+# Build Your First MCP Server: Leave Management
+This AI tool helps an HR with leave management related tasks. The codebase here 
+is for MCP server that interacts with mock leave database and responds to MCP client queries
+
+# Setup steps
+1. Install Claude Desktop
+2. Install uv by running `pip install uv`
+3. Run `uv init my-first-mcp-server` to create a project directory
+4. Few folks may get type errors for which you can run `pip install --upgrade typer` to upgrade typer library to its latest version
+5. Write code in main.py for leave management server
+6. Install this server inside Claude desktop by running `uv run mcp install main.py` in the project directory
+7. Kill any running instance of Claude from Task Manager. Restart Claude Desktop
+8. In Claude desktop, now you will see tools from this server
