+# Rag MCP server
+
+This is a simple gradio server that allows you to run a RAG (Retrieval-Augmented Generation) model using the
+MCP (Model Control Protocol) interface.
+
+# Requirements
+
+- UV: The python package manager. Visit https://github.com/astral-sh/uv
+
+Since the server uses SERPER API, you will need to set the `SERPER_API_KEY` environment variable to
+enable the search functionality. You can export it in your shell:
+
+```bash
+export SERPER_API_KEY=your_serper_api_key
+```
+
+
+# Installation
+```bash
+uv sync
+```
+
+# Usage
+
+Just run the gradio application: 
+
+```bash
+uv run gradio app.py
+```
+
+
+# Access the server
+Open your browser and go to `http://localhost:7860` to access the RAG MCP server.
+
+You can see the [gradio docs](https://www.gradio.app/guides/building-mcp-server-with-gradio) for more information on how to use the interface.
