Sharesight MCP Server

A Model Context Protocol (MCP) server that provides AI assistants with access to the Sharesight portfolio tracking platform via the v3 API.

Quick Start

Step 1: Get OAuth Credentials

You'll need a Client ID and Client Secret from Sharesight to use this server.

How to get credentials:

• Contact Sharesight support at support@sharesight.com to request API access
• Visit the Sharesight API documentation for more information
• API access may require a specific Sharesight plan

Step 2: Run One-Time Authentication

npx github:Haizzz/sharesight-mcp auth

The CLI will:

1. Prompt for your Client ID and Client Secret
2. Display a URL to open in your browser
3. Ask you to log in to Sharesight and authorize the app
4. Prompt you to paste the authorization code
5. Save tokens locally (they refresh automatically)

Step 3: Add MCP Server Configuration

Add to your Claude Desktop config file:

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

{
  "mcpServers": {
    "sharesight": {
      "command": "npx",
      "args": ["-y", "github:Haizzz/sharesight-mcp", "serve"],
      "env": {
        "SHARESIGHT_CLIENT_ID": "your_client_id",
        "SHARESIGHT_CLIENT_SECRET": "your_client_secret"
      }
    }
  }
}

Restart Claude Desktop and you're ready to go!
