API & Client Usage

REST/JSON-RPC: Exposes all AEM operations via HTTP endpoints
Supported Operations: Page/asset CRUD, component validation/update, search, rollout, publish, text/image extraction, and more
AI/LLM: Send natural language commands to the server (via API or Telegram)
Telegram Bot: Connect your bot using TELEGRAM_BOT_TOKEN and chat with your AEM instance

AI IDE Integration (Cursor, Cline, etc.)

AEM MCP Server is compatible with modern AI IDEs and code editors that support MCP protocol, such as Cursor and Cline.

How to Connect:

Install and run the AEM MCP Server as described above.
Configure your IDE to connect to the MCP server. Example for Cursor/Cline:
- Open your IDE's MCP server settings.
- Add a new server with:
  - Type: Custom MCP
  - Command: node
  - Args: ["/absolute/path/to/dist/mcp-server.js"]
  - Port: 8080 (or as configured)
  - Auth: Use MCP_USERNAME/MCP_PASSWORD from your .env
Restart your IDE and connect. The IDE will now be able to:
- List, search, and manage AEM content
- Run MCP methods (CRUD, search, rollout, etc.)
- Use AI/LLM features if enabled

Custom MCP Clients

You can build your own MCP client in any language that supports HTTP/JSON-RPC.
See the Usage Examples for API call patterns.
Authenticate using basic auth (MCP_USERNAME/MCP_PASSWORD).
All MCP methods are available via the /api endpoint.

Security

Auth required for all operations (see MCP_USERNAME/MCP_PASSWORD)
Environment-based configuration for safe deployment
All destructive operations require explicit parameters and validation

Troubleshooting

Common Issues

Connection Issues

# Test AEM connection
curl -u admin:admin http://localhost:4502/libs/granite/core/content/login.html

# Check server health
curl http://localhost:3001/health

Authentication Problems

Verify AEM credentials in .env file
Check MCP_USERNAME and MCP_PASSWORD for API access
Ensure AEM user has sufficient permissions

Page Creation Issues

Empty pages without jcr: Use proper template parameter
Pages not visible in Author: Ensure template exists and is valid
Template not found: Verify template path and permissions

Component Update Failures

Component not found: Verify component path exists
Update failed: Check component properties and validation
Permission denied: Ensure user has write access

Performance Optimization

Use pagination with limit parameter for large result sets
Set appropriate depth values for page listing
Configure AEM_QUERY_TIMEOUT for slow queries
Use bulk operations for multiple component updates

Debugging

# Enable debug logging
DEBUG=aem-mcp:* npm run dev

# Check detailed health status
curl http://localhost:3001/health

# List all available methods
curl -u admin:admin http://localhost:3001/api/methods

Common Use Cases

Content Migration

// 1. List source pages
const pages = await listPages({ siteRoot: '/content/source', depth: 3 });

// 2. Create target pages with templates
for (const page of pages.data.pages) {
  await createPage({
    parentPath: '/content/target',
    title: page.title,
    template: '/conf/target/settings/wcm/templates/page'
  });
}

// 3. Copy components
const components = await scanPageComponents({ pagePath: sourcePage });
for (const component of components.data.components) {
  await createComponent({
    pagePath: targetPage,
    componentType: component.resourceType,
    properties: component.properties
  });
}

Bulk Content Updates

// Update multiple text components
const updates = [
  {
    componentPath: '/content/site/page1/jcr:content/text1',
    properties: { text: 'Updated content 1' }
  },
  {
    componentPath: '/content/site/page2/jcr:content/text2',
    properties: { text: 'Updated content 2' }
  }
];

await bulkUpdateComponents({
  updates,
  validateFirst: true,
  continueOnError: false
});

Asset Management Workflow

// 1. Upload assets
await uploadAsset({
  parentPath: '/content/dam/project',
  fileName: 'hero.jpg',
  fileContent: base64Content,
  metadata: { 'dc:title': 'Hero Image' }
});

// 2. Update page to use new asset
await updateComponent({
  componentPath: '/content/site/home/jcr:content/hero',
  properties: { fileReference: '/content/dam/project/hero.jpg' }
});

// 3. Publish changes
await activatePage({ pagePath: '/content/site/home' });

Search and Discovery

// Find pages by content
const results = await searchContent({
  type: 'cq:Page',
  fulltext: 'product launch',
  path: '/content/mysite'
});

// Get detailed page information
for (const result of results.data.results) {
  const content = await getPageContent({ pagePath: result.path });
  const components = await scanPageComponents({ pagePath: result.path });
}

API Reference

Authentication

All API endpoints require HTTP Basic Authentication:

Authorization: Basic base64(username:password)

Response Format

All responses follow this structure:

{
  "success": true,
  "operation": "methodName",
  "timestamp": "2024-01-01T00:00:00.000Z",
  "data": {
    // Method-specific response data
  }
}

Error Handling

Error responses include structured information:

{
  "success": false,
  "operation": "methodName",
  "timestamp": "2024-01-01T00:00:00.000Z",
  "error": {
    "code": "ERROR_CODE",
    "message": "Human readable error message",
    "details": {},
    "recoverable": true,
    "retryAfter": 5000
  }
}

Error Handling Best Practices

The AEM MCP Server follows REST API best practices by returning HTTP 200 status codes with structured error information in the response body. This approach provides several benefits:

Consistent Response Format: All responses, whether successful or not, follow the same JSON structure
Detailed Error Information: Error responses include specific codes, messages, and details
Client-Side Processing: Clients can easily parse and handle errors programmatically
Recoverable vs. Fatal Errors: The recoverable flag indicates if retrying might succeed
Retry Guidance: When appropriate, retryAfter suggests a wait time before retrying

Example Error Handling in Client Code:

async function callMcpMethod(method, params) {
  const response = await fetch(`/api/methods/${method}`, {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify(params)
  });
  
  const result = await response.json();
  
  if (!result.success) {
    // Handle error based on error code and details
    console.error(`Error in ${method}:`, result.error.message);
    
    if (result.error.recoverable && result.error.retryAfter) {
      // Implement retry logic
      console.log(`Retrying after ${result.error.retryAfter}ms`);
      await new Promise(resolve => setTimeout(resolve, result.error.retryAfter));
      return callMcpMethod(method, params); // Recursive retry
    }
    
    throw new Error(`${result.error.code}: ${result.error.message}`);
  }
  
  return result.data;
}

Common Error Codes:

Error Code	Description	Recoverable
`INVALID_PARAMS`	Missing or invalid parameters	No
`PATH_NOT_FOUND`	Specified path does not exist	No
`PERMISSION_DENIED`	Insufficient permissions	No
`TEMPLATE_NOT_FOUND`	Template does not exist	No
`COMPONENT_NOT_FOUND`	Component does not exist	No
`NETWORK_ERROR`	Connection to AEM failed	Yes
`TIMEOUT`	Operation timed out	Yes
`RESOURCE_LOCKED`	Resource is locked by another process	Yes
`SERVER_BUSY`	Server is under heavy load	Yes
`VALIDATION_FAILED`	Content validation failed	No
