Run llama.cpp with Duck Duck Go Search

Sad Local Story

I am mostly using local llms for my basic automation activities and general ai usage. The biggest problem i faced was absence of updated information from llm, often i had to switch to google search or gemini for updated information.

We have already seen in previous blogs how LLM can interact with tools and and execute tool_calling functionality. When we need to get information from the internet which is frequently changing and the data source is not managed by us, then writing tool and maintaining it is a big headache.

Motivation: Feeling Locally Rich with Poor Man's GPU

Then comes search engines to the rescue, Google being the most reliable and Duck Duck Go being also of the contender. Let's see how the llama.cpp interface when invoked without MCP Server

We have a ready-made search mcp server available here https://github.com/nickclyde/duckduckgo-mcp-server

Some Hacker's Master class on Terminal

Following are the instruction to run it locally

1git clone https://github.com/nickclyde/duckduckgo-mcp-server.git

Change line as below:

Installed fastmcp using pip install fastmcp in custom venv not with uv

Running Server and Result

Ran server using:

1fastmcp run src/duckduckgo_mcp_server/server.py --transport streamable-http

Once this executes successfully, we should get server running at

Thanks!
