Implementation Reference

• src/core/MCPServer.ts:231-237 (handler)

  Tool handler for 'delete_record' that validates arguments and calls dataService.deleteRecord, returning success status.

  case 'delete_record': {
    return await safeExecute(toolName, async () => {
      const args = validateInput(DeleteRecordArgsSchema, request.params.arguments);
      const success = await this.dataService.deleteRecord(args.resourceUri, args.recordId);
      return { success, id: args.recordId };
    });
  }

• src/types/index.ts:93-96 (schema)

  Zod input schema defining resourceUri and recordId for the delete_record tool.

  export const DeleteRecordArgsSchema = z.object({
    resourceUri: z.string().describe('URI of the resource'),
    recordId: z.string().describe('ID of the record to delete'),
  });

• src/core/MCPServer.ts:158-162 (registration)

  Tool registration in handleListTools method, providing name, description, and input schema.

  {
    name: 'delete_record',
    description: 'Delete a record from a resource',
    inputSchema: getInputSchema(DeleteRecordArgsSchema),
  },

• src/examples/services/InMemoryDataService.ts:183-193 (helper)

  Core implementation of deleteRecord in InMemoryDataService, which deletes the record by ID from the in-memory Map.

  public async deleteRecord(uri: string, id: string): Promise<boolean> {
    this.validateResource(uri);
    
    const resourceData = this.data.get(uri)!;
    
    if (!resourceData.has(id)) {
      throw new Error(`Record not found: ${id}`);
    }
    
    return resourceData.delete(id);
  }
