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

Create your Raindrop account:

Sign up for a Raindrop account at liquidmetal.run
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

Start or restart Gemini CLI for changes to take effect

gemini

Authenticate and connect raindrop-mcp with gemini

/mcp auth raindrop-mcp

Verify the MCP server is available:

/mcp list

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
