Open Deep Research MCP Server

An AI-powered research assistant that performs deep, iterative research on any topic. It combines search engines, web scraping, and AI to explore topics in depth and generate comprehensive reports. Available as a Model Context Protocol (MCP) tool or standalone CLI. Look at exampleout.md to see what a report might look like.

Quick Start

1. Clone and install:

git clone https://github.com/Ozamatash/deep-research
cd deep-research
npm install

2. Set up environment in .env.local:

# Copy the example environment file
cp .env.example .env.local

3. Build:

# Build the server
npm run build

4. Run the cli version:

npm run start

5. Test MCP Server with Claude Desktop:
   Follow the guide thats at the bottom of server quickstart to add the server to Claude Desktop:
   https://modelcontextprotocol.io/quickstart/server

For remote servers: Streamable HTTP

npm run start:http

Server runs on http://localhost:3000/mcp without session management.

Features

• Performs deep, iterative research by generating targeted search queries
• Controls research scope with depth (how deep) and breadth (how wide) parameters
• Evaluates source reliability with detailed scoring (0-1) and reasoning
• Prioritizes high-reliability sources (≥0.7) and verifies less reliable information
• Generates follow-up questions to better understand research needs
• Produces detailed markdown reports with findings, sources, and reliability assessments
• Available as a Model Context Protocol (MCP) tool for AI agents
• For now MCP version doesn't ask follow up questions
• Natural-language source preferences (avoid listicles, forums, affiliate reviews, specific domains)

Model Selection (OpenAI, Anthropic, Google, xAI)

Pick a provider and model per run.

• CLI: you will be prompted for provider and model. Example: openai + gpt-5.2.
• MCP/HTTP: pass model, e.g. openai:gpt-5.2 (also accepts openai/gpt-5.2).

Set the corresponding API key in .env.local:

OPENAI_API_KEY=...
ANTHROPIC_API_KEY=...
GOOGLE_API_KEY=...
XAI_API_KEY=...

Optionally set default models per provider:

OPENAI_MODEL=gpt-5.2
ANTHROPIC_MODEL=claude-opus-4-5
GOOGLE_MODEL=gemini-3-pro-preview
XAI_MODEL=grok-4-1-fast-reasoning

If you use a non-default OpenAI endpoint:

OPENAI_ENDPOINT=https://api.openai.com/v1

Advanced Setup

Using Local Firecrawl (Free Option)

Instead of using the Firecrawl API, you can run a local instance. You can use the official repo or my fork which uses searXNG as the search backend to avoid using a searchapi key:

1. Set up local Firecrawl:

git clone https://github.com/Ozamatash/localfirecrawl
cd localfirecrawl
# Follow setup in localfirecrawl README

2. Update .env.local:

FIRECRAWL_BASE_URL="http://localhost:3002"

Optional: Observability

Add observability to track research flows, queries, and results using Langfuse:

# Add to .env.local
LANGFUSE_PUBLIC_KEY="your_langfuse_public_key"
LANGFUSE_SECRET_KEY="your_langfuse_secret_key"

The app works normally without observability if no Langfuse keys are provided.
