Under Validation

Query Gigabytes of Local CSVs & Parquet with SQL inside Claude Code.

Give your AI developer agents the blazing-fast DuckDB engine. Let them run on-device SQL to filter, join, and analyze local files without hitting context limits.

Proposed workflow

Smart caching, kept entirely local.

We believe that data analysis shouldn't sacrifice privacy or run up expensive cloud API token bills.

01

On-Device DuckDB Analytics

Auto-detects local files, infers schemas, and executes analytical SQL queries locally in milliseconds without database configuration.

02

Slash LLM API Token Costs

Query, filter, and aggregate million-row logs on localhost and send only the concise, structured query result back to your agent.

03

100% Private & Offline

Runs entirely as a local daemon. Your proprietary datasets, log files, and database dumps never touch any external network.

The honest status

This is a product decision, not a finished product.

The concept is being validated before development time is committed. Joining tells us the problem is relevant to you and gives you first access if the evidence supports a build.

Before you decide

Questions, answered clearly.

The current scope, privacy model, and next step without launch-day promises.

How do I install the MCP DuckDB Query server?

It runs as a lightweight on-device daemon. Once installed via npm or homebrew, you add its configuration to your Claude Desktop or Cursor settings file in under a minute.

Which file formats does it support?

It supports CSV, Parquet, JSON-Lines (NDJSON), TSV, and Excel spreadsheets using DuckDB's fast auto-detecting file scanner.

Does this guarantee the intended outcome?

No. The concept should state its limits clearly and preserve human review wherever judgment is required.

What happens when I request access?

Your email is recorded for this experiment only. You receive one relevant update or beta invitation if the concept moves forward.
