+## 7. Method E: Cursor IDE Setup
+
+**Prerequisites:**
+
+- [Node.js](https://nodejs.org/) (version 18 or higher)
+- npm (version 9 or higher)
+- [Cursor](https://cursor.sh/) IDE installed
+
+**Setup Steps:**
+
+### 7.1. Install iExec MCP Server
+
+```bash
+npm install -g @iexec/mcp-server
+```
+
+### 7.2. Configure Cursor
+
+1. **Open Cursor Settings:**
+
+   - Press `Cmd+,` (macOS) or `Ctrl+,` (Windows/Linux)
+   - Or go to **Cursor > Preferences > Settings**
+
+2. **Search for "MCP" in settings:**
+
+   - Look for "Model Context Protocol" or "MCP" settings
+
+3. **Add MCP Server Configuration:**
+
+   **Option A: Using Settings UI (if available):**
+
+   - Add a new MCP server entry
+   - Set the command to: `@iexec/mcp-server`
+   - Add environment variables:
+     - `PRIVATE_KEY_PATH`: `/ABSOLUTE/PATH/TO/YOUR/KEYSTORE/wallet.json`
+     - Or `PRIVATE_KEY`: `0xYOUR_PRIVATE_KEY`
+
+   **Option B: Manual Configuration:**
+
+   - Open Cursor's configuration file (usually in user settings)
+   - Add the following configuration:
+
+   ```json
+   {
+     "mcpServers": {
+       "iexec-mcp-server": {
+         "command": "npx",
+         "args": ["-y", "@iexec/mcp-server@latest"],
+         "env": {
+           "PRIVATE_KEY_PATH": "/ABSOLUTE/PATH/TO/YOUR/KEYSTORE/wallet.json"
+         }
+       }
+     }
+   }
+   ```
+
+   **Option C: Using Cursor's AI Features:**
+
+   - Open the AI chat panel in Cursor
+   - Type: "Configure MCP server for iExec with private key path: /path/to/wallet.json"
+   - Cursor should help you set up the configuration
+
+4. **Restart Cursor** - The iExec MCP server should now be available in your AI interactions
+
+### 7.3. Alternative: Local Development Setup
+
+If you prefer to run from source:
+
+```bash
+git clone https://github.com/iexecBlockchainComputing/iexec-mcp-server.git
+cd iexec-mcp-server
+npm install
+npm run build
+```
+
+Then configure Cursor to use the local build:
+
+```json
+{
+  "mcpServers": {
+    "iexec-mcp-server": {
+      "command": "node",
+      "args": ["/ABSOLUTE/PATH/TO-IEXEC-MCP-SERVER-REPO/build/index.js"],
+      "env": {
+        "PRIVATE_KEY_PATH": "/ABSOLUTE/PATH/TO/wallet.json"
+      }
+    }
+  }
+}
+```
