Implementation Reference
- src/index.ts:821-848 (handler)The handler function for 'mongodb_delete_document' tool. Connects to MongoDB using getMongoClient, parses the filter JSON, executes deleteMany on the specified collection, returns content with the number of deleted documents.private async mongodbDeleteDocument( databaseName: string, collectionName: string, filterJson: string ) { const client = await this.getMongoClient(); try { const db = client.db(databaseName); const collection = db.collection(collectionName); const filter = JSON.parse(filterJson); const result = await collection.deleteMany(filter); return { content: [ { type: "text", text: `Удалено документов: ${result.deletedCount}`, }, ], }; } catch (error) { throw new Error( `Ошибка удаления документа: ${error instanceof Error ? error.message : String(error)}` ); } finally { await client.close(); } }
- src/index.ts:277-298 (schema)Input schema definition for the 'mongodb_delete_document' tool in the list of tools returned by ListToolsRequestHandler.{ name: "mongodb_delete_document", description: "Удаляет документ(ы) из коллекции по фильтру", inputSchema: { type: "object", properties: { databaseName: { type: "string", description: "Имя базы данных", }, collectionName: { type: "string", description: "Имя коллекции", }, filter: { type: "string", description: "JSON строка с фильтром для удаления", }, }, required: ["databaseName", "collectionName", "filter"], }, },
- src/index.ts:374-379 (registration)Registration/dispatch in the CallToolRequestHandler switch statement that invokes the mongodbDeleteDocument handler.case "mongodb_delete_document": return await this.mongodbDeleteDocument( args?.databaseName as string, args?.collectionName as string, args?.filter as string );
- src/server.py:541-556 (handler)Python implementation of the mongodb_delete_document handler function. Parses filter JSON, performs delete_many, returns deleted count. Note: dispatch is commented out in handle_request.def mongodb_delete_document( database_name: str, collection_name: str, filter_json: str ) -> str: """Deletes document(s) by filter""" client = MongoClient(MONGODB_URI) try: db = client[database_name] collection = db[collection_name] filter_dict = json.loads(filter_json) result = collection.delete_many(filter_dict) return f"Deleted documents: {result.deleted_count}" except Exception as e: raise Exception(f"Error deleting document: {str(e)}") finally: client.close()
- src/server.py:264-285 (schema)Input schema for 'mongodb_delete_document' in the Python get_tools() function.{ "name": "mongodb_delete_document", "description": "Deletes document(s) from collection by filter", "inputSchema": { "type": "object", "properties": { "databaseName": { "type": "string", "description": "Database name", }, "collectionName": { "type": "string", "description": "Collection name", }, "filter": { "type": "string", "description": "JSON string with deletion filter", }, }, "required": ["databaseName", "collectionName", "filter"], }, },
