---- - -## 🔍 Core Components Deep Dive - -### Code Overview - -#### index.ts - Express Server Entry Point -- Loads authentication configuration from environment variables -- Sets up Express server with JSON parsing and JWT authorization middleware -- Configures `/api/messages` endpoint for Bot Framework message processing -- Manages observability lifecycle (start on launch, shutdown on error/close) -- Handles graceful shutdown on SIGINT/SIGTERM signals - -#### agent.ts - Agent Application Setup -- Creates `AgentApplication` with memory storage and file download support -- Registers activity handlers: - - **Message Activity**: Delegates to `N8nAgent.handleAgentMessageActivity` - - **InstallationUpdate Activity**: Delegates to `N8nAgent.handleInstallationUpdateActivity` - -#### n8nAgent.ts - Core Business Logic -- **Message Handler**: Enforces installation → terms acceptance → processing flow -- **Installation Handler**: Sets state flags and sends welcome/goodbye messages -- **Notification Handlers**: Processes email and Word @-mention notifications with two-stage flow (metadata extraction → content retrieval via n8n) -- **getN8nClient**: Discovers MCP tool servers and creates configured N8nClient - -#### n8nClient.ts - Webhook Client with Observability -- Constructs JSON payload with user message, sender name, and MCP tool metadata -- POSTs to `N8N_WEBHOOK_URL` with optional authentication header -- Parses response expecting `{ output: "text" }` format -- Wraps invocations with nested observability spans: - - **InvokeAgentScope**: Tracks entire agent invocation - - **InferenceScope**: Tracks n8n workflow execution with input/output recording - -#### mcpToolRegistrationService.ts - MCP Tool Discovery -- `getMcpServers`: Lists tool servers from configuration service, retrieves agentic token if needed -- `getTools`: Connects to each MCP server via HTTP transport, lists available tools with schemas -- Returns array of `McpServer` objects with tool metadata for n8n workflows - -#### telemetry.ts - Observability Configuration -- Configures `ObservabilityManager` with service name and version -- Can be extended with exporters (Console, OTLP, etc.) -- Lifecycle managed in `index.ts` - ---- - -## 🎯 Design Patterns and Best Practices - -### Separation of Concerns -- **index.ts**: Server infrastructure -- **agent.ts**: Activity routing -- **n8nAgent.ts**: Business logic -- **n8nClient.ts**: External integration -- **mcpToolRegistrationService.ts**: Tool management -- **telemetry.ts**: Observability configuration - -### Observability-First Design -- All n8n invocations wrapped with InvokeAgentScope -- Inference operations tracked with InferenceScope -- Error recording for debugging -- Proper span disposal in finally blocks - -### Graceful Degradation -- MCP tool discovery failures don't block agent -- Empty tool array if discovery fails -- Webhook errors return user-friendly messages -- Fallback responses when n8n unavailable - -### Security Best Practices -- JWT authorization on all endpoints -- Environment-based secrets (no hardcoded credentials) -- Optional authentication header for n8n webhook -- Agentic authentication for MCP tool access - ---- - -## 🛠️ Extension Points - -### Adding Persistent State -Replace in-memory flags with persistent storage: -```typescript -// Instead of class properties -private stateService: IStateService; - -async handleAgentMessageActivity(turnContext, state) { - const userState = await this.stateService.getUserState(userId); - if (!userState.termsAccepted) { ... } -} -``` - -### Custom Notification Types -Add more notification handlers: -```typescript -agentApplication.onAgentNotification("CustomNotificationType", - async (context, state, notification) => { - await n8nAgent.handleCustomNotification(context, state, notification); - } -); -``` - -### Enhanced Observability -Add custom metrics and tags: -```typescript -scope?.recordCustomMetric('n8n_response_time_ms', duration); -scope?.addTags({ workflow_id: 'xyz', user_tier: 'premium' }); -``` - -### Webhook Response Enrichment -Process structured responses from n8n: -```typescript -interface N8nResponse { - output: string; - actions?: string[]; - metadata?: Record; -} - -// Handle actions, show adaptive cards, etc. -``` - ---- - -## **Summary** - -This n8n agent provides a stateful, observable bridge between Microsoft 365 and n8n workflows. It handles installation lifecycle, enforces terms acceptance, forwards messages and notifications to n8n with MCP tool context, and provides comprehensive telemetry for monitoring and debugging. The architecture separates concerns cleanly, enabling easy extension and maintenance while following Microsoft Agent 365 best practices. - - -### Features - -- **Message handling** from Teams chats with conversation state tracking -- **Installation/uninstallation lifecycle management** with welcome messages -- **Terms and conditions acceptance flow** before agent activation -- **Email notification support** - processes email notifications via agent notifications -- **Word document @-mention support** - handles @-mentions in Word comments via agent notifications -- **MCP Tool Server integration** - discovers and connects to Microsoft 365 MCP tool servers -- **Telemetry and observability** with Agent 365 SDK (InvokeAgentScope, InferenceScope) -- **Graceful shutdown** handling for SIGINT and SIGTERM signals diff --git a/nodejs/n8n/sample-agent/README.md b/nodejs/n8n/sample-agent/README.md index d9b3f615..117a998e 100644 --- a/nodejs/n8n/sample-agent/README.md +++ b/nodejs/n8n/sample-agent/README.md @@ -1,31 +1,159 @@ -# n8n Sample Agent - Node.js +# n8n Sample Agent -This sample demonstrates how to build an agent using n8n in Node.js with the Microsoft Agent 365 SDK.
