Knowledge Graph RDBMS

Overview

Knowledge Graph RDBMS is an MCP server that implements a label property graph on SQLite or Postgres, with multi-ontology routing and gated access. It exposes graph operations as tools that AI assistants can invoke directly, letting you query and traverse knowledge structures through your MCP client.

The server runs locally on your machine via the knowledge-graph-rdbms Python package, installed with uvx knowledge-graph-rdbms. It communicates over stdio and requires no authentication to get started. Version v0.1.9 is available under the MIT license, with source code at cunicopia-dev/knowledge-graph-rdbms on GitHub.

Knowledge Graph RDBMS belongs in the Database category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and any standards-compliant MCP client. If you maintain this server, claim your listing to earn the Verified badge and keep the information up to date.
