Connecting Parallax to Claude Desktop via MCP: Real-Time Factor Research Setup

Conversational Factor Research via Model Context Protocol

The Model Context Protocol (MCP) is an open standard that enables large language model applications to interact securely with external data systems and analytical tools. By integrating Parallax's MCP server with Claude Desktop, quantitative analysts and portfolio managers can perform conversational factor screening, execute risk queries, and retrieve real-time stock scores directly within their AI research workspace.

This integration bridges quantitative finance models with natural language interfaces, allowing research teams to analyze complex portfolio exposures without context switching between standalone tools.

Setup Instructions for Claude Desktop

Connecting Claude Desktop to Parallax requires adding the remote MCP endpoint to your local configuration file.

Step 1: Open the Claude Desktop Configuration File

Locate the claude_desktop_config.json configuration file on your operating system:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Step 2: Add the Parallax MCP Configuration Block

Add the parallax server definition using mcp-remote to connect to the verified Parallax endpoint at mcp.chicago.global:

{
  "mcpServers": {
    "parallax": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.chicago.global/api/mcp"]
    }
  }
}

Step 3: Complete Authentication and Restart

Restart Claude Desktop. On first launch, a browser window opens automatically to complete OAuth authentication with your Parallax account and authorize analytical tool access.

Executing Conversational Factor Queries

Once configured, Claude Desktop has direct access to Parallax's scoring engine. Analysts can submit conversational research prompts such as:

• "Screen for US equities in the top quartile of Quality and Defensive scores with low leverage."
• "Decompose the factor profile of Microsoft and Apple across Value, Quality, Momentum, and Size."
• "Evaluate the risk implications of rotating 5% of portfolio weight from momentum winners into defensive dividend payers."
