How to Use the DataFrame Aggregator Engine MCP in Claude Code

Q: Where is the configuration stored?

The CLI saves your server settings in /.claude.json. You can inspect or modify this file directly if you need to adjust connection parameters.

Run deterministic CSV aggregations directly from your terminal using Claude Code and this specialized MCP Server.

Perplexity

Headless CSV processing

Terminal users need fast answers from log files and data dumps without opening a Jupyter notebook. You can pipe a raw CSV into Claude Code and let it handle the parsing. The CLI agent calls the `aggregate_dataframe` tool to group and sum the data behind the scenes. You get the exact summary printed to stdout, ready to pipe into jq or another shell utility.

Slash token usage in CI/CD

Automated jobs that analyze test results or performance metrics generate huge CSV outputs. Feeding those directly to an LLM inside a GitHub Action is incredibly expensive. This MCP server intercepts that heavy lifting. The agent offloads the math to the local tool, reading only the condensed pivot table. Your automated pipelines run faster and cost significantly less.

Exact arithmetic for Claude Code

Command-line agents are great at writing bash scripts but terrible at calculating averages across ten thousand rows. Probabilistic models guess numbers. By exposing a deterministic engine via MCP, your terminal agent gets a calculator designed for massive datasets. You can trust the financial totals or error counts it spits out.

Setup guide

Set up DataFrame Aggregator Engine MCP in Claude Code

Prerequisites

Claude Code CLI installed (npm install -g @anthropic-ai/claude-code)
Active Vinkius subscription with a valid endpoint token

1

Run the add command

Open your terminal and run the command shown on the right. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com. Use --scope user to make it available across all projects.
2

Verify the connection

Start a Claude Code session and type /mcp to list connected servers. You should see dataframe-aggregator-engine-mcp with a green status indicator.
3

Start using tools

Ask Claude Code something like "Check my latest DataFrame Aggregator Engine transactions." It will automatically discover and invoke the available DataFrame Aggregator Engine tools.

Terminal

claude mcp add --transport http dataframe-aggregator-engine-mcp https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp

Prerequisites

Claude Code CLI installed
Active Vinkius subscription with a valid endpoint token

1

Open the config file

Create or edit .mcp.json in your project root for project-level scope, or ~/.claude.json for user-level scope.
2

Add the DataFrame Aggregator Engine MCP

Paste the JSON snippet shown on the right into the mcpServers object. Replace [YOUR_TOKEN_HERE] with your endpoint token from cloud.vinkius.com.
3

Restart Claude Code

Start a new Claude Code session. Type /mcp to confirm the server is connected. The tools will be automatically available in your conversation.

Common questions about DataFrame Aggregator Engine MCP in Claude Code

Run claude mcp add --transport http -- in your terminal. Make sure all flags come before the server name. Use claude mcp list to verify the connection.

Yes. Since the CLI operates headlessly, you can configure the server in your CI environment. The agent will process CSV artifacts automatically during the build step.

While awk and sed are powerful, writing complex pivot tables in bash is painful. This tool gives the agent a single, instant operation to perform advanced GroupBy logic without writing new scripts.

The CLI saves your server settings in ~/.claude.json. You can inspect or modify this file directly if you need to adjust connection parameters.

Vinkius processes your CSV strings in an isolated V8 sandbox. The numeric data and text rows are held in memory just long enough to compute the aggregation, then completely wiped.
