Northern Trust MCP Layer - Prototype

This repository implements a "Server of Servers" architecture using the Model Context Protocol (MCP). It features a central Orchestrator that aggregates domain-specific data capabilities (like Performance) into a single, governed interface.

Repository Structure

orchestrator/: The main gateway server. Handles routing and tool aggregation.
domains/performance/: Sample domain implementation providing fund performance tools.
package.json: Root configuration for managing the workspace.

Prerequisites

Node.js (v18+)
NPM

Setup Instructions

Install Dependencies Run from the root directory:
```
npm install
```
Build the Projects
```
npm run build:all
```
Run for Testing

Option A: Test individual domains
```
cd domains/performance
npm run dev
```
Option B: Test the Orchestrator (Server of Servers)
```
cd orchestrator
npm run dev
```

Key Features

Namespace Routing: Tools from the Performance domain are automatically prefixed with perf_ by the orchestrator.
Dynamic Discovery: The orchestrator fetches the tool manifest from domain servers on startup.
Type Safety: Built with TypeScript and Zod for robust schema validation.
Standard Protocol: Compatible with any MCP-compliant client (e.g., Gemini, Claude Desktop).

Available Tools (via Orchestrator)

perf_get_fund_returns: Returns YTD and 1-year performance.
perf_benchmark_comparison: Compares fund vs benchmark.
perf_sharpe_ratio: Returns risk-adjusted performance metric.
