MCP Server: Ollama Deep Researcher

This is a Model Context Protocol (MCP) server adaptation of LangChain Ollama Deep Researcher. It provides the deep research capabilities as MCP tools that can be used within the model context protocol ecosystem, allowing AI assistants to perform in-depth research on topics using local LLMs via Ollama.

Core Functionality

The server provides research capabilities through MCP tools and resources, using any LLM hosted by Ollama.

Research Process

Given a topic, it will:

  1. Generate a web search query

  2. Gather web search results via Tavily or Perplexity API

  3. Summarize the search results

  4. Reflect on the summary to examine knowledge gaps

  5. Generate new search queries to address the gaps

  6. Iteratively improve the summary through multiple research cycles

  7. Provide a final markdown summary with all sources used

Prerequisites

  • Node.js (for running the MCP server)

  • Python 3.10 or higher

  • Compute (CPU/GPU) capable of running your selected Ollama model

  • At least 8GB of RAM for running larger language models

  • Required API keys:

Make sure you can run Node.js and npm from your terminal/command prompt. You can verify your installations with:

node --version npm --version python --version

If these commands fail, you may need to:

  1. Restart your terminal/computer after installation

  2. Add Node.js to your system PATH:

    • Windows: Edit system environment variables → Environment Variables → Path → Add Node.js installation directory

    • macOS/Linux: Usually handled by the installer

Installation

Option 1: Standard Installation

  1. Download and install Ollama for your platform

  2. Clone this repository and install dependencies:

git clone https://github.com/Cam10001110101/mcp-server-ollama-deep-researcher cd mcp-server-ollama-deep-researcher npm install

  1. Install Python dependencies:

First, install uv (recommended for better performance and dependency resolution):

# Windows pip install uv # macOS/Linux pip3 install uv

Then install project dependencies using pyproject.toml:

uv pip install .

Note: This will install the project in editable mode with all dependencies specified in pyproject.toml. If you prefer pip:

pip install . # Windows pip3 install . # macOS/Linux

  1. Build the TypeScript code:

npm run build

  1. Pull a local LLM from Ollama:

ollama pull deepseek-r1:8b

Option 2: Docker Installation

You can also run the MCP server using Docker, which simplifies the setup process.

  1. Download and install Docker for your platform

  2. Clone this repository:

git clone https://github.com/Cam10001110101/mcp-server-ollama-deep-researcher cd mcp-server-ollama-deep-researcher

  1. Create a .env file with your API keys (you can copy from .env.example):

cp .env.example .env # Edit the .env file with your API keys

  1. Make the helper script executable:

chmod +x run-docker.sh

  1. Build and run the Docker container:

./run-docker.sh start

  1. Ensure Ollama is running on your host machine:

ollama pull deepseek-r1:8b # or your preferred model ollama serve

The helper scripts provide several commands:

For macOS/Linux (using run-docker.sh):

  • ./run-docker.sh start - Build and start the Docker container

  • ./run-docker.sh stop - Stop the Docker container

  • ./run-docker.sh restart - Restart the Docker container

  • ./run-docker.sh logs - Show logs from the Docker container

  • ./run-docker.sh status - Check the status of the Docker container

  • ./run-docker.sh help - Show help message

For Windows (using run-docker.bat):

  • run-docker.bat start - Build and start the Docker container

  • run-docker.bat stop - Stop the Docker container

  • run-docker.bat restart - Restart the Docker container

  • run-docker.bat logs - Show logs from the Docker container

  • run-docker.bat status - Check the status of the Docker container

  • run-docker.bat help - Show help message

Note: The Docker container is configured to connect to Ollama running on your host machine. If you want to run Ollama in a container as well, uncomment the Ollama service in the docker-compose.yml file.

