What is the DataFrame Aggregator Engine MCP Server?
If you feed a 1,000,000-row CSV to an LLM and ask it to 'group by Region and sum the Revenue', the AI will either crash due to context limits or hallucinate the result.
This MCP delegates heavy data wrangling to arquero, an industry-standard high-performance JS data engine. The AI orchestrates the query, passes the raw CSV, and the engine computes exact sums, means, and counts instantly.
The Superpowers
- Massive Token Savings: The AI only reads the aggregated output, not the millions of raw rows.
- Zero Hallucination: Deterministic math performed by your CPU — not estimated by a language model.
- Blazing Fast: Powered by Arquero, the gold-standard JS data wrangling library used in academic visualization research.
- Multi-Aggregation: Apply different aggregation types to different columns in a single call.
Built-in capabilities (1)
Perform extremely fast, deterministic GroupBy, Pivot, and Aggregations on massive CSV strings offline
Why Claude Code?
Claude Code registers DataFrame Aggregator Engine as an MCP server in a single terminal command. Once connected, Claude Code discovers all 1 tools at runtime and can call them headlessly. ideal for CI/CD pipelines, cron jobs, and automated workflows where DataFrame Aggregator Engine data drives decisions without human intervention.
- —
Single-command setup:
claude mcp addregisters the server instantly. no config files to edit or applications to restart - —
Terminal-native workflow means MCP tools integrate seamlessly into shell scripts, CI/CD pipelines, and automated DevOps tasks
- —
Claude Code runs headlessly, enabling unattended batch processing using DataFrame Aggregator Engine tools in cron jobs or deployment scripts
- —
Built by the same team that created the MCP protocol, ensuring first-class compatibility and the fastest adoption of new protocol features

Frequently asked questions
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.
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).
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.
How do I add an MCP server to Claude Code?
Run claude mcp add <name> --transport http "<url>" in your terminal. Claude Code registers the server and discovers all tools immediately.
Can Claude Code run MCP tools in headless mode?
Yes. Claude Code supports non-interactive execution, making it ideal for scripts, cron jobs, and CI/CD pipelines that need MCP tool access.
How do I list all connected MCP servers?
Run claude mcp in your terminal to see all registered servers and their status, or type /mcp inside an active Claude Code session.
