Data Aggregator MCP Server

What this does

Data Aggregator exposes a set of tools to Claude over the Model Context Protocol. After you add it to claude_desktop_config.json (snippet above) and restart Claude Desktop, those tools become callable inside any conversation.

This server needs the following environment variables to be set before it can run:

NCBI_API_KEY

LLM_MODEL
EMBEDDING_API_BASE
EMBEDDING_API_KEY
EMBEDDING_MODEL

Set these via the env object in your MCP config (see claude_desktop_config.json snippet above).
