Show HN: Debugging data, not just code: Using Claude & Cursor with Kuzu MCP

Kuzu is an open source, embedded graph database that supports the Cypher query language. We wrote a blog post that serves the dual role of explaining what MCP is and how the MCP server of a database system can be useful. Our demo is based on getting Cursor (or Claude Desktop) to debug a bug in a database (and not in the code itself, which LLMs can already do without any access to the database). The biggest advantage of this way of interacting with a local embedded database like Kuzu, is that a typical 4-5 step debugging session (where the developer would write manual Cypher queries to understand the data), can now be automatically done by an LLM with a single and very simple starter prompt.

Perhaps a lot of similar data engineering/analysis tasks (e.g., ETL, quantifying results, visualization) in the future can be much more easily delegated to LLMs with simple prompts via MCP servers of database systems (possibly multiple of them at the same time). It would be fascinating to see the programming patterns that emerge in this space as MCP clients/servers evolve alongside! We'd love to get feedback and hear more about how otler folks are getting LLMs to do cool stuff using database MCP servers!
