Qrnl

Compiled tools for AI agents

Agents write the query.
Qrnl turns it into a tool.

Qrnl compiles a SQL, pandas or PySpark query into a small native program specialised to exactly that query — millisecond start, tiny footprint, no engine underneath. Built for the thousands of small, recurring queries agents fire every day, called with new parameters each time.

What it does

  • faster than DuckDB and faster than pandas on TPC-H

    SF=10 · 1 core · 22/22 queries correct

  • Cold start in milliseconds — the binary is the query

  • Every compiled query becomes an MCP tool — local server, pip install.
