+# KALI MCP integration
+
+## Steps
+
+1. Compile base Docker image.
+
+```bash
+docker build ../../ -t pentestagent:latest 
+```
+
+2. Configure .env file with API tokens and models for AI.
+
+```
+OPENAI_API_KEY=sk-...
+PENTESTAGENT_MODEL=gpt-5
+```
+
+3. Configure the IP address or hostname in the mcp_servers.json file:
+
+``` json
+{
+  "mcpServers": {
+    "kali": {
+      "command": "python",
+      "args": ["MCP-Kali-Server/mcp_server.py", "--server", "http://<hostname>:5000"]
+    }
+  }
+}
+```
+
+4. Launch docker-compose
+
+```bash
+# Build
+docker-compose build
+
+# Run
+docker-compose run --rm pentestagent
+
+```
+
+At this point, you will be able to check the MCP servers with the /mcp list command
