# Overview

> Noonum helps transform your thought/idea into an investment solution in a matter of minutes. Build, back-test, and manage them with the Noonum REST API and MCP server.

Noonum is a thematic investment platform that allows you to describe your investment objective in plain English to generate a basket of holdings, score and weight them by thematic strength, build an optimized portfolio, and back-test the result. You do this through a public REST API and an MCP server for AI agents. [MCP (Model Context Protocol)](/base/agentic/overview) is an open standard that lets AI agents call external tools; the Noonum MCP server exposes Noonum's analytics as such tools.

## The workflow

Authenticate, then reuse or build a strategy. Review the holdings and their reasoning and refine until the companies are right. Optimize to a weighted portfolio and back-test it against a benchmark.

Every request is authenticated with an `Authorization: Bearer <token>` header, where the token is your Noonum API key. See [Authentication](/v2/getting-started/authentication) for details.
