Implementation Reference
- src/index.ts:482-492 (handler)Main handler function for the 'test_connection' tool. Delegates to RAGService.testEmbeddingService() and returns formatted MCP response with connection status.
private async handleTestConnection() { const isConnected = await this.ragService.testEmbeddingService(); return { content: [ { type: 'text', text: JSON.stringify({ connected: isConnected }, null, 2), }, ], }; } - src/index.ts:211-218 (schema)Tool registration entry including schema definition. Defines 'test_connection' tool with empty input schema (no parameters required).
{ name: 'test_connection', description: 'Test the connection to the embedding service', inputSchema: { type: 'object', properties: {}, }, }, - src/index.ts:275-277 (registration)Dispatch registration in CallToolRequestHandler switch statement that routes 'test_connection' calls to the handler.
case 'test_connection': return await this.handleTestConnection(); - src/services/ragService.ts:263-270 (helper)RAGService helper method that calls EmbeddingService.testConnection() with error handling.
async testEmbeddingService(): Promise<boolean> { try { return await this.embeddingService.testConnection(); } catch (error) { logger.error(`Embedding service test failed: ${error}`); return false; } } - Core test implementation in EmbeddingService. Generates a test embedding and validates its dimension matches expected CONFIG.EMBEDDING_DIMENSION.
async testConnection(): Promise<boolean> { try { const testEmbedding = await this.generateSingleEmbedding('test'); return testEmbedding.length === CONFIG.EMBEDDING_DIMENSION; } catch (error) { logger.error(`Embedding service test failed: ${error}`); return false; } }
