Raindrop.io MCP server for AI agents

The Raindrop.io MCP Server is a tool that enables Large Language Models (LLMs) to interact with your Raindrop.io bookmarks using the Model Context Protocol. With this integration, you can create new bookmarks and search through your existing collections directly from compatible LLM applications.

Requirements

Go 1.20 or higher
Raindrop.io account and API token

Installation

1. Clone the Repository

git clone https://github.com/anarcher/raindrop-io-mcp-server
cd raindrop-io-mcp-server

2. Install Dependencies

go mod tidy

3. Configure Your Environment

Create a .env file in the project root directory and add your Raindrop.io API token:

RAINDROP_TOKEN=your_access_token_here

4. Build the Server

go build -o raindrop-mcp-server

Setting Up with Claude for Desktop

1. Locate Claude's Configuration File

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

2. Add the MCP Server Configuration

Edit the configuration file and add the following:

{
  "mcpServers": {
    "raindrop": {
      "command": "/path/to/raindrop-mcp-server",
      "env": {
        "RAINDROP_TOKEN": "your_access_token_here"
      }
    }
  }
}

Make sure to replace /path/to/raindrop-mcp-server with the actual path to the executable you built.

3. Restart Claude

Restart the Claude for Desktop application to apply the changes.

Using the Tools

Once configured, you can use the following tools through your LLM interface:

Creating Bookmarks

The create-bookmark tool allows you to save new bookmarks to your Raindrop.io account.

Parameters:

url: URL to bookmark (required)
title: Title for the bookmark (optional)
tags: Array of tags (optional)
collection: Collection ID (optional)

Example prompt: "Save this article about climate change to my Raindrop bookmarks: https://example.com/article"

Searching Bookmarks

The search-bookmarks tool helps you find bookmarks in your collection.

Parameters:

query: Search query (required)
tags: Array of tags to filter by (optional)

Example prompt: "Find all my bookmarks related to machine learning" or "Show me bookmarks tagged with 'recipe' and 'vegetarian'"

Security Best Practices

Store your API token in environment variables rather than hardcoding it
Set appropriate permissions for the Claude configuration files
Regularly review and update your API tokens

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "raindrop" '{"command":"/path/to/raindrop-mcp-server","env":{"RAINDROP_TOKEN":"your_access_token_here"}}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "raindrop": {
            "command": "/path/to/raindrop-mcp-server",
            "env": {
                "RAINDROP_TOKEN": "your_access_token_here"
            }
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

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

2. Add this to your configuration file:

{
    "mcpServers": {
        "raindrop": {
            "command": "/path/to/raindrop-mcp-server",
            "env": {
                "RAINDROP_TOKEN": "your_access_token_here"
            }
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
