Raindrop + Gemini CLI Quick Start

The Raindrop MCP server transforms Gemini CLI 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 Gemini CLI

Follow the installation instructions at Gemini CLI GitHub repository.

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-gemini

What this command does:

• Configures Gemini CLI with the correct MCP server URL
• Sets up RAINDROP.md guidelines in ~/.gemini/
• Creates custom TOML slash commands in ~/.gemini/commands/:
  • /new-raindrop-app
  • /update-raindrop-app
  • /reattach-raindrop-session

Step 5: Start Gemini CLI

1. Start or restart Gemini CLI for changes to take effect

gemini

2. Authenticate and connect raindrop-mcp with gemini

/mcp auth raindrop-mcp

3. Verify the MCP server is available:

/mcp list

Note

You should see raindrop-mcp in the list of available servers

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 Slash Command:

/new-raindrop-app

Using Direct MCP Call:

Use the raindrop-mcp login 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
