Connecting Sandcastles to Claude

This guide will walk you through setting up the Sandcastles MCP within Claude, allowing you to leverage Sandcastles' data analysis capabilities directly in your AI interactions.

Below the instructions, you will find videos for the specific social media skills that come in the plugin and our favorite workflows (e.g., how to build an automated topic leaderboard tracker for your niche)

INSTRUCTIONS

Step 1: Accessing Sandcastles MCP Plugin

  1. Navigate to the Settings section in the left-hand sidebar of your Sandcastles interface.
  2. Click on Connectors.
  3. You will see an API section and an MCP section. For this setup, we will focus on the MCP section.
  4. Go to the MCP Section and click “Download Plugin vX.X.X”

Note: you must be a Pro, Visionary or Titan user to access the MCP. If you’re on the Starter plan, upgrade via Settings → Subscription

Step 2: Installing the Sandcastles Plugin in Claude

  1. Download the Claude Desktop App (https://claude.com/download) (must be in the Desktop app to install the plugin, can’t do it from the normal browser-based chat)
  2. In the Claude Desktop app, click “Customize” → Click “Plugins” (bottom left side nav) → Click “Add” (upper right) → click “Upload Plugin”
  3. Drag the Sandcastles Plugin Zip Folder into the area and press “Upload”
  4. Once it’s loaded in, press “Connectors” (in the middle of the page, still within the Plugins menu. Do not click Connectors in the bottom left nav yet. Click the Install button next to it.
  5. A modal window titled "Add custom connector" will appear. The fields for "sandcastles" and the URL https://mcp.sandcastles.ai/ should be pre-filled.
  6. You can expand Advanced settings if needed, but for a standard setup, these are optional and not needed. Don’t type anything here.
  7. Click the Add button.

Note: The process of adding the connector via the "Add custom connector" modal may seem to do nothing on the screen, but the connector is being registered in the background. If you try to re-add it, you’ll get a pop-up notification that you have already added it.
