Excel Analyser MCP Server

A Node.js tool to read and analyse Excel (.xlsx), CSV (.csv), and JSON (.json) files using MCP with automatic pagination support.

What it actually does

A Node.js MCP server for reading and analyzing Excel (.xlsx), CSV (.csv), and JSON (.json) files. Supports multiple transport protocols (stdio, HTTP, SSE) and designed for scalable, chunked, and column/field-specific data access, making it ideal for AI agents and automation workflows that need to process large datasets efficiently.

• Multi-Transport Support — Choose between stdio (npm), HTTP streamable, or SSE transports
• Read Excel/CSV/JSON files — and output all or selected columns/fields as JSON
• Efficient Streaming — Handle multi-gigabyte JSON files with constant, low memory usage
• Powerful JSON Querying — Quickly search and filter large JSON files without loading the entire file into memory
• Chunked Access — Process large files iteratively by fetching data in configurable chunks
• Column/Field filtering — Extract only the columns or fields you need

Configuration

• Node.js (v18 or higher recommended)
