MCP Server for Data Engineering Knowledge
MCP Server for Data Engineering Knowledge
This repo contains a simple Model Context Protocol (MCP) server built with Node.js and TypeScript. It acts as a "Data Engineering Tutor," providing personalized updates about Data Engineering concepts, patterns, and technologies to a connected AI client.
npm (or your preferred Node.js package manager like yarn or pnpm) - An AI client capable of connecting to an MCP server (e.g., Cursor, Claude desktop app) - An OpenRouter API Key (for fetching live Data Engineering updates via Perplexity)de_tutor_read_memory — Reads the current known concepts from the JSON file.de_tutor_write_memory — Updates the JSON file to mark a concept as known (true) or unknown (false). Takes concept (string) and known (boolean) as input.de_tutor_get_updates — Uses your OpenRouter API key to query Perplexity (perplexity/sonar-small-online) for recent Data Engineering news, patterns, and technologies.Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
| Tool | What it does |
|---|---|
| de_tutor_read_memory | Reads the current known concepts from the JSON file. |
| de_tutor_write_memory | Updates the JSON file to mark a concept as known (true) or unknown (false). Takes concept (string) and known (boolean) as input. |
| de_tutor_get_updates | Uses your OpenRouter API key to query Perplexity (perplexity/sonar-small-online) for recent Data Engineering news, patterns, and technologies. |
