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:

Generate a web search query
Gather web search results via Tavily or Perplexity API
Summarize the search results
Reflect on the summary to examine knowledge gaps
Generate new search queries to address the gaps
Iteratively improve the summary through multiple research cycles
Provide a final markdown summary with all sources used

Prerequisites

Node.js (for running the MCP server)
- Download and install from https://nodejs.org/
- Ensure Node.js is added to your system PATH
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:
- Tavily API key (get one at https://tavily.com)
- Perplexity API key (get one at https://perplexity.ai)
- LangSmith API key (get one at https://smith.langchain.com) for tracing and monitoring

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:

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

Download and install Ollama for your platform
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

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

Build the TypeScript code:

npm run build

Pull a local LLM from Ollama:

ollama pull deepseek-r1:8b

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

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:

Given a user-provided topic, use a local LLM (via Ollama) to generate a web search query
Uses a search engine (configured for Tavily) to find relevant sources
Uses LLM to summarize the findings from web search related to the user-provided research topic
Then, it uses the LLM to reflect on the summary, identifying knowledge gaps

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

It will repeat down the research rabbit hole
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:

Troubleshooting

Here are solutions to common issues you might encounter:

Ollama Connection Issues

Make sure Ollama is running: Execute ollama list in your terminal

Try running ollama in terminal mode by closing the app (System Tray/Menu Bar), and executing ollama serve

          - Check if Ollama is accessible at `localhost:11434`, `0.0.0.0:11434`, or `127.0.0.1:11434`

API Key Issues

Verify your API key is correctly set in the configuration file
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

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
Check if pip is installed: python3 -m pip --version
You may need to install pip: sudo apt install python3-pip (Ubuntu/Debian) or brew install python3 (macOS)

Error Handling

The server provides clear error messages for:

Missing or invalid API keys
Configuration issues
Search API problems
LLM processing errors

Enhancements Needed

Tighter re-integration and validation of langgraph for additional interesting use cases.