Client Configuration

Add the server to your MCP client configuration:

For Claude Desktop App:

  • macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

  • Windows: %APPDATA%\Claude\claude_desktop_config.json

For Cline (VS Code Extension):

  • Windows: %APPDATA%\Code\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json

  • macOS: ~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json

  • Linux: ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json

Option 1: Standard Installation Configuration

{ "mcpServers": { "ollama-deep-researcher": { "command": "node", "args": ["path/to/mcp-server-ollama-deep-researcher/build/index.js"], "env": { "LANGSMITH_TRACING": "true", "LANGSMITH_ENDPOINT": "https://api.smith.langchain.com", "LANGSMITH_API_KEY": "your-langsmith-key", "LANGSMITH_PROJECT": "ollama-deep-researcher-mcp-server", "TAVILY_API_KEY": "your-tavily-key", // Include tvly- prefix "PERPLEXITY_API_KEY": "your-perplexity-key", "PYTHONPATH": "path/to/mcp-server-ollama-deep-researcher/src" } } } }

Note: Replace paths with absolute paths for your system:

  • Windows: Use C:\\Users\\username\\path\\to\\mcp-server-ollama-deep-researcher

  • macOS/Linux: Use /Users/username/path/to/mcp-server-ollama-deep-researcher

For macOS/Linux, you may also want to add:

"PYTHONUNBUFFERED": "1"

Option 2: Docker Installation Configuration

If you're using the Docker container, you can configure the MCP client to connect to the running container:

{ "mcpServers": { "ollama-deep-researcher": { "command": "docker", "args": ["exec", "-i", "ollama-deep-researcher-mcp", "node", "build/index.js"], "env": {} } } }

This configuration assumes the Docker container is running. The environment variables are already set in the Docker container, so you don't need to specify them in the MCP client configuration.

Prompt Example: "Configure with perplexity and deepseek-r1:8b then research AI-First Applications"

The Ollama Research Workflow

The research process is inspired by IterDRAG. This approach decomposes a query into sub-queries, retrieves documents for each one, answers the sub-query, and then builds on the answer by retrieving docs for the second sub-query.

The process works as follows:

  1. Given a user-provided topic, use a local LLM (via Ollama) to generate a web search query

  2. Uses a search engine (configured for Tavily) to find relevant sources

  3. Uses LLM to summarize the findings from web search related to the user-provided research topic

  4. Then, it uses the LLM to reflect on the summary, identifying knowledge gaps

  5. It generates a new search query to address the knowledge gaps

  6. The process repeats, with the summary being iteratively updated with new information from web search

  7. It will repeat down the research rabbit hole

  8. Runs for a configurable number of iterations

Outputs

The output is a markdown file containing the research summary, with citations to all sources used during the research process.

All sources gathered during research are preserved and can be referenced in the final output:

  • Verify your path arg points to the actual location of the index.js in this repo

  • Ensure there are no extra spaces or quotes around the API key

  • Check if your API key has sufficient credits/permissions

MCP Server Issues

  • Use the MCP Inspector for debugging:

npx @modelcontextprotocol/inspector node path/to/server/index.js --model llama3.2 --max-loops 3 --search-api tavily

Docker Issues

  • If you're having issues with the Docker container:

    • Check if the container is running: docker ps

    • View container logs: docker logs ollama-deep-researcher-mcp

    • Ensure your .env file contains valid API keys

    • Verify Ollama is running on your host machine and accessible from the container

    • If using host.docker.internal doesn't work, try using your host machine's IP address in the OLLAMA_BASE_URL environment variable

    • For network issues between containers, ensure they're on the same Docker network

  • If you're running Ollama in a container:

    • Uncomment the Ollama service in docker-compose.yml

    • Ensure the Ollama container has enough resources allocated

    • Pull the model in the Ollama container: docker exec -it ollama ollama pull deepseek-r1:8b

Build Issues

  • If npm run build fails with "'node' is not recognized":

    1. Ensure Node.js is properly installed

    2. Add Node.js to your system PATH:

      • Windows: Edit system environment variables → Environment Variables → Path → Add Node.js installation directory

      • macOS/Linux: Usually handled by the installer

    3. Restart your terminal/computer

    4. Try running node --version to verify the installation

Python Issues

Windows:

  • Ensure Python is in your PATH

  • Try using python instead of python3

  • Check if pip is installed: python -m pip --version

macOS/Linux:

  • Use python3 instead of python
