Uses Brave Search API to perform web searches for gathering information during the research process
Serves as an open-source alternative to Perplexity Deep Research, providing similar research capabilities
OpenDeepSearch
An open-source alternative to Perplexity Deep Research using the Model Context Protocol (MCP).
Overview
OpenDeepSearch is a powerful research tool that performs comprehensive, in-depth research on complex topics. It combines the structured thinking approach of Sequential Thinking with the search capabilities of Brave Search to provide detailed, well-sourced research reports.
Features
Comprehensive Research: Breaks down complex questions into manageable sub-questions
Iterative Search: Performs multiple searches to gather diverse information
Intelligent Analysis: Analyzes search results to extract relevant information
Synthesis: Combines findings into a coherent, well-structured report
Citations: Includes sources for all information in the report
MCP Integration: Seamlessly integrates with Claude Desktop, Cursor, and other MCP clients
WebSockets: Supports integration with Smithery and other MCP clients
Publication: Allows publishing the research tool on the Smithery platform for easy access
Installation
Prerequisites
Node.js 16 or higher
A Brave Search API key (get one at https://brave.com/search/api/)
NPM Installation
npm install -g open-deep-research
Running with NPX
BRAVE_API_KEY=your_api_key npx open-deep-research
Local Installation
# Clone the repository
git clone https://github.com/tositon/open-deep-research.git
cd open-deep-research
# Install dependencies
npm install
# Build the project
npm run build
# Run with Brave Search API
BRAVE_API_KEY=your_api_key npm start
Installation via Smithery
# Install for Claude
npx @smithery/cli install open-deep-research --client claude
# Install for Cursor
npx @smithery/cli install open-deep-research --client cursor
When installing via Smithery, you will be prompted to enter a Brave Search API key.
Usage
With Claude Desktop
Add the following to your Claude Desktop configuration:
{
"mcpServers": {
"open-deep-research": {
"command": "npx",
"args": [
"-y",
"open-deep-research"
],
"env": {
"BRAVE_API_KEY": "your_api_key_here"
}
}
}
}
With Cursor
In Cursor, you can add the MCP server with:
claude mcp add "open-deep-research" npx open-deep-research
Make sure to set the BRAVE_API_KEY environment variable before running Cursor.
Example Queries
"What are the latest developments in quantum computing?"
"Compare and contrast different approaches to climate change mitigation"
"Explain the history and impact of the Renaissance on European art"
"What are the pros and cons of different renewable energy sources?"
How It Works
Question Analysis: The system analyzes the main question and breaks it down into sub-questions
Iterative Search: For each sub-question, the system performs searches using Brave Search API
Result Analysis: The system analyzes the search results to extract relevant information
Synthesis: The system combines the findings into a coherent report
Citation: All information is properly cited with sources
Development
Setup
git clone https://github.com/tositon/open-deep-research.git
cd open-deep-research
npm install
Build
npm run build
Run in Development Mode
BRAVE_API_KEY=your_api_key npm run dev
Testing
Testing with MCP Inspector
Для тестирования MCP сервера можно использовать MCP Inspector, который предоставляет удобный интерфейс для взаимодействия с инструментами:
# Установка и запуск MCP Inspector
npx @modelcontextprotocol/inspector
# Запуск сервера в другом терминале
BRAVE_API_KEY=your_api_key npm start
После запуска Inspector, откройте браузер и перейдите по адресу http://localhost:5173. Подключитесь к WebSocket серверу, используя URL ws://localhost:3000.
Примеры запросов для тестирования инструментов
В интерфейсе MCP Inspector вы можете выбрать инструмент и настроить параметры запроса:
Тестирование Brave Web Search
{
"query": "latest quantum computing advancements",
"count": 5
}
Тестирование Sequential Thinking
{
"thought": "Начинаю анализ проблемы глобального потепления",
"thoughtNumber": 1,
"totalThoughts": 5,
"nextThoughtNeeded": true
}
Тестирование Deep Research
{
"query": "Сравнение различных источников возобновляемой энергии",
"action": "start",
"maxSubQuestions": 3
}
Testing with Claude or Cursor
После установки сервера через Smithery или локально, вы можете использовать его с Claude Desktop или Cursor, выбрав соответствующий MCP сервер в настройках.
Publishing on Smithery
To publish the server on the Smithery platform:
Ensure the repository is hosted on GitHub and is public
Register on the Smithery platform
Authenticate via GitHub to connect with the repository
Go to the "Deployments" tab on the server page
Click the "Deploy on Smithery" button
Follow the deployment setup instructions
After publishing, users can install the server using the Smithery CLI:
npx @smithery/cli install open-deep-research --client claude
