• 01

  How does this MCP prevent AI hallucinations?

  It moves the math from the language model to a dedicated calculation engine. The AI only sees the final, computed numbers, not the raw data it has to guess at.

• 02

  Can I use this with large CSV files?

  Yes. It is specifically designed to handle massive CSVs that would exceed the context limits of standard AI clients.

• 03

  What engine is used for the calculations?

  The MCP uses Arquero, a high-performance JavaScript data engine used for professional data wrangling.

• 04

  Will this save me money on tokens?

  Yes. Because the engine processes the raw rows and only sends the small, aggregated result back to the AI, you avoid paying for millions of unnecessary tokens.

• 05

  Which AI clients can use this MCP?

  Any MCP-compatible client, including Claude, Cursor, Windsurf, and VS Code.

• 06

  What is the maximum CSV size supported?

  The engine runs locally via Node.js, meaning it can handle gigabytes of CSV data as long as your machine has sufficient RAM. There is no artificial size cap.

• 07

  Which aggregation functions are supported?

  Currently: sum, mean, count, min, and max. You can map different columns to different aggregations in a single call (e.g., sum Revenue and count Orders simultaneously).

• 08

  Why use Arquero instead of sending the CSV to the AI?

  LLMs charge per token. A large CSV can cost dollars per query and the math will be hallucinated. Arquero is free, local, and processes data with mathematically perfect deterministic precision.
