Raindrop + Claude Quick Start

The Raindrop MCP server transforms Claude Code into a powerful infrastructure development platform. Instead of just writing code, you can build complete applications with databases, APIs, and deployment infrastructure through structured, guided workflows.

Step 1: Install Required Tools

Install Claude Code

npm install -g @anthropic-ai/claude-code

Install Raindrop CLI

npm install -g @liquidmetal-ai/raindrop

Step 2: Sign Up for Raindrop

Create your Raindrop account:

1. Sign up for a Raindrop account at liquidmetal.run
2. Complete the account setup process

Step 3: Authenticate

Run the following command to authenticate the Raindrop CLI:

raindrop auth login

Step 4: Set Up MCP Integration

Run the following command in your terminal to set up the MCP integration:

raindrop mcp install-claude

What this command does:

• Configures Claude Code with the correct MCP server URL
• Sets up raindrop.md and custom slash commands for Claude Code (/new-raindrop-app, /update-raindrop-app, and /reattach-raindrop-session)

Step 5: Start Claude Code

1. Start Claude Code
2. Run /mcp
3. Select the raindrop-mcp server
4. Select Authenticate
5. Login to your Raindrop account (or click Allow Access if you are already logged in)

Using the Raindrop MCP Server

Once configured, you have access to three main workflows for building applications:

1. Start a New Application

Create a new Raindrop application from scratch:

Using Shorthand Command:

/new-raindrop-app

Using Direct MCP Call:

Claude, call the LiquidMetal Raindrop:login MCP tool to start a new application development session.

What Happens:

• Creates a new session ID and timeline ID
• Guides you through requirements gathering (PRD creation)
• Generates application architecture and manifest
• Sets up databases, services, and infrastructure
• Implements complete application code
• Deploys to live infrastructure
• Validates deployment with endpoint testing

2. Reattach to an Existing Session

Resume work on a previous application:

Using Shorthand Command:

/reattach-raindrop-session [session_id] [timeline_id]

Using Direct MCP Call:

Claude, call the LiquidMetal Raindrop:reattach_to_session MCP tool with session_id "your-session-id" and timeline_id "your-timeline-id".

Finding Your Session IDs: You can instruct Claude Code to look in your .raindrop.config.local.json file to find your session and timeline IDs.

What Happens:

• Restores complete project context and progress
• Shows current development phase and next steps
• Continues from exactly where you left off
• Maintains all architectural decisions and requirements

3. Update an Existing Application

Add features or modify a deployed application:

Using Shorthand Command:

/update-raindrop-app [session_id] [old_timeline_id]

Using Direct MCP Call:

Claude, call the LiquidMetal Raindrop:update_app_step MCP tool with session_id "your-session-id" and old_timeline_id "your-timeline-id".

Finding Your Session IDs: You can instruct Claude Code to look in your .raindrop.config.local.json file to find your session and timeline IDs.

What Happens:

• Creates a new timeline for the update--- title: Raindrop + Claude Quick Start description: Get started with the Raindrop MCP server for Claude Code to build and deploy complete applications through guided workflows.
