs from your terminal

`get_catalog` pulls your entire database structure into your terminal session. This tool helps you quickly check table definitions and field types during shell tasks. You don't need a heavy GUI to inspect your database anymore. Run a quick terminal command to let Claude Code map out the schema for your scripts.

Manage 4D table records using this MCP Server

`create_entity` and `update_entity` modify your database records directly from the command line. These tools accept JSON payloads to write or update entities instantly. You can automate database seeding or quick updates inside your CI/CD pipelines. Claude Code formats the payloads and executes the operations in headless environments.
