+# AI Agent Node Extraction Test Guide
+
+This document describes how to test the MCP server's ability to extract and provide the AI Agent node source code from n8n.
+
+## Test Scenario
+
+An MCP client (like an AI assistant) requests the source code for n8n's AI Agent node, and the MCP server successfully extracts and returns it.
+
+## Implementation Overview
+
+### 1. New MCP Tools Added
+
+- **`get_node_source_code`**: Extracts source code for any n8n node
+- **`list_available_nodes`**: Lists all available n8n nodes
+
+### 2. New Components
+
+- **`NodeSourceExtractor`** (`src/utils/node-source-extractor.ts`): Handles file system access to extract node source code
+- **Resource endpoint**: `nodes://source/{nodeType}` for accessing node code via resources
+
+### 3. Test Infrastructure
+
+- **Docker setup** (`docker-compose.test.yml`): Mounts n8n's node_modules for source access
+- **Test scripts**: Multiple test approaches for different scenarios
+
+## Running the Tests
+
+### Option 1: Docker-based Test
+
+```bash
+# Build the project
+npm run build
+
+# Run the comprehensive test
+./scripts/test-ai-agent-extraction.sh
+```
+
+This script will:
+1. Build Docker containers
+2. Start n8n and MCP server
+3. Check for AI Agent node availability
+4. Test source code extraction
+
+### Option 2: Standalone MCP Test
+
+```bash
+# Build the project
+npm run build
+
+# Ensure n8n is running (locally or in Docker)
+docker-compose -f docker-compose.test.yml up -d n8n
+
+# Run the MCP client test
+node tests/test-mcp-extraction.js
+```
+
+### Option 3: Manual Testing
+
+1. Start the environment:
+```bash
+docker-compose -f docker-compose.test.yml up -d
+```
+
+2. Use any MCP client to connect and request:
+```json
+{
+  "method": "tools/call",
+  "params": {
+    "name": "get_node_source_code",
+    "arguments": {
+      "nodeType": "@n8n/n8n-nodes-langchain.Agent",
+      "includeCredentials": true
+    }
+  }
+}
+```
+
+## Expected Results
+
+### Successful Extraction Response
+
+```json
+{
+  "nodeType": "@n8n/n8n-nodes-langchain.Agent",
+  "sourceCode": "/* AI Agent node JavaScript code */",
+  "location": "/usr/local/lib/node_modules/n8n/node_modules/@n8n/n8n-nodes-langchain/dist/nodes/agents/Agent/Agent.node.js",
+  "credentialCode": "/* Optional credential code */",
+  "packageInfo": {
+    "name": "@n8n/n8n-nodes-langchain",
+    "version": "1.x.x",
+    "description": "LangChain nodes for n8n"
+  }
+}
+```
+
+## How It Works
+
+1. **MCP Client Request**: Client calls `get_node_source_code` tool with node type
+2. **Server Processing**: MCP server receives request and invokes `NodeSourceExtractor`
+3. **File System Search**: Extractor searches known n8n paths for the node file
+4. **Source Extraction**: Reads the JavaScript source code and optional credential files
+5. **Response Formation**: Returns structured data with source code and metadata
+
+## Troubleshooting
+
+### Node Not Found
+
+If the AI Agent node is not found:
+
+1. Check if langchain nodes are installed:
+```bash
+docker exec n8n-test ls /usr/local/lib/node_modules/n8n/node_modules/@n8n/
+```
+
+2. Install langchain nodes:
+```bash
+docker exec n8n-test npm install -g @n8n/n8n-nodes-langchain
+```
+
+### Permission Issues
+
+Ensure the MCP container has read access to n8n's node_modules:
+```yaml
+volumes:
+  - n8n_modules:/usr/local/lib/node_modules/n8n/node_modules:ro
+```
+
+### Alternative Node Types
+
+You can test with other built-in nodes:
+- `n8n-nodes-base.HttpRequest`
+- `n8n-nodes-base.Code`
+- `n8n-nodes-base.If`
+
+## Success Criteria
+
+The test is successful when:
+1. ✅ MCP server starts and accepts connections
+2. ✅ Client can discover the `get_node_source_code` tool
+3. ✅ Server locates the AI Agent node in the file system
+4. ✅ Complete source code is extracted and returned
+5. ✅ Response includes metadata (location, package info)
+
+## Security Considerations
+
+- Source code extraction is read-only
+- Access is limited to n8n's node_modules directory
+- Authentication token required for MCP server access
+- No modification of files is possible
+
+## Next Steps
+
+After successful testing:
+1. Deploy to production environment
+2. Configure proper authentication
+3. Set up monitoring for extraction requests
+4. Document available node types for users
