Implementation Reference

• src/index.ts:509-527 (schema)

  Input schema definition and tool registration for the 'delete_zone' MCP tool, including required parameters 'name' and 'confirm'.

  {
    name: "delete_zone",
    description: "Delete a memory zone and all its entities/relations.",
    inputSchema: {
      type: "object",
      properties: {
        name: {
          type: "string",
          description: "Zone name to delete (cannot be 'default')"
        },
        confirm: {
          type: "boolean",
          description: "Confirmation flag, must be true",
          default: false
        }
      },
      required: ["name", "confirm"]
    }
  },

• src/index.ts:1183-1214 (handler)

  Execution handler for the 'delete_zone' tool within the CallToolRequestSchema handler. Validates confirmation, calls kgClient.deleteMemoryZone(name), and formats success/error responses.

  else if (toolName === "delete_zone") {
    const name = params.name;
    const confirm = params.confirm === true;
    
    if (!confirm) {
      return formatResponse({
        success: false,
        error: "Confirmation required. Set confirm=true to proceed with deletion."
      });
    }
    
    try {
      const result = await kgClient.deleteMemoryZone(name);
      
      if (result) {
        return formatResponse({
          success: true,
          message: `Zone "${name}" deleted successfully`
        });
      } else {
        return formatResponse({
          success: false,
          error: `Failed to delete zone "${name}"`
        });
      }
    } catch (error) {
      return formatResponse({
        success: false,
        error: `Error deleting zone: ${(error as Error).message}`
      });
    }
  }
