The Model Context Protocol (MCP) server is designed to facilitate Retrieval-Augmented Generation (RAG) over GitHub repositories, enabling efficient code retrieval and interaction.

RagThisCode

Setup an MCP server to do RAG over any public GitHub repo or any of your private repos

Demos powered by RagThisCode

Installation

Install uv: https://docs.astral.sh/uv/getting-started/installation/

Create a github access token at: https://github.com/settings/personal-access-tokens. You can make it never expire and give it access to only public repositories (unless you want to do RAG on your private repos as well). It seems that it only works if you use Tokens (classic) and select the scope public_repo.

Add:

export GITHUB_ACCESS_TOKEN="ghp_....."

to your .bashrc or .zshrc.

Create an OpenAI API key: https://platform.openai.com/docs/overview

Add:

export OPENAI_API_KEY="sk-proj-....."

to your .bashrc or .zshrc.

Restart your terminal for your exports to be effective.

Running

To fetch code from GitHub, run:

uv run store_code_in_vector_db.py

To start the MCP server, run:

uv run server.py

To start the chat client that will connect to the MCP server that you just started, run:

uv run chat.py

To start the proxy

uv run proxy.py

To start the client

python3 -m http.server 5173 --bind 127.0.0.1 --directory "./frontend"
