Knowledge Graph RDBMS MCP Server

Knowledge Graph RDBMS is an MCP integration. A label property graph on SQLite/Postgres with multi-ontology routing and a gated MCP server.

Packages and local setup

The published pypi package is knowledge-graph-rdbms, version 0.1.9. Its declared MCP transport is stdio.

The package declares KGRDBMS_HOME: Storage root for ontology databases and the event log. Defaults to ~/.kgrdbms.; KGRDBMS_DEFAULT_ONTOLOGY: Name of the default ontology used when a tool call omits the ontology argument. Defaults to "default"..

This package has launch arguments in its registry record. Use the maintainer’s configuration for those arguments rather than launching it with only the package name.

Before connecting

Check the maintainer’s instructions for account access, authentication and the supported client configuration. Once connected, inspect the tools your client receives and try a small task that matches the server’s stated purpose. The registry description does not include a verified, complete tool list.
